SECTION ONE
GENERAL INFORMATION
BATS
GENERAL INFORMATION
The Model 4460C has the same features and functions as the 4460B but internally has a new CPU
and IDE interface. These new components allow for faster data processing with reduced stress on
the internal CPU.
1.
GENERAL INFORMATION
The EdgeTech Broadband Acoustic Tracking System (BATS) is an Ultra Short BaseLine (USBL) underwater tracking/navigation system. The O EdgeTech BATS consists of a hull mounted Transducer
(Model 4213C-B), that is both a listening Hydrophone and an Interrogator, a Deck Cable (Model
4113C), Transceiver (Model 4460C) and a PC (Customer or EdgeTech Supplied).
For a complete system from EdgeTech the BATS topside electronics are available in a 19-inch rack
type enclosure1. It consists of three 2U rack modules in a 6U Equipment Case containing the Transceiver (Model 4460B), the Rack Mount PC (running Windows) (Model 4451A) and a Keyboard/Display (Model 4452A). See Figures 1-1 and 1-2. The Transceiver is also available as a Desk
Top version (a 3.5 inch high chassis, 2U rack height), with a Laptop PC (EdgeTech or Customer
supplied). Another configuration of the BATS is a Portable version (Model 4461A) with a Laptop PC
(EdgeTech or Customer supplied). The Human Machine Interface (HMI) software (installed on the
PC) is called “Trackman”.
Transceiver
The Transceiver, Model 4460C, is the heart of the BATS. It is an integrated, Ultra-Short BaseLine
(USBL) acoustic signal processor designed to operate with up to four targets for a wide range of
subsea navigation and relocation tasks. It is contained in a 2U rack mount chassis and interfaces to
the Hydrophone/Interrogator and also the PC (running Windows software). The Transceiver Module
contains a receiver, digitizer and CPU along with a data acquisition module for external interface to
NMEA and analog sensors. It also contains the transmitter and power supplies. The Transceiver receives signals from the Transducer’s three element listening array (Hydrophone) and also Transmits
signals to its interrogation element.
The Transceiver interfaces to the EdgeTech USBL Hydrophone Model 4213C-B via its deck cable
Model 4113C. The Transceiver receives the signals from the Transducer and sends the raw data to
the PC for calculation of target position. The target types consist of transponders or responders
(Beacons).
Transducer (Hydrophone/Interrogator)
The Transducer, Model 4213C-B, is 2.875 inches (7.3cm) diameter by 17.53 inches (44.53cm) in
length and is calibrated in the 17 to 30kHz frequency band for the receiver and tuned to 15 to
23kHz for the transmitter. The Model 4213C-B-LF is the same size but is calibrated in the 8 to
1
* The 19-inch rack is a standard from EIA 310-D, IEC 60297 and DIN 41494 SC48D. One “Unit” in
a rack is 1.75 inches tall, 2U is 3.50 inches etc. The 19-inches refers to the rack width.
1-1
BATS
GENERAL INFORMATION
16kHz frequency band for the receiver and tuned to 12 to 17kHz for the transmitter.
For the
4213C-B-V1634, which is larger (4.5 inches diameter X 17.5” Long) and has a lower frequency interrogation element , the transmission is tuned in the 10-14kHz band.
Keyboard/Mouse and Display
The Keyboard & LCD Monitor (Model 4452A) are an integrated unit packaged in a 2U (3.5 inch
height) rack mount chassis. The LCD monitor and Keyboard are on rack slides which lock in the out
position. The LCD monitor is on friction hinges and can be positioned at any angle. The Keyboard/Mouse provide user interface to the Trackman program.
Computer
The Rack Mount PC (Model 4451A) is a 2U chassis containing a P4 Processor (minimum), Windows® XP operating system and the Trackman (Human-Machine Interface, (HMI)) software. The
“Trackman” software is EdgeTech’s Windows® based USBL user-interface software. Trackman
communicates with the BATS’ USBL Processor Module to allow modification of the target & system
parameters and also outputting of processed USBL data to Navigation software such as the
EdgeTech IPS software. The PC (Model 4451A) communicates with the USBL Processor Module
(Model 4460B) via its Ethernet port. The PC sends commands / parameter setup data to the USBL
Processor Module and receives raw beacon-position data from the USBL Processor Module. The PC
sends formatted beacon position data out its RS232 ports to interface to a Navigation System or
the case of the IPS software it can connect internally via an IP address and port#.
Trackman Software
The “Trackman” software is EdgeTech’s Windows® based USBL user-interface software. Trackman
communicates with the BATS’ USBL Processor Module to allow modification of the target & system
parameters and also outputting of processed USBL data to Navigation software such as the
EdgeTech IPS software.
IPS Software
The IPS software integrates the USBL data and the DGPS data to display and output tracked target
data relative to Latitude and longitude. The IPS is a Windows® based software and can be installed
on the same PC as the Trackman software.
Compatibility with older Trackpoint Systems
Beacons - The BATS can track the older Legacy beacons but with no improvement in range or accuracy from the older Trackpoint systems.
Hydrophone & Amplifier/VRU Model 4211A & 4740A from TP2 or 3 – Requires re-calibration of Hydrophone and modification to the 4740A Amplifier/VRU. Can use same Deck Cables, Model 4110B.
(Contact EdgeTech for more information.)
Hydrophone Model 4213C from TP3P - Requires re-calibration of Hydrophone. Can use same Deck
Cable, Model 4113C.

BATS
GENERAL INFORMATION
Beacons
The Model 4370A series of beacons are compatible with the BATS. They can be configured for Transponder or Responder operation. They typically output a 10ms discrete chirp signal. This means that
the composite signal is made up of a series of discrete frequencies.
External Sensors
The EdgeTech MRU (Motion Reference Unit) Model 4760B provides dynamic pitch and roll compensation for the BATS.

INSTALLATION
INSTALLATION
This section includes instructions for implementing a 4213C Hydrophone mounting assembly, making proper attachment of the 4113C Deck Cable and also the Transceiver side panel interface connections.
Hydrophone bearing, X, Y, Z offsets and pitch/roll offsets are generally determined at the time of
installation. This section includes sample procedures for determining those offsets.
2.1
HYDROPHONE/INTERROGATOR INSTALLATION
The manner and location in which the hydrophone assembly is mounted on the vessel is the single
most crucial element in the overall performance of the tracking system. In choosing a mounting
location, the operator should keep in mind that the BATS is by nature an extremely sensitive
acoustic system.
The hydrophone assembly must be in a position to "hear" the acoustic pulses
coming from the pinger, transponder, or responder in use. Mount the hydrophone as far as possible from noise sources, such as, propellers, thrusters, echo-sounder transducers, main engines,
generators and other underwater acoustic generating systems.
Ideally, the hydrophone should be mounted far enough from the nearest reflector to allow the direct arrival of a signal from the acoustic source before a reflected signal arrives. The minimum
recommended distance between the hydrophone array and the nearest reflector (which is usually
to the vessel's hull or keel) is one meter*. It is also important to keep the hydrophone below the
level of the vessel's keel for 360-degree coverage.
System performance can be degraded by "multi-path" or underwater signal reflections and reverberation. To minimize the possible effects of multi-path, choose a hydrophone location that is as far
away as possible from any surface that would make a good reflector of an acoustic pulse. Any hard
plate or structure near the hydrophone has the potential to reflect pulses into the hydrophone. The
air-water interface is also an extremely efficient acoustic reflector. Avoid any mounting locations
that would place the hydrophone in the proximity of bubbles.
*
1 meter = (1.33 milliseconds x 1500 meters/second)  2 way travel time
Consult the nearest EdgeTech representative for additional information on a specific installation.
NOTE: In some applications even though the hydrophone is over one meter directly away from the
hull, a signal can be reflected from an area along the keel and arrive within 1.3 ms of the direct
arrival thus causing interference. In these instances the hydrophone should be lowered further
away from the hull.
2-1
BATS AND PORTABLE BATS
2.1.1
INSTALLATION
4213C SUGGESTED HYDROPHONE MOUNTING ASSEMBLY
The main function of the mounting assembly is to support the hydrophone vertically in the water
and orient it with respect to the bow of the vessel. See Figure 2-1 for Hydrophone dimensions.
Mount it at reasonable distance from the vessel's hull and below the level of the keel. The mounting should be rugged enough to withstand the expected forces during the planned operation, and
easy to raise and lower. The type and size of the mounting recommended for the BATS Hydrophone varies with the size of the surface vessel and the intended application.
Transiting to/from operating locations with the hydrophone deployed is not recommended.
In general, consider the following when designing the hydrophone mounting.
1.
The mounting pipe should be long enough to position the hydrophone below the vessel keel when in the vertical position.
2.
The pipe used should be stiff enough to prevent vibration or strumming when the
vessel is underway.
3.
Attach the pipe to the side of the vessel so that the pipe and hydrophone assembly
can be easily removed and set on board, if required, to tie the vessel up alongside
other vessels or at dockside.
4.
The entire assembly should be easy to raise and lower with available manpower or
winches.
5.
Hydrophone heading (referenced by the index mark) should align with vessel heading. The mount should be fabricated to allow the rotation of the hydrophone to correct for any bearing misalignment during installation (see section 2.4.1 Bearing Offset Adjustment). Some locking arrangement should be used to maintain the calibrated bearing.
6.
Forward and aft guys are used to hold the mounting pipe in vertical position.
See Figure 2-2 for example of mounting arrangement.
The Model 4213C Hydrophone can be mounted to an angle bracket which mounts to the end of a
suitable length of pipe or assembled into a machined end of pipe or shaft. Choose the size and material of the pipe according to the application. The Hydrophone can survive up to 10knots as long
as shaft/pipe does not strum or vibrate.

BATS AND PORTABLE BATS
2.1.2
INSTALLATION
ATTACHING HYDROPHONE TO ANGLE MOUNT
The hydrophone centerline, or zero bearing, is indicated by the index mark (mark is just above the
potted section of the hydrophone which is aligned with the slot in the pressure case as opposed to
the pin which faces aft or 180 from bow reference) and is generally aligned so that it corresponds
to the vessel heading. Most operations requiring a portable tracking system will be on various vessels of opportunity, and require a quick and temporary mounting. See Figure 2-2 and 2-3 for a typical hydrophone mounting arrangement.
Fasten the hydrophone, Model 4213C, to an angle bracket (not supplied), (see Figure 2-4 Hydrophone Mount Angle Bracket, 4213BM0010 as an example) aligning the slot in the PVC base with
the “V” in the bracket. Using screw clamps secure the hydrophone to the proposed angle bracket.
Align the screw clamps with the grooved areas on the hydrophone case.
Feed the deck cable, Model 4113C or 4113C-DT, through the hydrophone extension pipe.
Connect the deck cable to the hydrophone. See Figures 2-5 and 2-6 for the Model 4113C and
4113C-DT cable assemblies.
The Deck Cable mates to the Hydrophone by lining up the pins in both connectors and pushing together. The mated connection is then held together with the locking sleeves. The following are
guidelines from the manufacturer.

Align indexes on connectors and mate with minimum twisting and flexing

Care must be taken not to damage contacts in unmated connectors

Contact surfaces must be dry prior to mating.

Lubricate mating surfaces with 3M Silicone Spray or equivalent* (see caution below). DO
NOT GREASE. Connectors must be lubricated on a regular basis.

Avoid contact with solvents.

Grip main body of connector during mating or unmating. Do not pull on the cable to disconnect.

Avoid sharp bends at cable entry to connector.

Elastomers can be seriously degraded if exposed to direct sunlight or high ozone levels for
extended periods of time.

BATS AND PORTABLE BATS
INSTALLATION
CAUTION
* When mating connectors DO NOT allow any silicone spray (or grease) to contact the
black potting of the hydrophone.
Should silicone come in contact with the hydrophone
potting, proper sound transfer from water to hydrophone will be prevented. Attempting to
remove silicone from the hydrophone can damage the potting material.
NOTE:
If you are using an extension pipe with a sufficient inside diameter to allow the hydrophone cable to be fed through to the hydrophone, remember to run the cable through the
pipe before placing the 1/2-inch (13-mm) bolts in the mounting holes, as the connector
may not pass through when the bolts are in place. When drilling the lower hole, keep in
mind that you need enough space between the end of the pipe and the connector on the
top of the hydrophone itself to connect and disconnect the cable. For this reason, we recommend that the lower mounting hole be no more than two inches (5 cm) from the end
of the pipe.
Fasten the hydrophone and angle bracket to the extension pipe. Use screw eyes or other fasteners
for fore and aft guy attachments.
Using the "V" of the angle bracket as a guide, align the hydrophone (mark is facing forward) with
the vessel centerline as closely as possible. Lock in place.
Use some variation of the procedure in 2.4.1 to remove hydrophone bearing offset.

4213C-B SUGGESTED MTG FOR SEALED SHAFT INSTALLATION
The Model 4213C Hydrophone can also be installed through a hull mounted gate valve. The hydrophone is first installed in a mounting staff and the mounting staff is projected through a gate valve.
This allows for ease of deployment, recovery and maintenance of the hydrophone. Figure 2-7
(4213CM0053) shows the suggested machining dimensions necessary for mounting the hydrophone to an extension shaft (Flanged). An example of a gate valve type mounting arrangement for
Hydrophone installation is shown in Figure 2-8 (4630CM0154). A complete installation is shown in
Figure 2-9. For information on the Model 4630D Motorized Gate Valve System contact EdgeTech.
NOTE:
The slot opposite the “BOW” alignment mark in the staff is for the AFT alignment pin.
The hydrophone extension shaft must extend the hydrophone far enough from the nearest reflector, allowing the direct arrival of a signal from the acoustic source before a reflected signal arrives.
This distance is a minimum of 1 meter. It is also important to keep the hydrophone below the level
of the ship's keel for good 360 degree coverage.
When designing the hydrophone mount/deployment system keep in mind that the shaft be keyed
to allow a repeatable bearing orientation. This ensures that the bow reference always returns to
the same fixed position when the hydrophone is deployed.
The gate valve/mounting staff assembly should be installed in as close to a vertical position as possible.
The hydrophone mount can be installed offset from the centerline of the vessel. An X and Y offset
can be input to the PC to correct for these offsets. Refer to section 2.4.
The Deck Cable mates to the Hydrophone by lining up the pins in both connectors and pushing together. The mated connection is then held together with the locking sleeves. The following are
guidelines from the manufacturer.


The SYNC connector on the BATS Transceiver allows input of an external trigger source and also
outputs a Sync pulse on each interrogation. For example, a tow fish responder that triggers the
beacon can also trigger the Transceiver to Sync the two units together. Also, a responder on an
ROV can be triggered via the differential signal at the SYNC connector. See Figure 2-13 for
connections and Figure 2-14 (4450BA0079) for the provided cable assembly. The mating connector
is a MS3106A-20-29P.
2.2.8.1

with the COMMON line. See Figure 2-13. The Trigger_Out4 and /Trigger_Out4 can be programmed
within the Peripheral Interface Card to either output a trigger or connect it to GND. The Gnd connection can then be used to reference any of the pos or neg triggers for single ended operation.

