Operator Manual
Purpose of this Manual
This operator manual describes how to operate the WMB-80F MultiBeam Sonar System program through its graphical user interface.
Introducing the WMB-80F Multi-Beam Sonar System
The WMB-80F is a Multi-Beam Sonar system that uses wide-angle sonar
transducer to profile the water column and seafloor to very high resolution. It is this unique combination of Multi-Beam sonar and computer
processing power which provides you with unparalleled information
about the fishing environment. It gives you a wide 120° port-starboard
swath of the water column and seafloor, allowing you to find and position reefs and wrecks, fish schools, seafloor hardness changes, and
foreign objects in the water column or on the seafloor. From the 120°
swath, the system processes 112 dynamic beams, with each beam containing detections from the water column and seafloor.
The information is presented in a user-friendly, mouse controlled, Windows-based operating system. The system can output data to plotting
software packages. For optimal performance, roll, heave, pitch, heading
and position inputs are all required.
Mapping an area of the seafloor requires motion compensation to compensate for the motion of the vessel. The efficiency
of motion compensation strongly depends on the quality of the
motion data. Accurate ship measurements must be taken and
the dockside and sea trial commissioning procedures carried out
thoroughly during installation. Even with good sensors, mapping
performance in rough seas will be less accurate than in calm
water.
The WMB-80F can be applied to a variety of fishing methods, as well as
search and rescue, customs, and police applications.
Main Features
The WMB-80F has the following main features:
►
►
Improved performance.
The use of separate transmit and receive arrays has enabled WASSP to optimise both transmit performance and receive sensitivity, giving improved performance over traditional sonar and sounders.
High detail picture of marine environment.
The transmit beam spreads over a 120° port-starboard swath and covers 4° foreaft while the receive beam covers 10° fore-aft, displaying a highly detailed picture
of the marine environment.

Beam stabilisation.
Beam stabilisation compensates for the movement of the vessel, providing accurate seafloor profiles and fish school locations.
Variable beam width.
Unique to the WMB-80F, the single beam view can not only be stabilised, but
the beam width can be varied from 5° to 40°.
Triple beam view.
With variable width and angle, the port, centre, and starboard beams display
together to help build your understanding of the sea environment.
Bottom lock.
Bottom lock provides a traditional bottom lock mode where the changes in bottom depth are ignored and the bottom is drawn flat. Fish and other echoes are
shown relative to the flat bottom image, enabling better discrimination between
bottom fish and the seafloor.
Computer based profile storage.
A computer-based system means the WMB-80F can generate and store very
detailed seafloor profiles.
Digital signal processing (DSP).
Using DSP technology, the WMB-80F can provide an indication of changes
in seafloor hardness, ideal for scalloping, crayfishing, and trawling where you
want to understand and locate small changes on the seafloor.
80 kHz operating frequency.
Operating at a frequency of 80 kHz provides high seafloor definition with good
depth coverage.
2-D and 3-D zoom.
2-D zooming from 250 m out to 3 km. 3-D zooming from 10 m out to 1 km.
Depth and seafloor coverage.
Seafloor coverage is determined by the beamwidth in use: For a 90 degree
beamwidth, the seafloor coverage will be approximately twice the water depth.
For example, 100 m depth gives 200 m seafloor coverage with 112 beams every ping. For a 120 degree beamwidth, the seafloor coverage is 3.4 x depth.
For example, 200m depth gives approximately 680m seafloor coverage.
Unique power management system (16 power levels).
16 power levels provide optimal performance over a wide range of seafloor
types and water depths.
More accurate 3-D.
Profiles 90 times faster than conventional single beam echo sounders, leading
to reduced costs and improved accuracy.
Future proof technology.
The computer based operating system and transceiver firmware are both upgradeable as new software features are developed.

Viewing Modes
Sonar View The sonar view shows the water column and seafloor profile below the
transducer. This represents a sonar view of the water column and seafloor as seen from behind the vessel. See Figure 11.
TIPS
If there is a secondary sonar
or sounder operating on the
vessel, you may see pulses of
interference from this device
on the sonar, triple beam, and
sidescan displays. To reduce
this interference select the interference filter in the Advanced
Options box. See Advanced
Options for details.
A 120° wide by 4° long swath or footprint is covered. The system generates 112 beams over the 120° footprint to provide a very high-resolution sonar view. The centre 90° of the swath or footprint is used to develop seafloor profiles and gives a seafloor coverage of twice the depth
(e.g. 100 m depth gives 200 m seafloor coverage).

Seafloor Tracking – is the method used by the program to constantly display the seafloor during scanning operations regardless of the
changes in seafloor depth. This is indicated by the word (Tracking)
being tagged to the end of the words Manual Zoom in the Text Box.
Seafloor Tracking must be selected in the sub-menu and the Range
Control Knob set to automatic (GREEN). If Seafloor Tracking is deselected in the sub-menu, the word (Tracking) disappears from the
Text Box. If the Range Control setting is in manual mode (YELLOW)
and the seafloor then drops below the range setting, the seafloor will
stop being tracked (and lost from the screen).

The Fish Threshold control allows you to tune the “Fish Detection”
for your vessel. The control has a range of 0 to 20. Initially set to
zero, a higher number will ignore small echo signals and thus prevent noise showing up as fish targets. Reducing the Fish Threshold
number will increase the sensitivity but will result in echo returns due
to noise showing up as fish targets. Try varying the Fish Threshold
setting up and down until you get one which is optimum for your vessel’s installation.
Backscatter Overlay Options
Selecting Show Backscatter in the right-click options applies backscatter to the contour view of the seafloor along the profiled area. The
colour scale is BLACK to WHITE with:
• BLACK = NO return (weak echoes).
• WHITE = HIGH return (strong echoes).
The lighter the colour on the screen, the stronger the return.
Using this display you can determine areas of hard / rocky ground (light
areas) and areas of soft, sandy, or kelp covered ground (dark areas).
Right-clicking in the sidescan view opens the right-click options box.

Setting the Gain Threshold Limits:
The Gain Threshold Limits set a reference value for the maximum level of
backscatter that will be scaled into white colours. The limit is typically between 60 and 65, and is set at time of commissioning the system. Once set
the limit rarely needs adjustment.
To set the limit, sail over an area of seafloor that is known to ave a high
backscatter return (for example rocks). Set the Backscatter Brightness adjustment slider to minimum (bottom). Adjust the Backscatter Gain Threshold value up or down until the map is very dark except for small white areas
where the highest backscatter is received. The Backscatter Brightness can
then be adjusted to give the desired picture. The brightness control can be
varied at any time without affecting the saved backscatter maps, but changes to the Threshold Limit will alter the reference point for all backscatter
values saved after the change.
N.B. - The Gain Threshold Limit can only be changed by a technician and
requires a Technician Dongle.
Warning - changing these at a later date will cause earlier recorded seafloor
backscatter data to be displayed incorrectly.
Advantages
 Shows the vessel location and heading relative to the seafloor features, fish marks, and
backscatter information.
 When showing fish overlay, colours for depth (seafloor) revert to greyscale.
 Mark options.
 History is saved and the data can be seen when visiting an area days or years after
collection.
 Backscatter overlay shows changes in seafloor type clearly. Good for navigating a trawl
path for fish only found in specific areas.
Disadvantages
 In shallow depths <45 metres, resolution of the contour view is less than the sonar view.
 The contour view picture relies on software algorithms to trace the seafloor correctly.
Wrecks may trace as fish and vice versa.

Note: WASSP systems with earlier versions of software
had the height set to a fixed ratio of 2:1.