BATS - ANALOG SENSOR INTERFACE
The ANALOG input connector allows input of an analog signal from a compass, dynamic motion
sensing system, (analog pitch and roll signals from an external sensor such as the EdgeTech Model
4414B), and also the depth signal from an underwater vehicle. An interface cable is provided,
4410BA0123, for inputting analog pitch and roll sensors to the BATS. See Figure 2-15 for
connections and 2-16 for the 4410AB0123 cable Assembly. The mating connector is a MS3106B24-5S from Amphenol. The 4760B MRU uses this interface to provide +12VDC to the unit while the
RS232 connects to COM #3.

DEPTH INPUTS
The analog output voltage from a depth sensor (typically located on a vehicle being tracked) connects to the ANALOG input connector located on the rear panel of the Transceiver. See Figure 1-4.
The BATS converts this analog voltage (0 - 6 VDC maximum) to a target depth.
2.2.9.2
ANALOG COMPASS INPUT
The analog output voltage from a compass (0 - 6 VDC maximum) connects to the COMPASS input
of the ANALOG connector. See Figure 2-15. The BATS converts this analog voltage to a vessel
heading in degrees.
2.2.9.3
VRU INTERFACE (MODEL 4414B)
The VRU input of the ANALOG connector accepts PITCH and ROLL analog signals from an external
dynamic motion sensing system, such as the EdgeTech Model 4414B. The pitch and roll signals
compensate target position for vessel motion. The analog inputs can accept voltages up to +/-10
VDC. See Figure 2-16 for supplied cable assembly. The normal vessel motion for a positive Voltage
pitch is BOW UP and the normal vessel motion for a positive Voltage roll is PORT UP. The polarity of
the analog input signals to the Transceiver can be reversed and compensated for in the REMOTE
VRU POLARITY menu. Normal polarity for pitching bow up is (+) and for rolling port side up is (+).
The VRU scaling can also be modified under the REMOTE VRU SCALE menu. Normal scaling LINEAR
is 0.2 V/degree (+/- 10VDC = +/-50°). (optional scaling is 10 sin )
NOTE:
For a Remote VRU the normal voltage polarity for pitching BOW UP is [+]. The normal voltage polarity for rolling PORT UP is [+]. The system configuration software
(Trackman) shows the roll and pitch polarity [+] when the vessel pitches BOW UP or
rolls PORT UP. The RS232 Format STD W/PR (standard format with pitch and roll at
end of data string) also outputs data with this same protocol. The RS232 Format
NMEA ORE (NMEA 0183 type format string that is proprietary to EdgeTech and includes pitch and roll data at end of string) is different in that it outputs data in the
same polarity as its incoming voltage. This allows pass-through of signals from remote VRU to integrated navigation system without modification of polarities.
When using the Model 4730B VRU setup the Attitude Sensor for Internal. This automatically sets up the parameters to agree with this standard EdgeTech sensor.
Connect the pitch signal to pin-L and the roll signal to pin-S. Connect the analog commons to pinsP & R respectively.

PORTABLE BATS TRANSCEIVER
The Portable BATS Transceiver (Model 4461A) is splash proof when the case cover is closed and
interface cables are mated properly. A laptop or PC is required to interface to the unit via Ethernet
port. The Ethernet cable (4450BA0133) provided is 16 feet (5m) long (Figure 2-13). Make sure the
laptop or PC is well protected unless it is also splashproof.
The Portable BATS requires the following inter-connections along with a suitable power source and
free access for connecting the interface cables. All interface connections are made on the right side
of the unit via underwater connectors. See Figure 1-6. The ON/OFF switch and fuseholder are also
located on same panel. The system LED’s are located under the top cover. Once setup has been
completed (setup LED’s have been confirmed) the cover can be closed and the unit is extremely
splash proof.
The unit can accept input Voltages ranging from 100 to 240VAC, 50-60 Hz, and automatically
switches between the ranges.

The VRU input of the ANALOG connector accepts PITCH and ROLL analog signals from an external

and roll signals compensate target position for vessel motion. The analog inputs can accept voltages up to +/-10 VDC. The normal vessel motion for a positive Voltage pitch is BOW UP and the normal vessel motion for a positive Voltage roll is PORT UP. The polarity of the analog input signals to
the Transceiver can be reversed and compensated for in the REMOTE VRU POLARITY menu. Normal
polarity for pitching bow up is (+) and for rolling port side up is (+). The VRU scaling can also be
modified under the REMOTE VRU SCALE menu. Normal scaling LINEAR is 0.2 V/degree (+/- 10VDC

NOTE:
For a Remote VRU the normal voltage polarity for pitching BOW UP is [+]. The normal voltage polarity for rolling PORT UP is [+]. The system configuration software
(Trackman) shows the roll and pitch polarity [+] when the vessel pitches BOW UP or
rolls PORT UP. The RS232 Format STD W/PR (standard format with pitch and roll at

INSTALLATION
HYDROPHONE OFFSETS
The BATS computes range and bearing relative to the hydrophone, unless the system is instructed
to add or subtract corrections (offsets) which relate range and bearing to some other reference
point on the vessel. The hydrophone centerline, or zero bearing, is indicated by the index mark
(see Figure 2-1, 2-2 & 2-3), and is generally aligned so that it corresponds to the vessel heading.
It is difficult and time consuming to fabricate a mounting in which the hydrophone heading is
aligned to within a degree of the vessel centerline, unless the vessel is in drydock. If you have the
facilities to perform an exact mechanical alignment, or if the installation is to be permanent, consider fabricating a mount that repeatedly returns the hydrophone to the same physical location
aligned to within 0.5 degrees of the vessel centerline.
Most operations requiring a portable tracking system will be on various vessels of opportunity, and
require a quick and temporary mounting. In this case align the hydrophone with the vessel centerline as closely as possible. Use some variation of the following procedure to determine hydrophone
offsets.
2.4.1 BEARING OFFSET
The bearing offset must be determined before X, Y and Z offsets can be measured.
1.
Measure the distance (d) from the vessel centerline to the hydrophone location as shown in
Figure 2-25.
NOTE:
Almost all vessels have a centerline weld or plank that runs down the deck that can
be used for alignment purposes. If your vessel has a seamless deck, you have to
measure the vessel beam and determine the true centerline.
2.
Weight a line to suspend the acoustic tracking source vertically in the water.
3.
As far forward on the vessel as possible, hang the weighted acoustic beacon over the side at
the same distance from the vessel centerline as the hydrophone. (position B1 in Figure 225.) It may be necessary to use a length of pipe or a boathook to extend the weighted line
the required distance. The beacon should be slightly deeper than the hydrophone.
4.
Turn the System on and set it up to track the beacon in use. If you have aligned the mounting bracket correctly, the system tracks the beacon at or very near a 0.0-degree bearing.
5.
If you have designed a mounting that can rotate while in the vertical position, you can rotate the hydrophone until you obtain the correct reading. If you cannot rotate the pipe it will
be necessary to enter a bearing correction at the time of operation. Bearing Offset can be
entered under the USBL HYDROPHONE PARAMETER menu.
2-46
BATS AND PORTABLE BATS
INSTALLATION
The bearing value is the number of degrees that you need to add or subtract to the displayed target bearing to bring it to 0.0 degrees.
For example, a minus 5 degrees would
subtract 5 degrees from the target (beacon) bearing while a positive 5 degrees would add to
the present target bearing. See Figure 2-26.
6.
To check the bearing value determined in step 5, take the weighted beacon line to the stern
of the vessel and again hang it straight down at the same distance from the vessel centerline as the hydrophone (position B2 in Figure 2-25).
The target bearing should now be 180 degrees on the Trackman display.
7.
A further cross check can be performed by taking the weighted beacon to a position directly
across the vessel from the hydrophone (position B3 in Figure 2-25). The target bearing display should now read either 090 or 270 degrees, depending on which side of the vessel the
mounting is located.

2.4.2 HYDROPHONE X AND Y OFFSETS AND HYDROPHONE DEPTH
Hydrophone Offsets are used to reference the target position to the pitch / roll center of the vessel
and also to correct for the hydrophones dynamic motion. Hydrophone motion is due to the pitching
and rolling of the vessel when it is not on the pitch or roll center of the vessel. ( It is assumed the
hydrophone is rigidly mounted to the vessel. ) The hydrophone, when mounted offset from the
vessel’s pitch / roll center, swings in an arc about the pitch / roll center causing variations in the
hydrophone depth, X and Y offsets as the vessel experiences dynamic motion. These variations
cause the target to appear at a different depth, depression angle and bearing than it actually is.
By entering in X, Y and Z offsets the system can correct for this dynamic motion if a survey grade
Motion Sensing System is interfaced to the BATS. See EdgeTech Model 4414B Motion Sensing System. Connect the analog outputs from the Motion Sensor to the rear panel Gyro/VRU input connector.
Hydrophone X and Y offsets are entered with respect to the pitch / roll center of the vessel. ( It is
assumed that the vertical reference for the pitch / roll center is the water-line of the vessel or the
entered “DEPTH OFFSET”. )
NOTE:
The Trackman Software outputs the target position (X & Y) with respect to the pitch
/ roll center of the vessel graphically in the Display, numerically in the Status Block
and also on the RS-232 serial communications port.
In Figure 2-26, horizontal distance and bearing (X & Y) for the beacon are determined relative to
the pitch / roll center of the vessel (C). (Note that the slant range remains relative to the Hydrophone.) Determine the Hydrophone X and Y offsets as follows:
A.
Measure the distance between the hydrophone (H) and the pitch / roll center of the vessel
(C) in terms of X and Y coordinates on a horizontal plane at water level.
The X coordinate is the distance perpendicular to the centerline (dx H in Figure 2-27). The Y
coordinate is the distance parallel to or along the centerline (dyH in Figure 2-27).
Distance along the X-axis from the centerline towards a starboard direction has a positive
value. In this example, the X offset is 7 meters. Distance towards the port side of the vessel has a negative value.
The hydrophone's distance along the Y-axis, forward of the pitch / roll center, is a positive
value. In Figure 2-27, the hydrophone is aft of the pitch / roll center, and the Y offset is -10
meters.
B.
Enter the offsets at the Trackman and observe the display to verify that the hydrophone is
being offset in the proper directions. Figure 2-27 illustrates the tracking window display as
the X and Y offsets determined above are entered.
2-50
BATS AND PORTABLE BATS
INSTALLATION
The hydrophone is represented in the tracking window by a small H. Note that the H shifts
to the right along the X-axis when the positive X offset (7 meters) is entered. The H moves
down, parallel to the Y-axis, when the negative Y offset (-10 meters) is entered.
The target continues to be tracked and now displays X and Y data in relation to the pitch /
roll center of the vessel.
C.
Hydrophone Depth is the depth of the hydrophone below the surface of the water. (Refer to
Figure 2-27.) Depth is entered as a positive value.
The BATS is ready for operation when the hydrophone is in position and the necessary offsets have
been determined, and the acoustic sources to be tracked are active and in the water.
NOTE:
If a pinger is at a depression angle of less than 20 degrees, the measured depression
angle and, therefore, the horizontal range of the beacon are impossible to measure
accurately. Consequently, the bearing of the source, relative to some offset position,
is impossible to determine. If this combination of circumstances occurs (pinger; depression angle less than 20 degrees; and hydrophone offsets entered), BATS ignores
the entered X and Y offsets so that it can display a correct bearing relative to the hydrophone. Refer to section 3.6, error code 51.

2.4.3 HYDROPHONE-VRU OFFSET
The VRU offset is the difference in angle between the installed hydrophone and vertical (static offset). (It can also represent the offset between the Remote Dynamic Motion Sensor and the Hydrophone.) Offsets can occur either due to a mis-aligned hydrophone or from changes in trim to the
vessel. The system allows for either manual entry of attitude error corrections or auto correction
via the hydrophone's internal VRU for offsetting the static tilt of the hydrophone/staff. The attitude
(pitch/roll) offsets are error constants that subtract from the remote or external dynamic motion
sensing system data to compensate for the non-vertical installation of the Hydrophone shaft (or
difference between DMS and Hydrophone).
ENTERED OFFSETS: For manual entry the operator must measure the angle of the shaft with respect to vertical and enter the data in the PITCH-ROLL ERROR menu. The vessel should be in a
harbor or at dock to perform this measurement. Pitch and roll errors are entered in degrees. The
system accepts and displays data with a precision of 0.01 degrees.

4740A
VRU/Amplifier is mounted on a surface other than bow facing. For example, if the arrow at the top of the

program. The Trackman program automatically sends the previously setup system and target parameters to the Transceiver upon start-up4. The Transceiver returns the status of the system and it
is displayed on the screen. (Also, see “Get BATS Config” under SETUP menu). In a rack mount configuration supplied by EdgeTech, if the power is removed from the unit, the PC automatically starts
and boots into the TRACKMAN program without operator intervention upon return of power.

It takes approximately 35 seconds for the Transceiver to boot-up. Wait at least 30 seconds after
booting the PC before setting parameters within TRACKMAN.

NOTE: The Hydrophone calibration data is used by the Trackman software. A set of calibration files
(included with every Hydrophone) is copied into its directory. Changing of the Hydrophone requires
that the two files that comprise the calibration factors be installed into the Trackman PC’s folder;
C:\Program Files\ORE Offshore\Trackpoint MMI\CalFiles\InUseCAL\.
The BATS Transceiver, Model 4460C, front panel is shown in Figure 3-2. The front panel contains

“TRACKMAN” SOFTWARE PHILOSOPHY
I know from experience that sometimes you can just run a program and everything seems intuitive
from the start. Other programs you struggle through and nothing makes sense as far as the menu
structure. I am going to give a brief overview of our design philosophy and how and why it was developed this way. So, when you are plucking through the menus saying to yourself “What was that
person thinking?” maybe this will help! If not, send us an email. Criticism accepted! This software
has been designed and tested on various computers and operating systems. It can run under Windows® 95, 98, ME, NT, 2000, and XP. Even given all our testing, I am sure there are some combinations of hardware and software that will cause some quirks in its operation, but for the majority
of machines it is stable. See section 2 for recommended hardware and operating systems.
The “Trackman” (originally TrackPoint Data/Control Manager) software evolved from EdgeTech’s
earlier TrackPoint II USBL system. It was designed to allow an interface between any of our new or
future USBL products. It also has a means to communicate with Navigation software (e.g., IPS) on
the same PC using UDP or TCPIP, that is sending the USBL data to a software port and having the
Navigation software read it directly without having to go through hardware ports. This Trackman
program can then be hidden6 (minimized) once the USBL System has been setup and the Navigation software run as the primary display. See SETUP menu. The basic menu structure is shown below.
 File Menu

Various Help Topics
There is a feature (“Update While Hidden” function) that allows the Trackman software to not up-
date the plotting while hidden (minimized). This saves a lot of processing power for use in other
programs such as the Integrated Navigation programs. Trackman’s main function is then to just
collect and process data and pass it on to an Integrated Navigation Software package.