In shallow depths <40 metres, resolution of the contour view is less than the sonar view.
The contour view picture relies on software algorithms to trace the seafloor correctly.
Wrecks may trace as fish and vice versa.
Sidescan View The sidescan view is a sidescan picture generated from the sonar data
received by the system. The display is drawn on the screen as a waterfall
– the newest information appears at the top of the screen, while the oldest falls off the bottom of the screen. This is similar to the way sounder
displays operate, except that in their case the new data appears on the
right and the old data disappears off the left of the screen.
The left side of the sidescan view shows the signals received from the
port side while the right shows signals received from the starboard
side. By default, the sidescan view starts at the centre of the vessel and
works its way out to port and starboard.
As the sidescan image moves further out along the seafloor, the picture
shows features on the seafloor. Objects, such as rocks, appear as bright
white marks followed by a shadow. Harder ground gives strong returns
(lighter on the grey scale), while a patch of mud or kelp causes a dark
patch/shadow to appear. See Figure 18.
The primary advantage of the sidescan view over the other views is in
locating and identifying objects on the seafloor off to each side of the

vessel. Some structures such as a shipwreck may appear like a large
fish school on the sonar view and thus not appear as an object on the
contour or 3-D views.
In Figure 20, the sidescan view allows you to interpret the sonar information from a different view point, showing a wreck just above the
seafloor as a clearly shaped structure.
Due to the nature of the origin of the data, any signals of significant
strength register as a faint mirror on the opposite side of the display.
Standard sidescan systems generally rely on a towed transducer that is
held deeper in the water, having the advantage of a lower aspect ratio.

Interference Filter
The Interference Filter enables a reduction
in interference caused by other ultrasonic
sub-sea acoustic devices such as sounders. It also provides some noise filtering.
It is recommended that the interference
filter be left selected (ON) if you have
another sounder or sonar on your vessel that operates at the same time as the
WMB-80F. Best results will be obtained is
all other sounders are switched off.
Set the Interference Filter Level to High
when encountering strong interference,
and Low when interference is weak.
Smoothing
Smoothing only affects the single beam
view. It allows averaging of the individual
seafloor samples in the longitudinal (foreaft) direction to eliminate the quantised or
pixelated effect that would otherwise be
visible on the single beam view. Generally,
the best value for smoothing is 2.

Minimisation describes the filtering process used to remove sidelobe signals.
Sidelobe generated signals show up as a ring on the sonar view where the
transmission pulse first strikes the seafloor, or as a mirror of features on either
port or starboard.
Sidelobe generated features can confuse the sonar picture making it hard to
interpret. However, too much minimisation can also distort the sonar image.
Refer to the Installation Manual IM_WMB80F_SYS, for more information on selecting correct minimisation settings for your installation.

Transducer Depth. Provides the ability to compensate for the depth the transducer is mounted below the water line.
Pitch / Roll Sensor Offsets. If using an external sensor connected to the transceiver, these settings allow you to enter the specific zero angle voltage and sensitivity voltage characteristics of the roll sensor you are using. If a motion sensor is
not installed, it is recommended that you disable roll compensation.
Heading Offset. Provides a heading offset dial so that compensation for errors
in the ships heading can be corrected. The most common reason for a heading
offset is when magnetic heading information is being given instead of true heading. If true heading is being given, the heading offset is usually 0. Otherwise a
heading offset should be entered as appropriate. Heading offset can also be used
to compensate for transducer misalignment, causing a heading error.
If the vessel is travelling in a straight line in the direction it is facing, you can
adjust the heading offset quite accurately by eye. Look at the vessel track on
the contour display and the bearing line and adjust the heading offset until
they are parallel (the bearing line should point away from the track made on the
contour display behind the vessel). If the vessel’s heading changes erratically,
make sure that there are not multiple conflicting heading sentences being fed
into the WMB-80F’s serial ports.
Note, roll sensor settings
shown are the default values.