Jobs: Stores all the setup parameters to a “Jobs” folder/file.
Project Tree: A Project Tree was developed as a graphical view of the parameters that normally
would change via the standard menus. It is a drag & drop window that can move or be hidden. The
Computer icon is shown at the top as the primary unit. This is the hardware platform that runs this
software. Under the Computer are it peripherals, display, disk services, printer, etc. The Device List
shows in a table7 all the peripheral ports that communicate with the PC including the USBL System
(BATS). A device can be any peripheral associated with the USBL System. It can communicate via
its serial ports or TCP, UDP or UDP Broadcast. The Data Output icon brings up the same Device table but goes directly to the Device output line within the table. Just click on the line or hit Enter
and the setup dialog box is displayed to allow setup of a port to output the tracking data. (We
could have left this out and just showed the Device List but felt this brings attention to the operator
to make sure the Data Output port is setup for the job.) The “to USBL Interface” is only for graphical representation of a port going to a USBL device (COM port). The “BATS” is only for graphical
representation of the Transceiver. Under the “BATS” are the items associated directly with it. It
shows the typical items that the operator should setup for USBL operation; GPS/TimeSync (format
of data input), Hydrophone parameters, Acoustic Data (Speed of sound in water, temperature,
etc.). The GPS is used for time syncing only. It does not reference the data to Latitude /Longitude.
Typical ZDA or GGA sentence received uses the first character in sentence as the sync pulse for the
time received in the sentence. This sets the clock within the Transceiver to better than 50ms accuracy. The time that is on each beacon’s output sentence is the time that each reply was received.
Sensor Setup: This is a system input setup dialog. Sensor inputs can be either from Heading Sensor (an analog or serial input to the Transceiver or serial only to the PC) or an Attitude Sensor (internal to BATS Hydrophone if applicable or a remote analog sensor input to the Transceiver or
NMEA into either USBL or Trackman PC).
Beacons: Clicking on the Beacon(s) icon brings up a table for beacon entry. It also provides a
quick view of the Beacon parameter settings. Click on any line within the Beacon Setup Table to
bring up its dialog setup box.
ORE ICON: Right clicking on the ORE icon on the task bar brings up a menu to allow closing of
Trackman, showing the About box, or disabling the screen saver. For example, disabling the screen
saver can be useful when tracking your ROV and the screen saver decides to start the starfieldR
display just when you are trying to see where your ROV is with respect to the boats prop! Click on
“Disable Screen Saver” to prevent screen saver from turning on.

within
Trackman is an ActiveX module. Internal
to Trackman it is called the “TrakComX”
module (TrakComX.ocx). It is used for
communication
with
various
"devices"
over Serial (COM) Ports or TCP_IP Sockets. Each "device" (BATS, depth sensor,
compass, gyro, GPS, etc.) that Trackman
connects to creates a 'copy' of TrakComX for that "device". (See Technical Note below.) A “Status
Block” for each of the devices is shown in the lower right corner of the screen (Trackman Status
Bar). It shows the Device number along with a simulated “LED” that blinks with the input or output
of data. For example, two of these are shown above, one for “device” 1 and one for “device” 4: The
two small green rectangles on the right side of each window act as transmit and receive indicators
(left is transmit, right is receive) that ‘flash’ to indicate activity. The yellow background behind a
number indicates an error has occurred on that device. Left-clicking on the number brings up the
Error/Data Viewer window which can be used to display a running list of errors of the received data. Putting cursor over the

BATS AND PORTABLE BATS
OPERATION
Technical Note:
A software function within Trackman called TrakComX (aka a 'WinPort'), handles both Serial Ports
and Sockets, each WinPort can handle a single Serial Port or Socket. Due to hardware constraints
in Windows, if a Serial Port is already in use by an existing copy of WinPort an attempt to create a
new copy using the same Serial Port will fail. This means that two copies of WinPort can NOT share
a Serial Port!
Unfortunately, since many of the "devices" that we want to connect to are in fact individual pieces
of hardware, they often share a common serial or network "bus" with many different style packets
from the different "devices" running down the same wire. This means that some of the different
"devices" we are trying to connect to may be on the same Serial Port such that if we were to try
and use a separate copy of WinPort for each copy of TrakComX on that Serial Port all but the first
one will fail.
Our way around this is to manage a 'pool' of WinPorts that allow copies of TrakComX, that require
the same Serial Port, to share a copy of WinPort. Each time a TrakComX copy is created, the "pool"
is checked to see if an existing copy of WinPort is already handling the new TrakComX copy's desired Serial Port, and if so, the existing WinPort is 'shared' by the new copy of TrakComX.

“TRACKMAN” MAIN WINDOW
Application Overview
The TrackMan Windows application provides a user-friendly interface for managing the EdgeTech
BATS or BATS Portable USBL (Ultra Short Base Line) underwater navigation systems.
The interface to the BATS is via the Ethernet port. Other peripherals (Compass, Motion, or Depth
Sensors) may connect via a COM (serial) port connection or a TCP/IP socket. This interface is handled by the TrakComX ActiveX control internal to Trackman.
From the application, the user can enter parameters by clicking on items displayed on a convenient
tree diagram (the Project Tree) on the left side of the main screen. Data is displayed in one or
more MDI child windows, such as the Plotting Grid, on the right side of the main screen.
If the application is being used only as an interface between BATS and another navigation application, it can be hidden from view via a left-click on the Tray Icon (the ORE icon in the System Tray
area at the right end of the Task Bar). When hidden, a left-click on the Tray Icon will bring it back
into view. Right-clicking the Tray Icon brings up a menu providing the ability to disable the screen
saver, view the About Box, or close the application.
From the PC, start the Trackman application by navigating to the Program Folder [TrackPoint
TRACKMAN] and clicking on the TrackMan application button. The main window is displayed. See
figure below. It shows the Project Tree diagram on the left. The tree provides quick access to various configuration information. Clicking on most items will pop up a dialog window associated with
that item.
Trackman starts running the previous “Job” that was saved. The Trackman software is a Windows
based application that provides a remote interface from a PC to the BATS Transceiver providing
target display and data output.
Project Tree Window
The Project Tree Window provides the user with a tree-oriented view of the system. The tree's
nodes indicate the relationships of the various components. Most of the nodes provide direct access
(via the keyboard or via mouse double-clicks) to related setup dialog windows.
Computer Node - This node displays various sub-nodes (Display Options, Disk Services, etc.) that
provide access to basic system services as well as sub-nodes for access to the USBL Interface dialogs.

NOTE: When a target is designated as a Pinger it is the only
target that can be enabled at

A Transponder is an underwater
beacon
that
is
interrogated
(Triggered) acoustically. It usually requires a single frequency or tone at a minimum pulse length
before it will respond with its reply frequency. A Turn-Around-Time must be selected in order for
the system to calculate an accurate slant range. A Responder is triggered electrically. For example,
if tracking an ROV or Towfish, utilize the umbilical cable for sending down a key pulse to fire the
unit. This provides a more stable track as you do not have the jitter in range due to the receiver as
in the Transponder. A Pinger requires that the operator know the repetition interval of the beacon.
Select the interval from the pull down list under reply parameters8.

When tracking a Pinger the system requires an interrogation interval be entered at the same rate
as the repetition interval. The system automatically sets the interrogation interval from the entered
repetition interval.

Reply Frequency Setup Parameters: This is the Reply Frequency of the beacon. Select the Reply Type; CW (continuous wave/tone), Shift (linear frequency shifted, also known as chirp or FM),
Coded (special such as Remus codes), M-FSK (multiple- frequency shift keyed; typical for Model
4370A beacons) and PRN (pseudo random number generated codes).
CW (tone)
The CW waveforms are typical of the ORE legacy beacons, Model 4320 or 4330 series (see note below).
The burst is a single frequency with a typical pulse
length of 1.3ms. Select the frequency in 500Hz increments and the correct pulse length9.
SHIFT
The shift waveforms are a linearly changing frequency
over a specific pulse width. Enter in the start frequency and the end frequency in kHz along with the exact
pulse length in ms. For example, an Edgetech Model
4200 Towfish with responder option produces a waveform starting at 24kHz and ending at 28kHz with a
pulse length of 10.000ms.
M-FSK
These waveforms change frequencies in discrete
steps instead of in a linear progression as in the shifted types. The MFSK codes are shown in Appendix E.
CODED
These are proprietary codes of Hydroid’s REMUS underwater vehicles and transponders. They have specific interrogation and reply PRN type codes.

PRN
Pseudo Random Number codes. These consist of a single frequency but with 180° phase shifts at
various bits within the sequence. Enter the frequency in kHz (in 1 Hz increments), the PRN code in
octal and chip length in micro-seconds increments (minimum chip length is 100.000 microseconds). The PRN code describes the phase shifting pattern. The chip length is the waveform period
times the number of cycles.
Interrogation Parameters: The Interrogation Parameters consist of the Interrogation Interval,
the Interrogation Frequency and Trigger Source.
Select the Interrogation Interval (based on the slant
range to the target) in seconds and the Pulse Width
necessary to interrogate the beacon in milliseconds.
(In high multi-path environments it may be beneficial to decrease pulse width to prevent multiple
triggering of the transponders.) Select whether the
beacon is being triggered internally by the BATS or
by an external source. If external then select the
edge that the BATS should synchronize the timing
with (+) or (-). If multiple targets are enabled then
a specific Beacon can be set as a “Priority” which
alternates interrogations between all the other active targets.
If two or more targets have the same interrogation
frequency/code then the targets will be tracked
simultaneously. If the Interrogation Frequencies are
different then they will be tracked sequentially.

configure the Beacon’s Telemetry parameters. If depth
is via an analog sensor, e.g.,
an ROV or SSS vehicle, then
select “Analog” and then under “Depth Mode Setup” configure the Beacon’s Analog
parameters. The analog port is available at the GYRO connector on the rear panel of the BATS
Desktop or the side panel of the Portable unit. If the target’s depth is available via a serial port,
select “Serial Port” and then under “Depth Mode Setup” configure the Beacon’s Comport parameters. Select the Depth Input sentence, DBS, DBT, PEIV1 or DPT. (See formats below.) This Serial
port is available only at the PC’s serial input not
the Transceiver’s.11
In the TELEMETRY mode the depth is taken from
a depth telemetering transponder. The transponder sends two replies to the Transceiver per
interrogation.
The first reply signal is used to
determine slant range and bearing, while the second reply (whose delay from the first is proportional to depth) is used in the depth calculation.
Given
these
three
parameters
a
three-
dimensional position fix is calculated. The “Telemetry Depth Setup” menu is used in conjunction with “Telemetry Mode”. It contains parameters to allow the operator to change the telemetry

reply frequency, and also to change the zero delay, full-scale delay and span. When Telemetry
Depth is selected, a 'T' appears next to the depth value in the Status Block when the telemetered
value is being used in the horizontal range calculations. If the system is using a calculated 12 depth
then a `C' appears next to the depth value. If the depth telemetry replies are not received, the last
valid telemetry reply is used for the depth. If telemetry replies return, system reverts back to
depth telemetry. If not using a Telemetry Beacon then depth should be changed to Manual or Analog.

 Filtering Tab
The “Filtering Tab” allows each
beacon to have individual filtering parameters, configuring
each beacon for its own tracking scenario. Select Filter Level
for the beacon in use. In the
case of a fast moving target
set the level between 1 and 5
with 1 being for minimal filtering and 5 being for moderate
filtering. For slower moving
targets set level between 6
and 10 with the filtering parameters increasing to maximum at 10. To set limits on
known target locations modify
the Slant Range and Bearing
parameters.
When  OK is selected the Trackman program sends the parameters to the Transceiver. This delay
causes the dialog box to remain on screen for a few seconds following the command.

BATS AND PORTABLE BATS
OPERATION
FILTERING provides operator a choice of various combinations of averaging, filtering, threshold
settings and also limits on certain parameters. Filtering includes averaging, target velocity checking, range gating, signal threshold, minimum xponder range, maximum xponder range and signal
rejection via signal quality checking. The filtering parameters are individual per target.
Filter Level: The Filter Level setting is variable from 1 to 10. A Filter Level setting of 1-5 is recommended for most dynamic applications (e.g., ROV tracking).
The higher settings of 6-10 are
appropriate for static applications such as station keeping. The parameter settings for the range
blanking gate and velocity filter “tighten up” as the Filter Level is increased with the premise that
dynamic targets such as AUV’s can change position quickly with respect to the vessel while static
targets such as a tow fish or other moored targets do not. Filter settings 6-10 cause the analog or
telemetry depth to average the last three readings. Filter settings 1-5 do not average the input
depth. Also see error code #5.
The table below shows the relationship between the range gate, velocity filter and averaging
weight Vs the Filter Level setting.
FILTER LEVEL/RANGE (blanking) GATE (Transponders & Responders Only)
If there is more than one sequential target the range blanking gate value is multiplied by the number of targets (e.g., filter level 2 with 4 targets enabled equates to a blanking gate of 80 meters
before the average target range). If the blanking gate exceeds the current range average then it is
set to a minimum (1m). The range average for each target is weighted based on the number of
good replies for that target. If there are no recorded good replies then the routine uses 100%
weight on the current value and is scaled down for up to 4 replies (e.g., if there have been 4 or
more consecutive good replies each new reply contributes 25% to the average). As replies are
missed, more weight gets added to the new reply. If there are more than 2 missed replies, the
blanking gate opens up by a factor of 2, until we exceed a maximum (currently 4) where it is wide
open.

At the higher filter levels the averaging is almost linear across all replies (up to 1.8:1 depending on
number of replies smoothed) while at the lower filter levels the weight is higher on the most recent
reply (up to 4.0:1 depending on number of replies smoothed). The QF also contributes to the weight
in the smoothing buffer. See chart and also QF FILTERING below.