Salinity
The default value for the salinity of sea water is 35. This value should
not be changed unless the actual salinity of the surrounding water is
known. If fishing in fresh water, the value should be set to 1. Clicking on the Calculate button will re-calculate the Surface Sound
Speed value based on the Salinity and Surface Temperature values.
Absorption Loss
As sound travels through water, some of the energy contained is absorbed by the water, resulting in attenuation of the signal. The chosen
value of absorption loss is used when calculating and displaying backscatter information. For an 80kHz WASSP system, a default value of
25dB/Km is used. This is set at time of installation and affects the appearance of the backscatter display. This value should not be changed.

Operator Manual
Sensor Values Tab
The Sensor Values tab provides a roll corrections slider to compensate
for any offset between the WMB-80F transducer mounting and the water
line. If the transducer and motion sensor are not mounted on the same
angle this will also require compensation.
Figure 32 – Ship Setup Options Box – Sensor Values Tab
Inaccuracies with roll correction make it harder for the system to compensate for any changes in roll. If roll correction is enabled (on the
Sensor Values tab) and the vessel is rolling less than 25°, the sonar
picture should remain in almost the same place from ping to ping. If the
sonar picture moves with the vessel then the roll compensation setting
is likely to be wrong. The Swap Roll selection check box allows toggling
to reverse the polarity of the roll sensor. If correct, the display does not
move. If not correct, the display could roll 2x what the vessel is actually
rolling.
If the roll sensor and or the transducer are not mounted entirely flush
you may have to move the Roll Correction slider to compensate. The
Roll Correction has been automated and is set at time of installation
when the Sea Trial Commissioning Patch Test (Roll Correction) is performed. Provided the Use Patch Roll box is checked, the WASSP application software will use the calculated value.

Swap Array
Do not engage the
Extra Roll Filter in

The Swap Array check box is used to account for wiring differences between different versions of the WMB-80F. If you find that the shallow part
of the harbour, or a significant landmark, is appearing on the wrong side
of the Contour / 3-D display, then there is a chance you have this option selected when it should not be, or vice versa. Engage the Extra Roll
Filter when the vessel is rolling greater than 5º and the roll compensation
is not fully compensating for the roll motion.
Pitch Offset
A Pitch Offset box allows you to set a pitch offset setting in degrees to
correct for transducer and motion sensor mis-alignment. See Figure 32.
GPS Time Delay
All GPS positioning systems have some delay from receipt of the satellite
signal to outputting the correction data. When a Furuno SC-30 is used as the
source of position data, this delay is 1.2 seconds. and equates to an error of
about 10m in the location of an object on the seafloor. This value should only
be changed if the type of position sensor is changed.
For more detail on how to set the values on the Sensor Values Tab, refer to
the WASSP Installation Manual, Commissioning Proceedures, Sea Trials.
Motion Delay
The motion delay value is displayed for information only and cannot be
changed. The value is determined by selecting the type of motion sensor in
the Ship Setup Options General Tab - See Figure 29.

swath, choose high. Where bottom detail is important, e.g. rocks or wreck
outline, choose a lower setting. Lower settings may result in a more uneven
appearance of the ocean floor between adjacent mapping swaths. The chosen
setting is a compromise between bottom detail and uniformity of the ocean
bottom map. The Default value sets smoothing to Medium.

Power Tab
The Power tab displays 16 power levels, seven in the low range and
nine in the high range. Each power level can be individually set from
the sixteen drop down boxes. A Defaults button sets all sixteen power
levels to a default setting. When setting power level depth settings individually, click the Apply button when you have completed the settings.
If a power level is set out of sequence, for example level 5 is set to 50
m, level 6 is 105 m and level 7 is 90 m, then a WASSP information box
appears and informs you that a specific power level is invalid (level 6 in
our example). Level 6 can then be set individually to a depth below that
of level 7 and above level 5. See Figure 34 below.
The “Use Power Correction”
check box should normally
be ticked. This corrects for
changes in power levels in
SideScan and Backscatter
modes.
Click OK and reset Power
Level 6 to a depth between Power Levels 5 and
7. If no other power levels
have been changed, clicking “Defaults” will reset
the power level.