RANGE GATE AND TELEMETRY (Transponders & Responders Only)
When telemetry is enabled the system also blank-gates on the telemetry reply. On the primary or
navigation reply the Transceiver accepts only the first signal arriving at the hydrophone following
the opening of the blanking gate and ignores signals for  80 milliseconds following it. When the
telemetry gate opens the Transceiver accepts the first signal at the telemetry frequency and all
other signals are ignored until after the next interrogation. This is advantageous when operating in
a high multi-path environment, insuring that the system locks on to the correct reply.
FILTER LEVEL/TIME GATE (Pingers Only)
For pingers the system uses a Time Gating system based on the targets entered repetition interval
instead of the slant range as used in the range gating. Time gating eliminates any unwanted signal
detections that occur at a time when no response is expected. Since the pinger repetition rate is
entered and the reply interval is known, Transceiver can determine, within some short time interval, when the next signal is expected and only allows signals which fall within their time window to
be accepted for further processing. It depends upon accurate entry of repetition rates in the TARGET sub-menu for proper tracking. The time gate is a function that compares the time between re-
3-28
BATS AND PORTABLE BATS
OPERATION
plies against the entered repetition value. It accepts the first reply that arrives in a window 50 ms
prior to the expected arrival of the signal (beginning of time window) and up to 50 ms after the expected arrival. It then ignores replies later than 50 ms after the calculated time gate window. If no
replies are detected within a certain period, an error code #2 is flagged and the window opens up
to find the reply.
FILTER LEVEL/VELOCITY FILTER
Velocity filtering is a technique of rejecting any target position changes that are unlikely due to an
assumed maximum target velocity and elapsed time since last update. It is based on the difference between the previous X and Y position (averaged, if smoothing is enabled) and the present
targets X and Y position. If the present calculated position passes the velocity filter test it is then
sent to the smoothing function. If after a certain period of time there is no reply within the expected area then an error code #5 is flagged and the system opens up to find the reply.
NOTE:
A fast-turning ship can cause the target to appear to be traveling at excessive
speeds and be rejected by the velocity filter, when the compass option is not in use.
SNR Threshold: The threshold setting is normally set to 20dB (default). Raise the threshold if the
system is triggering on noise, usually indicated by erratic slant ranges. Use caution when setting
threshold lower than 20dB. I.e., if you know the approximate position of the target and you want
to get the maximum range then it may be possible to lower threshold in the presence of low noise.
As the threshold level is increased, only stronger signals are accepted, and weak signals, which
could be caused by multi-path or extraneous noise in the water, are ignored. The lowest threshold
setting increases the sensitivity of detection by recognizing smaller signals. In a high-noise environment this can lead to erratic readings. Higher threshold settings decrease the possibility of detecting on noise, but can lead to occasional missed valid signals and also late detections causing
erratic bearings. A lower threshold setting is usually the best choice, but trial will lead to the optimum threshold setting for a given application.
Averaging: The Averaging parameter is variable from 0 (off) to 10. It is independent of the Filter
Level setting in that you can select the buffer size in which to average a number of replies over (110). This setting corresponds to the number of replies that are averaged along with the present
reply. The averaging routine is used in conjunction with the QF (Quality Factor) and the Filter Level. With a high quality factor the target position is weighted heavily both on the present reply and
on the previous replies in the averaging buffer. If the present reply has a high QF and the previous
reply had a low QF then the position with the high QF remains heavily weighted within the averaging buffer. As new replies are received the high QF positions maintain their heavier weight while
the positions with lower QF’s have very little weight. The weights of the target positions are reduced as the newer replies are received. This approach biases the target position towards the better QF and also towards the most recent reply providing a better representation of target position
than by using a mean or average of the target positions. At the higher filter levels (8-10) the aver-
3-29
BATS AND PORTABLE BATS
OPERATION
aging is almost linear across all replies while at the lower filter levels the weight is higher on the
most recent reply. Averaging occurs on the target's position only (X, Y or HD, BRG), not on the
displayed slant range. The slant range displayed in the status block and sent out the RS-232 is the
actual value. Because of this there may be an apparent discrepancy between the displayed position and slant range.
QF Filtering: QF Filtering is a toggle function that turns QF Filtering on or off. The Quality Factor
(QF) is a value (1-10) determined by the system on each reply that is detected. The system uses
the phase or time counts from each of the hydrophone elements to determine the quality of the
signal. If the phase counts are consistent throughout the reply burst the quality factor is very high.
If the phase counts have jitter or are inconsistent then the quality factor is low. The QF FILTERING
function filters the data depending on the Quality Factor of the signal received. It compares the
Quality Factor of the signal received to its previous five (5) average Quality Factors. The QF FILTERING function toggles Quality Factor checking on or off.
This function filters the data depending on the Quality Factor of the signal received. When “QF FILTERING” is “ON” and the Quality factor is less than the average of the last five QF’s the data is not
plotted and causes an error code #4 to be displayed. In this case the error is considered a “fatal”
error (similar to all other error codes under 20) and the reply is not added to the smoothing buffer.
The target position is not updated on the screen and the positional data is not sent out the RS232
port unless the “EC” formats are chosen. If “EC” formats are chosen then a post processing navigation system could be used to determine if the reply was good or bad by searching for a 4 at the EC
location within the data string. When “QF FILTERING” is “OFF” and the Quality factor is less than
the average of the last five QF’s the data is plotted on the screen and sent out the RS232. The data
is tagged with an error code #64 on both the display and RS232. In this case the error is considered a “warning” error (similar to all other error codes greater than 50). The data is still smoothed
but its “weight” within the averaging buffer is decreased. Again, a post processing navigation system could then be used to determine if the reply was good or bad by searching for a 64 at the EC
location within the data string.
Maximum Target Velocity: Select the Maximum Target Velocity (+/-) if using a PRN or Remus
type codes (as they are susceptible to Doppler shift). If the target, for example, is a towfish (which
has very little relative movement between target and Hydrophone) the MTV can be kept at 5 knots
or less. By keeping the MTV below 5 knots the processing load on the Transceiver is minimized.
Target Limits: The Slant Range Limit (Minimum Transponder or Responder Range) function works
in conjunction with the range gating (blanking) system based on the target slant range. The range
(blanking) gate is a hardware lockout that “opens up” and allows signals to be detected from the
hydrophone. The time that the blanking gate opens is based on the Filter Level and the time the
last reply was received. If a condition occurs where the blanking gate end time is less than the
Slant Range Limit’s (from value) then the blanking gate overrides the Slant Range Limit’s (from
value). This in effect locks-out all signals from the hydrophone prior to the end of the blanking
gate. If the system loses tracking due to the Slant Range Limit (from value) being greater than the
3-30
BATS AND PORTABLE BATS
OPERATION
actual slant range from the target the system shows an error code #7 (SR < Min Range). After 5
interrogations without a reply the system opens up the blanking gate and accepts the reply on the
sixth (6th) interrogation (EC #6 may appear briefly prior to reception of signal). If the Slant Range
is less than the Slant Range Limit’s (from value) then the error code #6 is changed to #7. The
Slant Range Limit’s (from value) can vary from 1 to 1000 meters.
NOTE:
If you are operating with a known minimum range, for example with an ROV near the
bottom in 500 meters of water, then the Slant Range Limit’s (from value) could be set
for 450 meters. This would provide an effective "range gate" without the attendant target acquisition and re-acquisition time of the normal range gate. Of course, as you recover the ROV you will have to reset the Slant Range Limit’s (from value) to track the
ROV to the surface.
The Slant Range Limit’s (to value) (Maximum Slant Range) function compares the reply’s slant
range against this value. If the slant range is greater than the entered value the last good reply
remains on the display (target position on the screen doesn’t change) and the status block shows
an error code #14. If the RS232 Format is set to an “EC” format it also outputs the last good position and tags it with an error code #14. The Slant Range Limit’s (to value) can vary from 0 m
which is OFF to 10 to 10000 meters.
The BEARING LIMIT function is a final check after the range gate and velocity filter are satisfied.
The system checks to see whether the target is within the parameters as set by the bearing limits.
This function is only applicable to targets with a depression angle of less than 45. If a target is
outside the set limits then the system displays an error code #15, "BEARING LIMIT EXCEEDED".
The system does not update the target on the screen but the data is sent out the RS232 (when an
“EC” format is selected) with the fatal error #15 attached to the string. The limits are always referenced to the vessel, whether compass mode is ON or OFF. The default values for the bearing limits
are 0 to 0, which disable the function.

TCP/IP & UDP Protocols
The global network we all know as the Internet
transfers information between computers using a
protocol (a set of rules) known by the acronym
TCP/IP which stands for Transmission Control Protocol/Internet Protocol.
All Internet transfers use IP (Internet Protocol) as the basic underlying method of 'packaging' data
to be transferred.
Above that underlying packaging 'layer' of operation there are two general methods of transferring
data.
The first method, which is the one most of us know from 'surfing the Web', involves making a
point-to-point connection when transferring data. This point-to-point connection uses the TCP
(Transmission Control Protocol) part of TCP/IP. It's a lot like making a phone call, when the other
person answers the phone your connection is acknowledged and you can transfer data back-andforth (talk) point-to-point.
The second method, called a datagram or connection-less interface, is a simple 'pack it up and ship
it out' technique that essentially works like mailing a letter. With a datagram you don't make a
connection with the receiver, you simply send your data and assume that it will get where you're
sending it. In the Internet world a protocol known as UDP (User Datagram Protocol) is used to
transfer data in this way.
One of the advantages of UDP is that you can send data to more than one receiver at a time since
there's no need to establish a point-to-point connection. This technique is known as UDP broadcast
mode. Using UDP broadcast mode an application acts much like a radio station, it broadcasts data
on a specific IP port and anyone who wants to 'listen' to the data 'tunes in' to that port. There's no

need to make a point-to-point connection so there's no connection to break when a listener stops
listening.
Normally, the Trackman is the “CLIENT” while the software you are connecting to is a “SERVER”. If
the interface software13 requires that Trackman be a SERVER then click on the check box below the
IP Address.
The Sentence Output from Trackman is the data format sent from the PC to the Navigation

OPERATION
Setup  Attitude Sensor Setup
This is the System Level Attitude Sensor setup. (Same
as clicking on the Attitude Sensor line in the Project
Tree.)
The pitch and roll signals compensate target position
for
vessel
motion. The analog inputs [Trackpoint
(USBL)] can accept voltages up to +/-10 VDC. The
normal vessel motion for a positive (+) Voltage pitch is
BOW UP and the normal vessel motion for a positive
(+) Voltage roll is PORT UP. The polarity of the analog
input signals into the TP3 can be reversed and compensated for in the USBL ATTITUDE SENSOR POLARITY
dialog box. Normal polarity for pitching bow up is (+)
and for rolling port side up is (+). The VRU
scaling can also be modified under the USBL
ATTITUDE SENSOR menu. Normal scaling is
0.2 V/degree (+/- 10VDC = +/-50°). This dialog also allows the selection of the Compass
Sensor Input to be either from Trackman (PC)
or (TrackPoint (USBL)).
NOTE: For a Remote VRU the normal Voltage
polarity for pitching BOW UP is [+]. The normal voltage polarity for rolling PORT UP is [+].
The RS232 Format STD W/PR (standard format with pitch and roll at end of data string)
also outputs data with this same protocol. The
RS232 Format NMEA ORE (NMEA 0183 type
format string that is proprietary to EdgeTech
and includes pitch and roll data at end of
string) is different in that it outputs data in the
same polarity as its incoming voltage. This allows pass-through of signals from remote VRU
to integrated navigation system without modification of polarities.
For the Trackpoint (USBL) “BATS“ there are three types of Attitude Sensors that can be interfaced to the system are; Internal, Analog or Serial.
The INTERNAL selection is not valid with BATS at this time.

Setup  Compass Setup
This is the System Level Heading sensor setup. (Same
as clicking on the Heading Sensor line in the Project
Tree.)
The heading data can be set to off (None), Grid Only,
Data Output Only or Both Data Output and Grid. If for
example, the Navigation System was to correct for
compass heading and not BATS then set the North Reference to Grid only. The RS-232 data would not be corrected for North but the Target position on the grid
would be.
The Compass Correction can either be…


Data O/P Only
Grid Only
Both Data O/P & Grid
Enter in the magnetic variation in degrees.
This dialog also allows the selection of the Compass Sensor Input to be either from Trackman
(PC) or Trackpoint (USBL) (BATS Transceiver).
Clicking on the “TrackPoint (USBL)” button brings
up the “USBL Heading Sensor (Compass)” dialog
box. Select None (to turn off) or the interface required, either Analog as input to the BATS Transceiver’s SYNC connector located on the side panel
or the Serial port which accepts NMEA compass
sentences. The Serial input goes into the DB-9
COMMS connector located on the side panel also
of the Portable or rear panel of the Desktop.
When the compass is enabled (either Analog or
Serial,
Trackman
(PC)
or
TrackPoint
(USBL)
Transceiver), the RS-232 target position data is
automatically switched to north referenced. This means that the target data (bearing, X, Y) output
to the RS-232 port is referenced to North instead of the bow of the vessel. The operator can override this by selecting Compass Setup from the main Setup Menu. Click the pull-down menu of the
dialog box and select where the Compass Correction should be applied; None, Data O/P Only,
Grid Only, Both Data O/P & Grid. The “Grid Only” function is used in situations where Trackman

BATS AND PORTABLE BATS
OPERATION
is interfaced to a navigation system and the navigation system already interfaces to a heading sensor such as a flux gate compass or gyro-compass. In this case, the Trackman’s RS-232 data does
not need to be corrected for North reference. However, Trackman requires a compass input to
compensate for vessel motion within its filtering algorithms. By selecting “Grid Only“ the target data on the Trackman screen remains referenced to North while the RS-232 data is referenced to the
bow of the vessel thus allowing both Trackman and the navigation system to function properly. To
have the Trackman Heading correction applied along with the RS-232 Data Output then select
“Both Data O/P & Grid”.
NOTE:
When the Compass Correction function is set to “Grid Only”, the RS-232 data is averaged (when smoothing is enabled). However, the positional data on the Trackman
display is only smoothed or averaged prior to the target’s compass correction resulting in positional changes directly related to the change in compass heading. When
the Compass Correction function is set to “Grid Only” the target position is averaged
after the compass has corrected the data for North Reference resulting in a more
“smoothed” target position on the Trackman screen.
Analog: For the Analog Heading Sensor electrical interface see Installation, Section 2 above. The
Transceiver converts the analog Voltage to a ship’s heading in degrees.
In the “Zero degree Voltage” box enter the minimum Voltage that corresponds to zero degrees.
(Range 0 - 5.99VDC) In the “360 degree Voltage” box enter the maximum Voltage that corresponds to 359.99 degrees. (Range 0.1 - 6.0VDC)
When in analog compass mode the heading data is displayed at the top left of the screen and has a
suffix “A” attached to indicate that the data is from the analog input.
Serial: See section 2 (Installation) for wiring
the compass to the Transceiver COMMS connector. Click on “Port Settings” to select the
TrackPoint (BATS) Transceiver comport that the
compass connects to. (COM2 or COM3) Set the
baud rate, Parity, Data Bits and Stop Bits to
agree with the compasses serial port protocol.
Refer to section 2 for COM Port wiring for the

The following describes the format of each of the NMEA and the TCM-2 compass sentences. If the
“Use Checksum” is checked, and the checksums do not agree, the data is ignored. If the “Use
Checksum” is not checked then the data is accepted even if the checksum does not agree or is
missing from the string. (The checksum is the 8-bit exclusive OR (no start or stop bits) of all characters in the sentence, including “,” delimiters, between both, but not including, the “$” and the “*”
delimiters.) On the RS-232 target output data sentence there is no compass heading identifier to
distinguish between True and Magnetic heading information except on the NMEA ORE format.
The Heading data is continuously received from the Transceiver’s ComPort but only updates when a
valid target has been detected. The Model 4460B can accept heading information at data rates up
to 100Hz and baud rates up to 115.2k.

USBL  Hydrophone
From the USBL main menu select Hydrophone to bring up the USBL Hydrophone setup parameter
dialog box.
Hydrophone
Offsets
are
used to reference the target position to the pitch /
roll center of the vessel.
The system uses the hydrophone offsets to reposition the target with respect
to the pitch/roll center of
the vessel and also to correct for the hydrophone’s
dynamic
motion.
Hydro-
phone motion is due to the
pitching and rolling of the
vessel when it is not on the
pitch or roll center of the
vessel. ( The system assumes the hydrophone is rigidly mounted to the vessel. ) The hydrophone, when mounted offset
from the vessel’s pitch / roll center, swings in an arc about the pitch / roll center causing variations
in the hydrophone depth, X and Y offsets as the vessel experiences dynamic motion. These variations cause the target to appear to be at a different depth, depression angle and bearing than it
actually is. By entering in X, Y and Z offsets the system can correct for this dynamic motion if a
survey grade Motion Sensing System is interfaced to the BATS. See ORE Model 4414B Motion
Sensing System or Model 4760B.
At the time of installation, the hydrophone should have been oriented as nearly as possible in parallel with the centerline of the ship, and any remaining bearing offset determined (Refer to section
2).
Bearing Offset: The Bearing Offset is the rotational offset between the hydrophone’s acoustic zero-degree line and the vessel’s centerline. See section 2.4.1 for this installation setting. Enter the
Bearing Offset as determined in Section 2.4.1.
X & Y Offsets: Determine X and Y offsets for the hydrophone in relation to the pitch / roll center
as explained in section 2.4.2. To enter hydrophone offsets, select HYDROPHONE from the Project
Tree. A dialog box consisting of X, Y, DEPTH and BEARING offsets are displayed. Enter the X and Y
Offsets as determined in Section 2.4.2.
3-53
BATS AND PORTABLE BATS
OPERATION
Hydrophone X and Y offsets are entered with respect to the pitch / roll center of the vessel. It is
assumed that the vertical reference for the pitch / roll center is the water-line of the vessel or the
entered “DEPTH OFFSET”. Once the X and Y Offsets are entered and the dialog box closed, a small
"Hydrophone" symbol appears in the Plotting Window and moves in relation to the X and Y offsets
that are input. This "Hydrophone" symbol represents the actual position of the hydrophone. The
ships reference point remains in the center of the tracking display.
NOTE:
The Trackman software outputs the target position with respect to the pitch / roll
center of the vessel graphically in the Display, numerically in the Status Block and
also on the RS-232 serial communications port.
NOTE:
The X and Y coordinates of the USBL Hydrophone are different from the X and Y MRU
coordinates of the EdgeTech Motion Sensor Unit (Model 4760B). The Z axis polarity
is also different. (The Hydrophone Z Offset is always positive below the water surface
while the MRU Offet below the water surace is negative.) Refer to MRU Manual for
entering offsets into the MRU.
Depth Offset: Manually enter the depth offset as determined in section 2.4.2. This is the Depth of
the hydrophone from the water surface (which is assumed to be on the same plane as the pitch/roll
center of the vessel) to the tip of the hydrophone. Manual mode only. Auto Offset is used only in
special cases.
Attitude Offset: This is the (static) vertical offset of the hydrophone in degrees.
Enter the hydrophone attitude error corrections in degrees. It is used to offset the static attitude of
the hydrophone/staff. The attitude (pitch/roll) offsets are error constants that compensate for the
non-vertical installation of the hydrophone shaft and/or vessel trim. The operator must measure
the angle of the shaft with respect to vertical and enter the data in this menu. Pitch and roll errors
are entered in degrees. Maximum range is +/- 45°.
The attitude (pitch/roll) offset errors follow the polarity convention of; vessel Bow up = [+], Port
up = [+]. For example, if the combined hydrophone shaft and vessel trim causes the Hydrophone
(4610B or 4211A) mounted on the end of the staff) to tilt towards the port side (has the same affect as tilting so that the port side of the vessel is up), the roll error is entered as a positive value.
And, if the Hydrophone is tilted towards the aft of the vessel (vessel attitude = bow down) the
pitch error is entered as a negative value. Also, refer to section 2.4.3.
Pitch and Roll have also been referred to as Tip (fore/aft) and Tilt (port/starboard).
Units: Sets the units that the dimensional offsets are relative to; Meters, feet or Yards.
Orientation: If an EdgeTech remote Pitch and Roll sensor is used, such as the Model 4730A,
4740A or 4760B-V the system can allow for different mounting configurations of these VRU assemblies. In some instances, when attempting to mount the VRU assembly as close to the pitch and
roll center of the vessel as possible, a convenient (bow facing) mounting surface is not always
available. The software can compensate for four different mounting arrangements. The VRU ORIENTATION function allows a VRU assembly to be mounted in the NORMAL position with the assembly's directional arrow facing towards the bow, or mounted to STARBOARD, AFT or PORT.

USBL  Acoustic Data
Brings up Acoustics Data dialog box.
(Same as Acoustic Data in Project Tree)
This data is used within Trackman to
correct positional data based on the
acoustic parameters. Enter the average
water column Speed of Sound in meters/ second or feet/ second or click the
Use Sound Velocity (SV) Profile check
box to enter in the profile or import a
file containing the profile. The default
value is 1500 m/s. The slant range is
calculated using this value and the
acoustic travel time. Enter the Water
Salinity at the hydrophone in part per
thousand. Default is 35 ppt. The TrackPoint hydrophone measures the temperature automatically.
This box should be checked. If not available then a manual temperature at the hydrophone can be
entered in degrees Celsius or Fahrenheit.
NOTE:
When WATER TEMP-AUTO mode is selected the system only updates water temperature
upon receipt of a valid acoustic signal.
NOTE:
The WATER TEMPERATURE and SALINITY parameters do not affect speed of sound calculations. It is used for phase correction (depression angle) at the water / hydrophone
interface.
Sound Velocity Profile
A single velocity profile can be entered by hand or loaded from a file. At each depth there is a
sound velocity value. The data is being assumed to represent the sound velocity layers for the entire region within which you are operating. Therefore, it is assumed that there is no effect on bearing in this model. A non-direct sound wave segment could not be re-directed to the receive point
(from a bearing point-of-view) since the effect is only on z-axis. The only two parameters that require correction are the slant-range (SR) and depression angle (DA).
If the SVP data is available in a printout then manually enter the data within the Sound Velocity
Profile chart below. For example, in layer #1 enter in the Depth and the Velocity associated with
that layer. Continue entering data, filling in the chart down to the depth required. If the data entered for the Velocity is between 1400 and 1700 then it is assumed the data is in meters/second. If
the Velocity values are between 4592 and 5576 then the data is assumed to be in feet/second.
The data entered will be shown in the corresponding Graph. The data entered will be saved as a
csv file under the current Jobs folder. For example, ..\Jobs\TP3\CurrentSvp.csv.

the system will sequence through all the targets, interrogating one at a time.

Internal or External Triggering: If any targets interrogation frequency are the same, the
system will process the replies simultaneously22.

The receive LED flashes at the beginning of the next interrogation cycle. All processing is
performed at the end of the interrogation cycle to determine detection. When targets are
being tracked in sequence it will appear as if the previous reply arrived late when in fact it
was only delayed due to processing.

Receive LED’s will not flash for the telemetry reply.

Internal or External Triggering: A trigger out key is available on each targets interrogation
cycle. This can be used to trigger responder type targets.
22
When tracking simultaneously there is a chance of the beacon replies arriving at the hydrophone
at the same time. In these cases the data will be corrupt and the result is typically a low quality
factor which causes that errant data point to be filtered out. In a dynamic tracking environment
this usually occurs sporadically and does not disturb the tracking of the targets.

BATS AND PORTABLE BATS
OPERATION
To track multiple targets (simultaneously) the BATS sequences through the various reply frequencies while interrogating on one frequency, or it can sequence through the interrogation frequencies and receive the same reply frequency, or a combination of the two. This capability provides the
operator with the versatility to track various combinations of targets. When the BATS sees that the
same interrogation frequency has been selected for a series of targets it automatically processes
the reply frequencies from the beacon within the same interrogation cycle.
Example #1:
Transponder #1 - Interrogation Freq.: 16 kHz, Reply Freq.: M-FSK ORE-01
Transponder #2 - Interrogation Freq.: 16 kHz, Reply Freq.: M-FSK ORE-02
Transponder #3 - Interrogation Freq.: 16 kHz, Reply Freq.: M-FSK ORE-03
Transponder #4 - Interrogation Freq.: 16 kHz, Reply Freq.: M-FSK ORE-04
NOTE:
If the repetition interval is set to 4 seconds, Trackman updates each transponder position every 4 seconds.
Example #2:
Transponder #1 - Interrogation Freq.: 17 kHz, Reply Freq.: M-FSK ORE-01
Transponder #2 - Interrogation Freq.: 18 kHz, Reply Freq.: M-FSK ORE-01
Transponder #3 - Interrogation Freq.: 19 kHz, Reply Freq.: M-FSK ORE-02
Transponder #4 - Interrogation Freq.: 20 kHz, Reply Freq.: M-FSK ORE-02
3.4.1 TRANSPONDER MODE
Acoustic Transponder Mode
To establish tracking in the Transponder mode, the Transponder’s interrogation frequency must
be in the frequency band of the Hydrophone’s interrogation transducer23 and transponder(s) must
be operational and in the water.
From the Beacon dialog box select the SETUP tab and then select Active target. Select the target
symbol that you want the target to be represented by. Enter a name for the target. From the Beacon ACOUSTIC PARAMETER Tab set target type to Transponder, under “Reply Parameters” select
the Reply frequency/Code and the Turn Around Time, under “Interrogation Parameters” enter the
interrogation Interval, the Interrogation Frequency/ Pulse Width or code. (This information is found
the Multibeacon Label, 4370X) Select Trigger source, internal or external. From the DEPTH tab select depth mode or enter in depth manually.
23
The interrogation transducer inside the Model 4610B hydrophone has an optimal frequency range
of 17 to 20 kHz.
3-61
BATS AND PORTABLE BATS
OPERATION
Interrogation Interval for a transponder should not be less than 2 seconds; most transponders
have a 1.5- to 1.75-second lock-out time built in to prevent interrogation echoes from retriggering
the transponder. If interrogating two transponders at different frequencies then it’s possible to decrease the Interrogation Interval to less than two seconds as the Interrogation Interval for a single
target is the total of the intervals. E.g., interrogate #1 at 17kHz every 1.5 seconds and #2 at
19kHz every 1.5 seconds, the sequence interval for the two targets is 3.0s which is still greater
than the lockout time of the transponders. Also keep in mind that when using telemetering transponders the second (telemetry) reply may come in up to one second later than the primary (navigation) reply. Increase Interrogation Interval accordingly.)
NOTE:
With EdgeTech Model 4370 series of transponders, pulse widths of less than 5 msec
may not properly interrogate the transponder.
At a XMIT INTERVAL of 2 seconds, a transponder turnaround time of 15 ms and a speed of sound
input of 1500 meters/second the maximum range the system could track the transponder would be
about 1400 meters. [(1500m/s * (2s - .015s)) / 2 = 1489 m] If a telemetry transponder were used
at its maximum range (telemetry delay of 1 second from primary reply) then the maximum range
would be reduced further to about 700 meters. [(1500m/s * (2s - 1s - .015s)) / 2 = 738.75m]
Input Speed Of Sound
The correct speed of sound in the water column between the transponder and the hydrophone
must be entered for accurate tracking in the transponder mode.
From the Project Tree select
“Acoustic data”. Input the sound speed in meters per second or feet per second or yards per second, depending on the current unit of measure.
The speed of sound in the water column is used to determine the transponder range. The average
water column temperature is usually different than near-surface temperature (the temperature
measured by the hydrophone), and therefore, this speed of sound generally differs from that computed by the operator from a reading of the hydrophone temperature. (The hydrophone temperature is used only to determine the target depression angle correction.)
If the Sound Velocity Profile is known it can either be entered manually or imported from the file.
Check the SV Profile box and click on the “SV Profile Setup” button.
Target Depth
The target depth parameter can either be manually entered, telemetered or input via analog-in
Depth BNC. Choose the method used to update the depth parameter.
The system is now tracking in the transponder mode, and you should observe the following:

Target position displayed in the tracking window, represented by the target designated as the
transponder.

The chosen target symbol shown in the status block with position data agreeing with the target
position on the grid.

OPERATION

Range and bearing information being updated for that target in the status block.

The Target #1 green Interrogate LED flashing for each interrogate signal transmitted, and the
red Receive LED flashing for each signal received 24.

With a transponder at close range the Quality Factors should typically be 9’s or 10’s.
Hardwired Transponder Mode
The Hardwired Transponder mode feature is used where a burst or tone from the transmitter triggers a transponder via an umbilical. A high level transmit burst from a transmitter can be attenuated and impressed on an umbilical to trigger a hardwired transponder. This is useful in situations
where there are not enough conductors available to trigger with the normal responder key out
pulse or there is excess noise causing false triggers. When a target is set up as a Hardwired Transponder, the transmitter is enabled and the slant range is compensated for the one-way acoustic
travel time. Set the Target Interrogation Frequency to the correct value for the hardwired transponder’s receiver. See Note
25
.
3.4.2 RESPONDER MODE
To establish tracking in the responder mode, the proper cable connection must be made at the
Transceiver. Connect the Trigger out signal from the SYNC connector of the Transceiver to the Responder or Responder umbilical cable. To output a differential signal to the Responder connect the
TRIG-OUT1 (pin-M) and /TRIG-OUT1 (pin-L) lines to the Responder. To send a positive going pulse
connect the TRIG-OUT1 (pin-M) and COM (pin-N) signals to the Responder and to send a negative
going pulse connect the /TRIG-OUT1 and COM signals to the Responder. The TRIG-OUT signal levels can either be +5 TTL or +12VDC, as selectable on the internal Peripheral Interface Card (PIC)
within the Transceiver. Default setting is +5V or TTL compatible.
The TRIG-OUT pulse NOT ISOLATED and it occurs on both the transponder (transmit) and responder trigger cycles.
The responder itself must be operational and in the water. Refer to the instruction manual for the
particular responder in use. Follow the steps outlined in the TRANSPONDER section, 3.3.2, to
choose a target, set the frequency, turn tracking on for that target and enter depth. The target
TYPE must be designated as a responder and the Pulse Turn Around Time must be entered.
It is not necessary to set a transmitter frequency for a Pulse Mode responder. The Interrogation
Interval must be set for the maximum range encountered to the responder. E.g., @ 1500 me-
24
The receive LED flashes at the beginning of the next interrogation cycle. All processing is per-
formed at the end of the interrogation as detection is not known until after the next interrogation.