Operator Manual
Question 1 The WMB-80F System is transmitting too slowly, how can I
speed it up?
Remember that the WMB-80F system must acquire twice the depth of
standard sounders to enable the full seafloor profile across 120°. If the
entire profile is to be captured, the ping rate will need to be at least half
that of a standard single beam sounder.
Manually adjusting the range down will increase the ping rate significantly but will result in the loss of seafloor information, including break
up of the 3-D display after a point. If you are only interested in the centre beam of the triple beam display, the range control can be reduced to
just over half the current depth in metres. At all other times, the range
control should be set to automatic mode (green). The optimal range is
twice the current depth in metres.
Other programs running at the same time as the WMB-80F program
consume processing power and take processing time away from the
WMB-80F system, slowing down the rate of transmission. For optimal
performance, ensure the WMB-80F program is the only application running.
Question 2 Why does the range not change on the display when I move the
Range Dial?
Double-click each viewing mode (sonar, single / triple beam, 3-D, contour, and sidescan) to reset the view so that automatic range control
is re-enabled. The range continues to track the range dial while in this
mode. If any zooming is done with the wheel mouse then automatic
range control will be disabled again until you once again double-click on
the appropriate view.
Question 3 Why is no sea floor profile generated on the 3-D or contour
views after the system initially starts transmitting?
Check that the NMEA data input is being received and that the communications ports are configured correctly. If the range for data collection is too small, the system cannot acquire the seafloor and cannot
track the range automatically. Enter the manual range mode and set

the range deep enough to acquire the seafloor before returning to the
automatic range mode. Also check that the Contour Map button is ON.
See Page 11.
Question 4 Why do gaps appear between the swath footprints on the contour and 3-D views?
There are multiple possibilities here:
►
►
►
►
►
►
►
The vessel may be travelling too fast to map the seafloor in this depth of water.
The range setting could be set much larger than necessary and as a result the
system is transmitting slower than is optimal.
The computer is giving processing power to another operation (other than the
WMB-80F program) causing processing of sounding information to take longer
as a result lowering the transmission rate of the WMB-80F system.
The GPS data has come in at irregular intervals.
The WMB-80F system has stopped. See Question 5.
The GPS data source may have dropped out completely preventing the system
from mapping the seafloor data to its appropriate location. Ensure an isolation
device is being used to convert the current loop NMEA to RS-232.
The seafloor detection may have briefly failed due to aeration or excess noise
Question 5 The WMB-80F system has stopped transmitting without operator
intervention?
If time is taken from the system by another application for long enough,
the WMB-80F system may restart transmission in a number of seconds.
If the system does not restart, try stopping and then starting the system using the MODE button on the toolbar. If this does not work, try to
restart the WMB-80F program and the transceiver. The most likely cause
of this is a sudden power supply spike or drop.

the front panel flashes every few seconds.
• Make sure the CAT5 network cable is connected at both the
Transceiver and
the PC ends (unplug and re-plug to make sure).
• Check that the Transfer Task application is running (look for the icon
on the Start Bar at the bottom of your PC screen) and was running
when you started WASSP. If not, restart WASSP after running the
Transfer Task application.

Question 8
What does the error message that appears when I run WASSP mean?
Is my WASSP system faulty?
Consult the list below for the cause/course of action if an error message is displayed in WASSP.
• Cannot Find Tide TCD File:
Use the tide function to search for a valid database file.
Check file is present in directory- if not present, reinstall.
• Error Loading TVG File:
Check in the Windows Control Panel under Regional and Language Options,
Regional Options, Customize, Numbers Tab, that the “Decimal Symbol” setting
is set to a ‘ . ’ rather than a ‘ , ’ (comma)
Check file is present in directory- reinstall if unable to locate.
• “Too Many Files With This Name. Aborted.”
This occurs when storing raw data using the data recorder if there are more
than 1000 files of the same initial name in a directory. Change the name or
directory if you wish to continue to save raw data files. NOTE unless you
require the raw data for some purpose it is not recommended to record raw
data files – these files are very large (≈ 2Gb/hour) and will require careful
management in order to prevent the Hard disk drive of your computer from
becoming full. A computer with a full disk drive becomes unusable. Try to
have at least 10 Gb of free drive space at all times to allow sufficient room for
system file management.
• Cannot set power levels. Power Level x invalid:
This occurs when setting the power level settings when the depth values do not
increase as the power levels increase. Check that every depth selection for
each sequential power level is greater than the previous.
• No Dongle Found In System. Please Plug Dongle In And Try Again.
This error can occur if the USB device has not been detected by windows or
the Dongle is not connected to the system. Remove the dongle if it is already
in place and then reconnect it to the computer after a few seconds. Press the
retry button. The system will operate in replay mode without a WASSPDONGLE
but will not work in real time.
• No License File Found On Dongle.
The most likely cause of this error is that the WASSP dongle has been modified
or the contents have become corrupted.
If the license file has been removed from the dongle the system will not
operate.
Contact your dealer to source a new WASSPDONGLE – you will need to return
your current faulty Dongle.
• License File Is Corrupted.
The licence file on the WASSPDONGLE has been modified in some way and is
no longer valid. Contact your dealer to source a new WASSPDONGLE – you will
need to return your current faulty Dongle.

No Attitude: No Pitch:
The system is configured to compensate for Pitch and there has been a gap of
multiple pings where there was no Pitch data received. Check the Motion
Sensor configuration in WASSP. Also check the Serial Port configuration in the
WASSP Transfer Task and finally that the sensor itself is on and operating
correctly.
• No Attitude: No Heave:
The system is configured to compensate for Heave and there has been a gap of
multiple pings where there was no Heave data received. Check the Motion
Sensor configuration in WASSP. Also check the Serial Port configuration in the
WASSP Transfer Task and finally that the sensor itself is on and operating

multiple pings where there was no Roll data received. Check the Motion Sensor
configuration in WASSP. Also check the Serial Port configuration in the WASSP
Transfer Task and finally that the sensor itself is on and operating correctly.
• LINK ERROR:
This error message indicates that there has been a data corruption internally in
the Transceiver between the Receiver and the DSP. The WASSP system will not
function at this point. Reset the power to the Transceiver – if the message
continues to be shown return the system to your dealer for service.
• TX PWR ERROR: This warning informs the operator that the Transmitter did
not reach full voltage during the system start up sequence - the most common
cause for this is a low 24V power supply voltage/current. If the system
appears to operate correctly after you see this message then this is not an
issue. If the system does not appear to function then the error implies that the
Transceiver Transmitter unit has failed - Contact your Dealer for further
assistance.
• CARRIER REF ERROR: This error message indicates that there has been a
failure in the synchronised internal timing chain of the Transceiver. If restarting
the power to the Transceiver does not clear this error return the Transceiver to
your dealer for service.
• SERIAL FAILURE: This error message indicates that an internal DSP board
communications failure has occurred. The WASSP system will not function
correctly at this point. Turn the power off/on at the Transceiver – if the
message continues to be shown return the system to your dealer for service.
• System Initialisation Failure: This error implies that the system was not
fully operational when the WASSP GUI was run. Shut down the shuttle P.C.
and the Transceiver and do a complete re-start. If the error message continues
to be shown, refer to the troubleshooting section on Page 41, or contact your
your dealer for further assistance.