The transponder lock-out time can be reduced in these circumstances to allow for a faster inter-
rogation rate than the normal 2 seconds.
3-63
BATS AND PORTABLE BATS
OPERATION
ters/second velocity of sound and an Interrogation Interval of 2 seconds, the maximum range is
about 3000 meters. The Pulse Width must be set to be compatible with the responder in use. Select Trigger Source, either Internal or External.
3.4.3 FIXED (ARTIFICIAL) TARGET
From the Beacon Parameter dialog box select SETUP Tab and choose a target number/symbol. Under Beacon Status select Fixed Target. In the box below it enter in the target’s bearing and horizontal distance. Select BEARING and enter a value between 0° and 359°, select HORZ RANGE and
enter a value between 1 and 10000 meters.
The total number of targets allowed is four, therefore if two targets are actively being tracked then
up to two Artificial targets can be enabled. A horizontal range and bearing to a target (with respect
to the pitch/roll center of the vessel) is sent to the RS-232 port or entered from the keypad. The
position information obtained for an artificial target could be from a sonar or radar system which
detects a target (underwater or surface) and determines the range and bearing to it. The range
and bearing information has to be corrected for the differences in position between the BATS hydrophone and the sonar/radar transducer (E.g., an offset must be applied so that the data is relative to the vessel’s pitch/roll center). This corrected data is then sent to the Trackman via the RS232 port or manually updated from the keypad/mouse.
If the Transceiver has an external compass input, the artificial target data is corrected for NORTH.
For example, if the vessel heading is 30° and the bearing of the artificial target, relative to the bow
of the vessel is 90°, then the artificial target is compass corrected and plotted at 120°.
NOTE:
The compass heading is only updated if a xponder or pinger is being tracked otherwise the last compass heading received is displayed.
The artificial target data is shown in the Status Block at the bottom of the screen and also sent out
the RS-232 port just as if it were a tracked target.

OPERATION
EXPLANATION OF ERROR CODES
CODE
DESCRIPTION
0
No error. The error code zero (0) does not appear on the screen or sent out the RS-232 interface, but is a null character, indicating no error.
1
Unusable signal received. Signal received, but TrackPoint unable to calculate a position. This
could have been due to acoustic noise contaminating the incoming signal or to other causes.
The red LED and the audio may show valid detection of a signal. No position is plotted.
4460B: Navigation SNR below threshold setting
SUGGESTION: Lower the Signal To Noise threshold in Trackman for that target. (Perform a
noise level test by turning off the beacon and lowering the threshold until the system false
detects. Raise Threshold 5dB above the false detect level.) Put Beacon back in and try again.
If still not detecting then noise could be too high or range is excessive for that beacon or the
beacon’s battery (if applicable) is getting low.
2
Range-gate (or Pinger time-gate) error. (All filter levels) This does not necessarily indicate a
problem, since the signals may be echoes, which should be rejected. Alternatively, the range
gate may have lost its lock on the signal and several more pings may be required for the
range gate to re-acquire the target. No position is plotted.
3
Range cannot be determined. This occurs in transpond or respond mode if the calculated
range is zero. This can happen if a pinger is designated as a responder or transponder and
the transmitter is not turned on. No position is plotted.
4
Low Quality Factor. The signal of the present reply had a quality factor that was lower than
the average of the previous five replies. No position is plotted.
5
Target velocity excessive. Target velocity, based on the change in horizontal position since the
last up-date exceeds 10 knots. This filter takes advantage of the fact that tracked targets
cannot move very fast. This error can occur at filter levels 5 to 10. No position is plotted.
NOTE:
A rapidly turning ship can make the target appear to move fast and can cause this error. To
alleviate this, integrate a compass into TrackPoint.
6
No recent replies. This message appears if, in any mode, no detected signal has occurred for
16 seconds.
SUGGESTION: Check to see if the beacon is in the water. Check Trackman setting VS Beacon label to make sure it is being interrogated with the correct frequency. Check to make sure
the Beacon receive code is correct.

Minimum range error. This occurs when in transponder or responder modes. If the measured
slant range is less than the entered MIN XPONDER RANGE, the message "SLANT RANGE <
ENTERED MIN" is displayed in the status area. No position is plotted.
SUGGESTION: Check the “Limits” parameters under the Beacon Setup dialog/ Filtering Tab.
Make sure slant range to beacon is greater than the minimum range setting.
8
Simultaneous reply interference error. Two replies arrived at same time and cannot be processed. No position is plotted.
10
Travel time less than turn around time (TAT). Either the reply was detected within a time period less than the entered turnaround time or no valid reply was detected and system triggered on noise within the TAT.
SUGGESTION: Check the “Reply Parameters” under the Beacon Setup dialog/ Acoustic Parameters Tab. Make sure the beacon’s Turn Around Time is entered correctly for the beacon
Type in use (Transponder VS Responder). Check Beacon’s TAT. Check Beacon setup parameters.
14
Maximum Slant Range Exceeded: The MAX SLANT RNG filtering function compares the reply’s
slant range against this value. If the slant range is greater than the entered value the status
block shows an error code #14. If the RS232 Format is set to an “EC” format it also outputs
the last good position and tags it with an error code #14. See section 3.7
15
Bearing Limit Exceeded: The BEARING LIMIT function is enabled only in Fish Track mode,
when the angle to the target is fairly well known. The system checks to see whether the target is within the parameters as set by the BEARING LIMITS. This function is only applicable to
targets with a depression angle of less than 45. If a target is outside the set limits then the
system displays an error code #15, "BEARING LIMIT EXCEEDED". These limits are always referenced to the vessel, whether compass mode is ON or OFF.

50
This warning occurs in transponder or responder mode when the target input depth is not
within 10% of the calculated depth, when in calculated depth mode, or within 2% of the calculated depth when in the input depth mode. The warning is triggered when the target depression angle is greater than 40° (from the horizontal). The system calculates the depth at
that point and compares it to the input depth (manual, analog or telemetered); if in error the
warning 50 appears to alert the operator that the input depth may be in error and that a large
excursion of the target position may occur.
51
Pinger Only: This warning applies only when hydrophone offsets are entered and when tracking a pinger where its depression angle is < 20° from the horizontal. Its purpose is to notify
the on-line computer system, via the RS-232, that all ranges and x or y coordinates to that
target are minimum values and generally do not indicate actual ranges. I.e., use this data
cautiously. At small depression angles (less than 20 degrees from the horizontal), measurement of depression and subsequent calculation of horizontal range is highly inaccurate; as a
result, the X and Y hydrophone offsets are ignored for the pinger only, and its bearing is displayed relative to the actual hydrophone location (and North if the compass is enabled). Its
actual range cannot be computed. See Figure 3-31 for an example. This warning applies to
the individual target only.
NOTE:
51 (cont.)
The pinger's bearing data does not degrade in this mode.
When a pinger depression angle is < 20° from the horizontal, the pinger's position cannot be
determined. The TrackPoint shows its bearing accurately with respect to the hydrophone and
places the pinger off-screen along with the trailing dotted line. The transponder position remains with respect to the reference point. The error code 51 warns that the pinger's position
can no longer be calculated, so refer to its bearing value as an indication of position.

52
This warning is set when the target is a pinger and the depression angle is less than 20 degrees from the horizontal. Its purpose is to notify the on-line computer system, via the RS232, that all ranges and x or y coordinates to that target are minimum values and generally
do not indicate actual ranges. I.e., use this data cautiously. The status block and RS-232 data
show the same format as in error code 51. The bearing is referenced to the hydrophone location (and North if compass is enabled). This warning applies to the individual target only.
53
This warning is set when the target is a pinger and the depression angle is between 20° and
45°. In this condition, position accuracy is degraded and the ranges in the status block are
preceded by an approximate "" symbol. This warning applies to the individual target only.

Reserved.
56
When tracking a transponder or responder in calculated depth mode and the target's depression angle is < 45° from the horizontal, this error code warns that the system is no longer
calculating depth in determining target position. The system is using the input depth (manual,
analog or telemetered) and the measured slant range to determine target position. (Also see
warning code 50.) Refer to section 3.4.3 for explanation of depth MODE.
57
This warning occurs when the input depth of the target is greater than the measured slant
range. This can occur when the target depression angle is between 0 and 45° in calculated
depth mode or between 0 and 70° when in input depth mode.
When an Error Code 57 occurs, a -.- is sent out the RS-232 as shown above to indicate invalid
data within the x and y data fields.

This warning occurs if in INPUT mode and either ANALOG or TELEMETRY depth is selected. If
the system calculates a depression angle using the slant range and the input depth to be less
than 45° but the measured depression angle given the phase counts from the hydrophone is
> 70° (sound appears to be coming from below the hydrophone due to high multi-path environment, e.g., directional beacon pointing up in shallow water) then the system ignores the
phase count depression angle and uses the slant range and input depth to calculate horizontal
range.

OPERATION
TROUBLESHOOTING ACOUSTIC PROBLEMS
3.6.1 TRANSPONDER MODE
A transponder emits an acoustic signal of a known frequency in response to an acoustic interrogation pulse sent from the BATS Transceiver. The primary advantage of using a transponder is that
the target range can be measured directly from the round-trip travel time of the acoustic signals.
A transponder, therefore, is NOT subject to the "cone of operation" limitation that applies when a
pinger is used.
A potential (minor) disadvantage in using a transponder (over a responder) is that both the interrogate pulse and the transponder's response may be subject to multi-path.
A high noise and/or multi-path environment may cause any of the following situations:
A.
Transponder cannot "hear" interrogate pulse.
In an extremely noisy environment, it may be impossible for the transponder to distinguish an interrogate pulse in the noise flooding its receivers. In the worst case, the transponder simply won't
reply, and is essentially lost for tracking purposes.
A pinger or responder is a better choice for
such an environment.
B.
Transponder accepts noise or extraneous signals at the correct interrogate fre-
quency.
In this case, transponder replies will be random and uncoordinated with the interrogate pulses.
The operator may observe correct bearing information although range is random and incorrect. To
determine whether this is the case, turn the BATS Transceiver transmitter off and observe whether
the transponder is still replying. If it is, the operator should try to identify and eliminate the source
of the false interrogate signal or noise. If the source cannot be eliminated, it is necessary to
change the interrogate frequency, or switch to pinger or responder operation, or possibly reduce
the sensitivity or frequency of the transponder receiver. It is also possible that there is an interference signal from some other sound source that is the multiple of the Multibeacon frequency causing the detection rather than the Multibeacon triggering on noise. If it is another sound source then
it usually is of a repetitive nature, whereas if the Multibeacon is triggering on noise the detection is
more random.
C.
Reflected interrogate signals cause extra transponder replies.
Most transponders are designed with a 'lock-out' (usually 1.5 - 1.75 seconds), or limit on the rate
at which the transponder can reply, to prevent this from occurring. The operator should be aware
of such a limitation, so that he does not interrogate at a rate too fast for the transponder.
In rare circumstances, the transponder can be replying to a distant reflection of the interrogate
signal in addition to the direct signal. (The reflected signal comes in after the lock-out.) If this is
the case, the operator observes correct bearing values with erratic ranges as above, but the tran-
3-77
BATS AND PORTABLE BATS
OPERATION
sponder will stop replying when the BATS transmitter is turned off, and begin replying when the
transmitter is turned back on, still with erratic ranges.
If this is occurring, the operator should
lower the output power of the transmitter by changing the output jumper on the transmitter board,
or increase the transponder's lock-out time and use a longer interrogate interval.
D.
Transponder replies accurately (in slant range) , but signals are distorted by mul-
ti-path.
When multi-path is affecting transponder replies, try the following:
1.
Lower the hydrophone further from the hull or away from the reflecting object.
Usually multi-path comes from a reflection off the hull or from an object close to the hull and arrives at the hydrophone within one millisecond or two of the direct arrival.
2.
Lower the transponder output power.
If changing the threshold does not eliminate the problem, lowering the transponder output, if possible, may allow the reflected signal to attenuate to a level where it is rejected by the system, but
still receive the direct signal. This is usually only a problem in fresh water where there is less sound
absorption than in sea water.
E.
Transponder responds inaccurately (case B or C) and hydrophone receives reflect-
ed signals.
If the operator observes both erratic range and erratic bearing values, the problem is most likely
some combination of multi-path interference, and the operator should try the following:
1.
Lower the interrogation repetition rate.
In most cases, one signal every three seconds
should give any transmitted or received multi-path bounces time to fade out before the next signal
is initiated.
2.
If a slower repetition rate does not solve the problem (or if the repetition rate is already
slower than two or three seconds), the operator should try to isolate the sources of multi-path and
resolve the independent factors using the above guidelines.
F.
Transponder responds correctly and hydrophone receives correctly giving accurate
slant ranges but erratic bearings.
This is usually a sign of low signal to noise ratio at the hydrophone. The hydrophone receives the
signal and causes a valid detection but the data processing performed on the wideband signal is
not consistent enough for a bearing calculation. In this case the detected signal is usually flagged
with a low quality factor. To improve Signal to Noise ratio at the hydrophone:
1.
Use a “louder” sound source. If the configuration is fixed can a directional beacon with
higher source level be used?
2.
Lower the hydrophone to reduce ship radiated noise.
3-78
BATS AND PORTABLE BATS
3.
OPERATION
Check that hydrophone shaft is not strumming or vibrating excessively. This causes excess
noise at hydrophone. If pole is strumming, change configuration (shorten the shaft, but
watch out for reflections) or add fairing to shaft.
3.6.2 ACOUSTIC PROBLEMS IN RESPONDER MODE
A responder replies acoustically to an electrical interrogation pulse from the transceiver. Like a
transponder, a responder provides the timing information needed to measure horizontal range directly, but the interrogation pulse is not subject to the acoustic interference associated with a transponder. However, because a responder must be electrically connected to the tracking system, it
may not be a feasible option for some operations.
When operating in the responder mode, multi-path interference is limited to cases where the direct
arrival of the acoustic reply is blocked or reflected.
If this occurs, it may be necessary to reconfigure the system so that the hydrophone is in a position to receive the direct signal. For example, the hydrophone may not be mounted far enough below the ship's keel to receive a direct signal from a responder on the other side of the ship.
Avoid an operation where a towfish is tracked behind the vessel near the water surface, so that the
direct signal from the beacon is reflected or attenuated by the ship's wake. Either tow the fish offcenter, out of the ship's wake, or sink the responder below the wake.
When operating in and around subsea structures, there is always a number of locations where
there is no direct path between the responder and the hydrophone, and the operator should expect
occasional multi-path interference in these situations.