Question 9
Why is there a ring displayed just above the seafloor? What causes
these ‘ring’ marks? How can I get rid of them?
This ring is a by-product of the multi-beam technology of your WASSP system.
It is supposed to be there but in practice we want to make it as difficult to see
as possible. To avoid these rings confusing the sea floor tracking algorithms or
being confused as fish marks the Minimisation feature allows these rings to be
suppressed on the Sonar display.
The ring is caused by mathematical limits – when a very strong signal arrives at
the receiver it creates a shadow like effect that creates a ring of much weaker
echoes. Unfortunately the signal return from the sea floor is many orders of
magnitude stronger than a fish echo and thus the shadow of weaker echoes are
comparable to fish targets.
How do I know if I have a problem then? – From experience in the field a
minimisation level around 3000 is normal. Some systems may have as low as
1500 others up to 5000, often as a result of newer or older technology. If the
minimisation required to remove traces of these rings is much higher then there
could be a problem. If you have a minimisation level of lower than 6000 and
can’t see any rings then your WASSP system is probably operating correctly.
If you have the system working with no sign of these rings and then they start to
appear and you have not changed the Minimisation settings then something has
changed for the worse – keep reading.
There are a number of ways to optimise the performance of your WASSP system
and to reduce these rings:
a) Too much power – This is the most common cause of problems. When there
is too much acoustic energy in signals returned from the sea floor they may
distort. Distortion of the signals will cause ambiguity in resolving the position and
thus create rings of very high amplitude.
b) Shading of Receiver – Any difference across the receiver caused by marine
growth or any other irregularity across the face of the receiver will contribute to
a reduction in the discrimination of the WASSP system. This will lead to higher
intensity rings.

Version:
V1.3
Issue Date: 15 Dec 2009
Operator Manual
87
c) Reconnection Fault – If the cable from the Transceiver to the Transducer was
disconnected and has been reconnected recently it is possible the receiver is
connected incorrectly. Check the colour codes of Ethernet connections are in the
correct order.
d) Calibration – It is possible that the system calibration was disrupted by another
sounder, close the WASSP GUI and re-run to allow the system to recalibrate.
e) Electronics Failure – If one or more channels fail in the electronics this will
increase the intensity of the ring.
f) Configuration – Changes made in the Technician configuration could significantly change the system performance. Check Windowing, Power and Pre-processing
options. If possible reverse any changes made if the system configuration deteriorates. If the changes are unknown make a note of all ship setup information,
backup the WASSPPRO.INI file and then delete the original to run the WASSP
system with default configuration settings.
Question 10
What is this constant signal on the sonar/fish finder display?
There are many sources of noise, interference and general acoustic reflections
which can make these bathymetric displays difficult to use. A description of the
different types of noise and ways in which you might be able to determine and
eliminate them follows.
Sonar/Sounder – Other Sound producing devices will produce constant blips on
the WASSP sonar display which will vary in intensity and size depending on the
transmission power and angle of the system. If you wish to continue using your
other sounders you can suppress this noise using the Interference Filter option.
Aeration – Air in the water around the transducer can cause transmitted signals
to be absorbed or reflected prematurely resulting in false signal reports from the
transducer.
Biomass – Large bodies of photo plankton can float through the sea covering very
large areas. This may be the source of large areas of constant faint signal return
through a region of the water column.
Own Transmission – WASSP shows all received signals starting from half way
through the transmission pulse. Thus you should see a red or yellow ring at the
top of the Sonar display. As power level and pulse width increase this signal
return will be stronger and larger.
Keel Reflection – If the WASSP system is mounted in such a way that transmitted
signals can reflect off the ships hull you may find that there is a constant strong
return shown on the sonar display. This may happen even if the hull is just outside the 120degree transmission swath. If a strong signal follows the boat and
is within the dimensions of the ship then this signal is probably a reflection off
your own ship. This will make it hard to detect fish at this depth but otherwise
shouldn’t affect the performance of your WASSP system.