OPERATION
RS-232C INTERFACE, BATS TRANSCEIVER
The BATS Transceiver uses the standard EIA RS-232C serial communications interface to communicate with other peripherals such as GPS TimeSync (COM1), heading or pitch/roll sensors. These can be configured from the individual Devices setup dialog boxes. The interface to Trackman is
via the Ethernet port.
COM#1 “USBL to GPS Time”
COM1 is reserved for the GPS/TimeSync interface. To configure the GPS Time interface, from the
Project Tree select GPS/TimeSync from the Main menu go to USBL/GPS Time Sync. Set the BAUD
RATE, the number of DATA BITS required and the number of STOP BITS for the device in use. Connect the COMMs Interface cable (9-pin DEC) between the Transceiver and the GPS device. Data
rate is limited to 16 Hz.
COM#2 or COM#3 “Sensor to USBL”
For a Heading device interface, select from the Project Tree “Heading Sensor” or from the Main
Menu go to SETUP/Compass Sensor. For a motion sensor, select from the Project Tree “Attitude
Sensor” or from the Main Menu go to SETUP/Attitude Sensor Setup. Data rate is limited to 16 Hz.
The NMEA mode allows input of various NMEA compass sentences or motion sensor sentences, with
or without checksum verification, “HDT”, “HDM”, “TCM-2” or “HDG” NMEA formats. Set up COM
port #2 for Compass input under the menu SETUP/COMPASS SETUP/TRACKPOINT (USBL). Select
Serial and then Port Settings. This allows the operator to configure the port’s Baud Rate, Data Bits
and Stop Bits.
ETHERNET Port
The BATS Transceiver’s RJ-45 is wired as a cross-over device so that interfaces directly to a PC. If
the ENET LED is illuminated on the front panel of the Transceiver then the hardware connection is
good. If communications cannot be established then check the PC’s IP address and subnet mask.
PC’s IP usually 192.168.3.X (X = anything but what the Transceiver’s address is. Subnet mask of
255.255.255.0. Port Number 50001. Other IP addresses can be set into the Transceiver, e.g., if
using a local network on a vessel. Contact EdgeTech for details.
3.7.1 HARDWARE
COM#1 “USBL Transceiver”
GPS/TimeSync - The Transceiver’s COM#1 interface is designed to act as a Data Terminal Equipment (DTE) (E.g. Processor Module or PC), If interfacing to a module that has the same protocol, a
null modem is required between the two devices.
COM#2 “USBL Transceiver”
3-80
BATS AND PORTABLE BATS
OPERATION
The COM#2 port is used typically for a compass input. No data is transmitted from this port. The
hardware is setup for bi-directional communications but the Transceiver does not utilize its transmit capabilities. The Transceiver’s COM#2 interface is designed to act as a Data Terminal Equipment (DTE) (E.g. Processor Module or PC), If interfacing to a module that has the same protocol, a

The COM#2 port does not have hardware or software flow control capability. The hardware handshake lines (RTS & DTR) are disabled and do not use the XOFF & XON protocol. If an overrun in
data occurs the data is lost and only the most recent is accepted. (In the case of a gyro or compass
input you would not want the old data but rather accept only the most recent.)
COM#3 “USBL Transceiver”
The COM#3 port is used typically for a motion sensor input. No data is transmitted from this port.
The hardware is setup for bi-directional communications but the Transceiver does not utilize its
transmit capabilities. The Transceiver’s COM#2 interface is designed to act as a Data Terminal

NMEA Formats
General Statement on NMEA Formats: The NMEA data sentences are output in accordance with the
NMEA standard. The electrical protocol can either be RS232 or RS422 depending on the output device of the transmitting unit. Not discussed here. Complete NMEA specification is available in
"NMEA 0183, version 3.0". Standard is published by National Marine Electronics association,
http://www.nmea.org/0183.
The output sentences are a proprietary message which is denoted by the “P” character following
the start of message “$” sign. The “ORE” is the manufacturers three character mnemonic code. The
letter following the ”ORE” is the specific output message identifier for particular format shown.
Data fields in the sentence follow a “,” delimiter and consist of ASCII characters (from 20 – 127
decimal or from HEX 14 to HEX 7E). Because of the presence of variable fields and null fields, specific data fields may only be located within a sentence by observing the field delimiters “,”. Therefore, it is essential for the LISTENER to locate fields by counting delimiters rather than counting
total number of characters received from the start of the sentences.
The Checksum is the 8-bit exclusive OR (no start or stop bits) of all characters in the sentence, including ”,” delimiters between but not including the “$” and the “*” delimiters. The hexadecimal
value of the most significant and least significant 4 bits of the result are converted to two ASCII
characters (0-9, A-F) for transmission. The most significant value is transmitted first. The receiving application should calculate the checksum of the message and compare it to the received
checksum.
3.7.2.1
“PORE” DATA OUTPUT PARAMETER DESCRIPTION
Format “PORE” or NMEA ORE is a NMEA 0183 string length of 70 characters not including
<CR><LF>. It follows the sentence structure for a NMEA 0183 version 2.1 proprietary sentence.
The system automatically switches to this format when the AUTO OFFSET function is initiated. This
allows greater resolution for reading of pitch and roll data. The system reverts back to the previous
format once AUTO OFFSET has been completed.

“$POREB” RS-232 PARAMETER DESCRIPTION
TARGET NUMBER: The TARGET NUMBER (#) represents the various target symbols and can
range from 0 to 10. The zero is output when in the self-test mode to indicate that the RS-232 data
is simulated.
TIME: The TIME value is related to the time of signal reception. It is synchronous with the 24hour time on the screen of the Trackman display. The accuracy of the time as output is within 1
second of the actual time of reply. (In future this will be interfaced to the GPS 1PPS and will be accurate to within approximately 20ms.)
QUALITY FACTOR: The QUALITY FACTOR is a value (1-10) determined by the system on each
reply that is detected. The system uses the phase or time counts from each of the hydrophone elements to determine the quality of the signal. If the phase counts are consistent on all three channels throughout the reply burst the quality factor is very high. If the phase counts have jitter or are
inconsistent then the quality factor is low.
ERROR CODE: The ERROR CODE or WARNING CODE is a one- or two- digit error code indicating that the data received could not be used for a valid position fix, or it can represent a warning to
let an operator know that the position accuracy could be compromised.
TARGET BEARING: The BEARING output in degrees is a relative bearing from the Hydrophone to
the target. The target bearing is corrected for the entered hydrophone offsets, when target is referenced to the pitch roll center of the vessel or if Antenna Offsets are entered, it is corrected again
to the Antenna offset point.
DEPRESSION ANGLE: The DEPRESSION ANGLE is the angle from the horizon to the point directly below the hydrophone. It is in degrees.
3-84
BATS AND PORTABLE BATS
OPERATION
SLANT RANGE: The SLANT RANGE is the measured travel time between the hydrophone and the
transponder. It is only output in meters. The Slant Range is the actual measured slant range to the
transponder or responder. In transponder or responder mode no hydrophone offsets are applied to
the data. If in Pinger mode it is a calculated value with offsets applied if applicable. (See NOTE below.)
SPEED OF SOUND: The SPEED OF SOUND is the entered value from either the keyboard or the
RS232.
TEMPERATURE: The TEMPERATURE is the value as measured at the Hydrophone by the temperature sensor.
TELEMETRY DATA: The TELEMETRY data is independent of the position data. Its value is dependent upon the parameters set under each target's menu. It is an instantaneous value. If telemetered DEPTH is selected for that target instead of telemetered DATA, the TELEMETRY number is
the instantaneous depth value, while Z is the averaged depth value used for positioning calculations.

$POREG RS-232 Parameter Description
TARGET NUMBER: The TARGET NUMBER (#) represents the various target symbols and can
range from 00 to 99. (“00” is the simulated target.) The zero is output when in the self-test mode
to indicate that the RS-232 data is simulated.
TIME: The TIME value is related to the time of signal reception at the Hydrophone. In BATS the
reply detect is accurate to within approximately 35ms. (NOTE: The time at which the sentence is
transmitted from BATS is one interrogation cycle behind the actual detect time. E.g., if Interrogation rate is 3 seconds then the time the data is sent out the RS232 port is about 3 seconds after
the reply detection. But, the time that is attached to the target position sentence is the actual time
that the reply arrived at the hydrophone.)
PHASE A, B, C: The Phase is the time-counts between each element based on the element spacing
and the phase counter clock (50MHz).
TARGET QUALITY FACTOR: The TARGET QUALITY FACTOR is a value (1-10) determined by
the system on each reply that is detected. The system uses the phase or time counts from each of
the hydrophone elements to determine the quality of the target’s signal. If the phase counts are
consistent on all three channels throughout the reply burst the quality factor is very high. If the
phase counts have jitter or are inconsistent then the quality factor is low. (NOTE: In BATS there is
a minimum QF threshold that is set to 3. If the data processed has a QF of 3 or lower the position
will not be plotted. See advanced users guide to over-ride this value in Trackman software. )
ERROR CODE: The ERROR CODE or WARNING CODE is a one- or two- digit error code indicating that the data received could not be used for a valid position fix, or it can represent a warning to
let an operator know that the position accuracy could be compromised. See section 3.5.
TARGET SLANT RANGE: The Target SLANT RANGE is the measured travel time between the hydrophone and the transponder. It is output only in meters. The Slant Range is the actual measured
slant range to the transponder or responder. In transponder or responder mode no hydrophone
offsets are applied to the data. If in Pinger mode it is a calculated value with offsets applied if applicable. (See NOTE below.)

OPERATION
TARGET DEPRESSION ANGLE: The Depression Angle encompasses the angle starting from the
horizontal plane of the hydrophone (0 degrees) and continuing to the point directly below the hydrophone (90 degrees). The TARGET DEPRESSION ANGLE is the angle measured from the hydrophone’s horizontal plane to the target line of sight (Raw DA). (Raw Depression Angle is the default. No Pitch, Roll or Compass corrections applied. Could also be corrected – when Pitch, Roll,
Heading
and
Hydrophone
offsets
are applied. See format
adjusters
below
within the
SENT_OUT.INI file.)
TARGET BEARING: The TARGET BEARING output in degrees is a relative bearing from the Hydrophone to the target (Raw BRG). (Raw Bearing is the default. No Pitch, Roll or Compass corrections applied.) Could also be corrected – when Pitch, Roll, Heading and Hydrophone offsets are applied. See format adjusters below within the SENT_OUT.INI file.)
X, Y, Z: Horizontal position and depth of Target output in Meters. Corrected for Compass (if “DATA O/P” is selected in Trackman program)
and also Pitch / Roll. It is also offset to the vessel’s center of gravity
when Hydrophone X, Y & Z offsets are entered. The “Z” or depth value is referenced to the water surface.
HEADING: The Compass / Gyro value (degrees) as input either via NMEA sentence (from BATS or
Trackman PC) or via the ANALOG input in BATS.
PITCH: The PITCH value (degrees) as input either via an NMEA (BATS or Trackman) or via the
ANALOG (BATS) input. 0 degrees is horizontal, a positive pitch is bow up.
ROLL: The ROLL value (degrees) as input either via an NMEA (BATS or Trackman) or via the ANALOG (BATS/TP3) input. 0 degrees is horizontal, a positive roll is port side up.
TEMPERATURE: The TEMPERATURE is the value as measured at the Hydrophone by the temperature sensor. In degrees Celsius. (Not used for Speed of Sound measurements.)
OPTIONAL…
SIGNAL to NOISE RATIO:
This figure is the Signal To Noise ratio of the received signal in dB.
Signal is compared against the noise around the detected signal. (I.e., signal is compared against
an instantaneous noise figure rather than averaged.) If value is less than the Target’s threshold
value then target will be output with an Error Code 01. (Target default threshold is 20dB but can be
raised or lowered from the Trackman users menu.)

OPERATION
3.7.2.12 RS-232 PARAMETER DESCRIPTION
These are the descriptions of the parameters used in the Format Sentences above unless otherwise
listed.
The TARGET NUMBER (#) represents the various target symbols and can range from 0 to 9. The
zero is output when in the self-test mode to indicate that the RS-232 data is simulated.
The TIME (TOD) is output at the beginning of each target's data. It is synchronous with the 24hour time on the screen of the Trackman PC. It is equal to the time that the Trackman PC received
the acoustic reply. When synchronized with the GPS clock the accuracy of the time as output is
within 50 milliseconds of the actual time of reply.
The HEADING (HDG) is only displayed when a compass interface is used. The HEADING can either
be the Magnetic heading of the vessel or the True heading, if the NMEA heading data has been determined to be corrected for True North. The NMEA ORE output sentence shows an identifier in the
string to show whether data is Magnetic (M), True (T) or from an Analog source (A). The heading is
also displayed on the Status Display of the Trackman PC’s screen.
The BEARING (BRG) output in degrees is a relative bearing from the ship to the target. When the
compass interface is in use, and the SYSTEM / COMPASS / RS232 TGT DATA is set to North Ref.,
the target bearing is referenced to North. The target bearing is corrected for the entered hydrophone offsets (target is referenced to the pitch roll center of the vessel) or if Antenna Offsets are
entered it is corrected again to the Antenna offset point. The SYSTEM / COMPASS / RS232 TGT
DATA switch can be set to either NORTH REF or BOW REF. See section 3.4.2.
The DEPRESSION ANGLE output on REV4 formats is the depression angle calculated from the final horizontal distance and the depth (either input or calculated depth). The depression angle output on the NUWC formats is the angle as measured by the hydrophone’s three elements but it has
been corrected for pitch and roll motion. It is not compensated by the hydrophone X,Y,Z deviation,
caused by the offset between hydrophone and vessel pitch / roll center. (I.e., the arc that the hydrophone swings through during vessel motion.) System takes wherever the hydrophone was when
the reply was received and reconverts depression angle based on a gravity level measurement at
that position.
The SLANT RANGE (S.R.) is the measured travel time between the hydrophone and the transponder. It is output in meters, feet or yards, depending on RS-232 UNITS selection. The Slant
Range is the actual measured slant range to the transponder or responder. In transponder or responder mode no hydrophone offsets are applied to the data. If in Pinger mode it is a calculated
value with offsets applied if applicable. (See NOTE below.)
The X and Y position are the coordinates from the ship to the target. They are output in meters,
feet or yards if STANDARD, STANDARD-EC, STD W/PR, STD-EC W/PR, NCSC or NMEA ORE is selected, or just meters if Format REV 4 or REV 4-EC is selected. If NMEA TTM is selected then the X
and Y ranges are in kilometers.
3-105
BATS AND PORTABLE BATS
NOTE:
OPERATION
Smoothing occurs on the target position only (X, Y or Horizontal Distance, Brg), NOT
the slant range. For non-pinger targets the slant range is displayed in the status
block and sent out the RS-232 as the actual value. For pinger targets the slant range
is calculated and smoothed.
The Z (depth) can be either a manually entered value, a telemetered value, an analog input value
or a calculated value. Z is in meters, feet or yards if Format STANDARD or STANDARD-EC STD
W/PR, STD-EC W/PR, NCSC or NMEA ORE, NUWC or NUWC-EC is selected, or just meters if Format
REV 4 or REV 4-EC is selected. If NMEA TTM is selected then Z range is in kilometers.
NOTE:
Filter settings 6-10 cause the analog or telemetry depth (Z) to average the last three
readings. Filter settings 1-5 do not average the input depth.
The TELEMETRY (TELEM) data is independent of the position data. Its value is dependent upon
the parameters set under each target's menu. It is an instantaneous value. If telemetered DEPTH is
selected for that target instead of telemetered DATA, the TELEM number is the instantaneous depth
value, while Z is the averaged depth value used for positioning calculations.
The ERROR CODE (ERR) or WARNING CODE (WARN) is a one- or two- digit error code indicating
that the data received could not be used for a valid position fix, or it can represent a warning to let
an operator know that the position accuracy could be compromised (see ERROR and WARNING
CODES, section 3.15).
PITCH and ROLL is either from the PITCH and ROLL from the hydrophone VRU (Models 4610B Hydrophone or 4740A VRU/Amplifier) or a remote VRU (Dynamic motion monitoring sensor, such as
the EdgeTech Model 4414A). The units are in degrees. When the SYSTEM / OFFSETS / HYDROPHONE / VRU / STATUS function is set to ACTIVE a positive PITCH is output the RS232 when the
BOW of the vessel is UP and a positive ROLL is when the vessel rolls to starboard or PORT side UP.
If the internal VRU STATUS function is set to STATIC, configured for remote VRU sensing, the
NMEA ORE format changes to follow the incoming voltage polarity instead of the BOW UP/PORT UP
protocol.
The QUALITY FACTOR is a value (1-10) determined by the system on each reply that is detected.
The system uses the phase or time counts from each of the hydrophone elements to determine the
quality of the signal. If the phase counts are consistent on all three channels through-out the reply
burst the quality factor is very high. If the phase counts have jitter or are inconsistent then the
quality factor is low.

3.7.2.13
OPERATION
TRACKMAN REMOTE INTERFACE
The Trackman Program can accept commands from a remote PC along with sending target data out
on the same port. From the DEVICE LIST select Remote Interface from the list. Set the connection
Type, the IP settings or COM port settings, and the Sentence Settings. The command “Sentence In
to Trackman” format can either be TP-SPC (EdgeTech Proprietary) or NCSC. The “Sentence Out
from Trackman” can be any of the ones from the DATA OUTPUT as shown above. (Future option.)
3.7.2.14
NCSC COMMAND STRUCTURE
The NCSC RS-232 control method uses predefined packets of information to control operational parameters. These packets are used to perform SYSTEM and TARGET setup modifications.
NOTE:
The only setup that is not duplicated exactly to the NCSS specification is in the FILTER LEVEL setting. The new filtering method precludes using the same five codes to
control the new filter level. A translation table takes the five codes and changes the
new filter level to a setting that is close to its original. See Target Setup Command 3
below.
The following commands are in the process of being updated to fit in with the BATS parameters.
Do not use at this time.

The numbers in parenthesis ( ) are the extended characters if the year is sent to the Trackman in 4
digits vs 2.
For data sent to Trackman, the “SY3” command has been modified to allow 4-digit entry of the
year. The existing 2-digit year value remains valid also. If the system receives 4-digits within the
year field (before the trailing space character is received) it accepts the value with the following
rules applying. If the year is less than or equal to 1950 it assumes it is 20XX. If it is greater than
1950 then it assumes it is 19XX. If it receives only two digits that are less than or equal to 50 it
assumes it is 20XX. If it is greater than 50 then it assumes it is 19XX.

PRINCIPLES OF OPERATION
PRINCIPLES OF OPERATION
BATS (Broadband Acoustic Tracking System) measures and analyzes sound waves sent from an
acoustic sound source that is attached to a target. The signal is received by a hydrophone to determine target position relative to the tracking ship. The hydrophone amplifies the received acoustic signals and sends them to the Transceiver and then to the PC for further processing by the
Trackman Software.
The BATS uses an ultra-short baseline, phased-array hydrophone containing sound transducing elements arranged at the vertices of an equilateral triangle. Each element is spaced less than half a
wavelength away from each of the other elements in the array. When a sound wave impinges upon the array it strikes one element first, then one of its neighbors, and finally the remaining element.
The sound wave, as sensed by any element in the array, appears out of phase with the
wave as sensed by the other elements in the array. The phase differences between the elements
in the array provide the information required to calculate a three-dimensional vector from the array
to the sound source.
Three types of sound sources are used with the BATS: pingers, transponders and responders. A
pinger emits a sound pulse at a predetermined frequency, repeated at a set interval. The hydrophone receives the pulse and determines bearing and depression angle. Transit time of the pulse
is unknown.
A transponder emits a sound pulse in response to a specific acoustic interrogation pulse from the
controller transmitter. A responder emits a sound pulse via a wire connecting the responder and
the Signal Interface Module (SIM) when electrically triggered by the SIM.
The system now has
timing information to calculate directly the slant range of the target, assuming the average velocity
of sound in the water column and the turnaround time of the transponder or responder are known.
In either pinger or transponder/responder mode, the relative bearing and depression angle of the
target being tracked are determined by measuring the phase differences of the sound waves for
each hydrophone element. The bearing of the target is measured in degrees relative to the hydrophone heading. The depression angle is formed by the intersection of a horizontal plane and a line
drawn from the vessel reference point to the target. Once these values are determined, the rest of
the positioning parameters can be calculated.
NOTE:
The term "vessel reference point" denotes the point relative to which all measurements are calculated. The actual position of the vessel reference point is determined
by hydrophone offsets entered into the system (see Figure 4-1). If no offsets are entered, the hydrophone itself is considered the vessel reference point. This is the case
in Figure 4-2, which illustrates the positioning parameters that the system calculates.
The slant range is the straight line distance from the vessel reference point to the target. When a
sound source other than a pinger is used, the travel time of the sound wave between the sound
4-1

PRINCIPLES OF OPERATION
source and the hydrophone is used to calculate the slant range directly. The horizontal range is
the projection of the slant range on a horizontal plane.
In PINGER mode, horizontal range (HR) is calculated by:
Z
HR =
tan 
where Z is the target depth and  is the depression angle.
Slant range (SR) is calculated by:
Z
SR =
sin 
where Z is the target depth and  the depression angle.
In TRANSPONDER or RESPONDER mode, slant range (SR) is calculated from the known speed of
sound in the water column (V), the transponder or responder turnaround time (D) and the measured time (T) between transmitted pulse and received reply by:
SR = V x
(T - D)
2
SR = V x
(T - D)
in transponder mode, and:
in responder mode.
Horizontal range (HR) is calculated by one of three methods, depending on the calculated value of
the depression angle () from the horizontal and the depth MODE.
A.
In CALCULATED depth MODE and when the target is within a 90 degree cone (value of ()
greater than 45 degrees), horizontal range (HR) is calculated by:
HR = SR cos 
This is the normal situation, where the target is within a 45 degree angle from the vertical axis of
the hydrophone.
B.
In CALCULATED depth MODE and outside a 90 degree cone (values of () less than 45 degrees), as the target moves to positions which are between the hydrophone horizon and a
45 degree depression angle, the measured accuracy degrades due to physical constraints of
the measuring hydrophone. (As the target approaches the horizon, the angle becomes unmeasurable.) In this situation, the input target depth (Z) (manual, analog or telemetry) is
used to calculate horizontal range by:
Z
4-2
BATS AND PORTABLE BATS
PRINCIPLES OF OPERATION
HR = SR cos (sin-1
)
SR
C.
In INPUT depth MODE and when the target is within a 40 degree cone (value of () greater
than 70 degrees), slight variations between the slant range and the input depth causes
large horizontal position differences. In this situation the horizontal range is calculated by:
Z
HR =
tan 
D.
In INPUT depth MODE and when the target is outside the 40-degree cone (value of () less
than 70 degrees), the horizontal range is calculated by:
Z
HR = SR cos (sin-1
)
SR
To eliminate the sharp boundary at 45- and 70-degree depression angles, hysteresis is incorporated into the software.
In Figure 4-2, the values X, Y, and Z are RS-232C outputs. (These values are distinct from the X,
Y and Z offsets shown in Figure 4-1.) The distance X is the projection of the horizontal range on a
vertical plane perpendicular to the centerline of the vessel and passing through the vessel reference point. The distance Y is the projection of the horizontal range on a vertical plane parallel to
the centerline of the ship and passing through the target. X and Y and HR form a right triangle.
Depth (Z) is the depth of the target below the water surface.
Under ideal conditions the transducing element plane is parallel to the surface of the water and
perpendicular to a vertical plane through the vessel centerline. In a real application, the vessel and
hydrophone are in motion, and the system must therefore correct measurements taken from the
hydrophone for pitch and roll.
The rotation of the vessel about its X-axis, a line drawn perpendicular to the vessel centerline at its
midpoint, is known as pitch. Roll is the rotation of the vessel about the vessel centerline, or Y-axis.
The Vertical Reference Unit measures pitch and roll in degrees, with zero degrees being the "at
rest" position, and calculates the necessary compensation. For dynamic motion compensation an
EdgeTech Model 4760B MRU (Motion Reference Unit) is recommended. This would typically be interfaced to the Trackman PC.
The Embedded PC, located in the Transceiver, receive information from the hydrophone array for
each received pulse. They convert that information into a real-time graphic representation of the

HYDROPHONE
Model 4213C-B Hydrophone Assembly
The hydrophone assembly consists of the hydrophone and the pressure case/electronics. In the
hydrophone, the three receiving elements and the transmitting element are potted and attached to
the PVC base, and connected to the electronics. In the pressure case/electronics package, each of
the three elements feeds its own Amplifier on the Amplifier Board. A precision temperature sensor,
located on the Amplifier Board, provides an analog signal which is sent to the Transceiver. The medium frequency unit is calibrated from 17 to 30kHz and the Low is calibrated from 8 to 16kHz.
Model 4211A-B Hydrophone
For existing Model 4630 Gate Valve installations, the Model 4211A Hydrophone can also be used to
interface to the BATS. The mounting/mechanical dimensions are the same as the 4211B but the
connector has been change to the 4213C-B type.

CALIBRATION FILES
MAINTENANCE
The hydrophone assembly is calibrated at the factory. The Trackman Software uses the Hydrophone calibration files to correct for the offsets within the Hydrophone. The calibration files consist
of two binary files; XXXXYYYY.bhi & XXXXYYYY.blo. These files contain offsets which compensate
for the variances from hydrophone to hydrophone. When ordered as a system, these files are installed in the PC at the factory. If a hydrophone assembly is ordered separately, it comes with a
floppy or CD with a set of files on it, and must be installed into the PC to which Trackman Software
is installed.
The CAL file’s first 4 characters are the Transceivers “Input & A/D” PCB S/N’s (if applicable) and
the last 4 are the Hydrophone S/N’s. The extensions of the two files are .blo and .bhi. (Binary Low
byte 1-8 and Binary Hi byte 9-16.) For example…
00001038.bhi
00001038.blo
If the Transceiver S/N’s are 0000 then the Hydrophone can be used with any BATS Transceiver.
(There are no phase errors within the A/D Card.)
The CAL Files reside on the Trackman PC (Laptop) or Model 4451A under;
c:\Program Files\ORE Offshore\Trackpoint MMI\CalFiles\InUseCAL\*.bhi
c:\Program Files\ORE Offshore\Trackpoint MMI\CalFiles\InUseCAL\*.blo
If a new Hydrophone is used with the system, the set of Calibration files from the new Hydrophone
must be copied into this directory. Only one set of *.bhi & *.blo files can reside under this directory. Move the older CAL files under a new directory called…
c:\Program Files\ORE Offshore\Trackpoint MMI\CalFiles\OldCALFiles\
The original CAL files are also located on the CD that came with the system in case the Trackman
Software is installed on a new PC.

CARE OF CABLES
GENERAL NOTES:
Refer to caution below for disassembly of underwater cable connections.
CAUTION
Whenever underwater connectors are disassembled, or pressure cases opened, water is drawn into
the cavity formed by the separating parts. This water, particularly salt water, enters as a fine spray
and coats the electrical contacts and other parts inside. It is extremely important to minimize this
buildup of moisture and salt, as it causes corrosion and voltage breakdown, particularly on power
leads, which have high voltages present. Therefore a thorough cleaning is required, preferably immediately after opening the parts. It is also helpful to rinse in fresh water and remove excess water from parts prior to opening.
NOTES FOR PROPER CARE OF UNDERWATER CABLES:
DO
Lubricate connectors before mating.
DO
Keep cables free from dirt and salt.
DO
Secure cables with tie wraps or tape so they won't work free.
DO
Route cables where they won't get pinched or crushed by deployment or moving machinery.
DO
Periodically clean cable contacts with a cleaner/degreaser.
Lubricate with
clean lubricant after cleaning.
DO
Check cables with a VOM & megger periodically for electrical integrity.
DON'T
Walk on cables.
DON'T
Bend cables near the connectors.
DON'T
Use damaged cables with bad or questionable contacts.
They will damage
their mating half.
DON'T
Hang things on cables.
DON'T
Use cables for towing or pulling.
DON'T
Bend the connectors when mating or disconnecting.
DON'T
Clean cables with light hydrocarbon solvents (i.e. acetone, lacquer thinner,
paint thinner).

STATIC DISCHARGE
BATS AND PORTABLE BATS
APPENDIX-B
APPENDIX B
ELECTROSTATIC DISCHARGE (ESD)
The printed circuit boards within the TrackPoint 3 console can be damaged by ESD. Many of the
electronic components are sensitive to electrostatic discharge. Some devices can be damaged by a
potential as low as 30Volts. People are a prime source of device-damaging electrostatic potentials.
Activities such as walking or working at a bench can generate thousands of Volts of static potential.
This charge is transmitted to a person’s conductive perspiration layer, and when a charged person
handles a static sensitive device, the component may be damaged by either direct or indirect discharge of the static potential to the device.
NOTE: A person typically will not feel static discharge until the potential approaches 3500 Volts.
An electronic device exposed to static discharge may not be affected at all and will work perfectly
throughout a normal life cycle. It may, however, function normally for a while, but because of degradation in the internal layers of the device, its life expectancy may be reduced. The ESD event initiates a device weakness that degrades and causes failure with continued use.
RULE 1: Assume all electronic (solid state) components are sensitive to ESD damage.
RULE 2: Never touch a sensitive component or assembly unless properly grounded. When handling
circuit assemblies or when working with them, always use the appropriate grounding procedure:
wrist strap connected to ground or heelstrap with a grounded dissipative floormat.
RULE 3: Never transport, store, or handle sensitive components or assemblies except in a staticsafe environment. Use static shielding bags when transporting circuit boards.
If a grounded dissipative floor-mat or wrist-strap is not available then at the very least, when
swapping out Printed Circuit Boards, discharge yourself to the chassis of the unit. Lift out circuit
board from chassis and immediately put it on a conductive surface. Remove the new circuit board
from its anti-static bag only after grasping the anti-static bag (with PCB inside) and the chassis.
Remove board and place directly inside chassis. Put replaced board in the spare’s anti-static bag
for transport/storage.