Electrical – There are an almost infinite number of ways in which Electrical Noise
can influence system performance. The first priority is that the system be well
grounded – this means a large and preferably short grounding wire connects the
Transceiver to the Power supply ground. WASSP is relatively protected by noise
on Power supply sources but a very noisy supply could cause trouble. More likely
causes of electrical interference are if noisy, high power machinery or wiring is
run beside the transducer cable. Electrical noise is either constant, regular or
transmit power dependant.
Water Temperature Layers – A thin faint horizontal line that is present ping after
ping in the same place could be a temperature layer. The Sea is often layered
with various temperature layers due to pressure and surface mixing. Often a
reflection can be created at the depth where a significant change in water temperature occurs – causing an acoustic return.
Prop Noise – If the turbulent water flow off the props is directed onto the transducer face this could create aeration noise. Especially relevant for lower frequency models – it may be possible to pick up the prop noise as an acoustic source.
For this reason it pays to mount the transducer some distance from the ships
props. Prop acoustic noise will appear on the side of the Sonar display close to
the prop and will look like a regular pulse or solid signal depending on the rotation speed.
Vibration – Shudders of vibration and vibrating mounting structures can induce
significant noise. Additionally a vibration in mounting can cause motion compensation of the system to fail. Sharp jolts and vibrations will generate rings of high
signal.
Question 11
Why is my WASSP System not tracking the Seafloor?
Any source of Noise mentioned in the answer to Question 9 above can cause
the seafloor detectection to fail if it is bad enough. In some cases bad noise can
cause the tracking to fail and it could take a number of pings for the WASSP system to reacquire the seafloor. In some instances noted below and in bad cases of
noise it may not be possible to automatically resume seafloor tracking.
Power – If too much power is being used for the depth of water you are operating in, the seafloor tracking signal could be noisy especially if there is enough
power to cause signal distortion as the tracking algorithm may track the rings
produced by this. Conversley, too low a power level may result in the signal levels from the sea floor being below the noise floor of the system and thus they will
be ignored as noise. This will tend to cause the surface noise to be considered as
a bottom detection candidate.
Depth – The WASSP system can acquire a sea floor profile swath 3.7 times the
nadir depth but this requires the acquisition depth to be at least twice that of the
maximum depth on that swath. WASSP takes this into account and when the
Depth Dial reads 100m the system acquires to 210m. If the acquisition depth is
in manual mode or the system fails to track down with the seafloor then you may
need to manually increase the system range to allow it to reacquire the seafloor.

Fish – Occasionally a very large dense school of fish can be detected as a mountain on the seafloor. This should be easy to determine with a second pass over
the area at a later time. This function also allows wrecks to show on the contour
display as these are often similar in density to fish schools.
GPS Position – If there is no position the WASSP system will not output depth
data and will cease to write contour maps.
Minimisation – The seafloor tracking is affected by the Minimisation level; ensure
this is set appropriately as described in the Installation Manual on Page 50.
Question 12
Why doesn’t the seafloor line up when I go over it again?
There are several factors which can cause this to show on your WASSP display,
however remember that if the vessel is operating in a high sea state, your motion
sensor may not be able to fully compensate for the vessel’s movement:
GPS Time Lag – The standard Furuno SC-50 and SC-30 Heading sensors have
a 1.2 second delay on GPS data. Ensure that any GPS delay is entered into the
Ship Setup Configuration as this will cause large errors in depth.
Motion Compensation – To make good use of motion compensation we must
ensure that the WASSP transducer and any Motion sensors are securely mounted
and do not move at all. The dynamic and static accuracy of the motion sensor
effectively determines the differences you can expect when you pass over the
same area again.
Sea State – Motion Compensation is a complex process and makes some assumptions – the bigger the sea state and the smaller the boat the less reliable the
seafloor data will be as there is more reliance on the accuracy of measurements
and the input from the motion sensors.
Cornering – Motion compensation is costly to do to the nth degree. Most low end
Motion sensors have poor performance on corners due to the centripetal acceleration forces caused by a turn affecting the delicate balance of the sensor. Thus
sea floor detections collected while the boat is turning are likely to be of lesser
quality than those collected in a straight line.
Water Temperature – The water temperature and salinity affect the sound speed
and thus the angle at which the sound moves through the water column. This
causes the sea floor to curve up or down as noted in the operator manual. If
the seafloor exhibits a curve up or down on the edges, adjust the sound speed.
Note: The surface water temperature will probably change during the course of a
day.
Tide Correction – Tide is essential for matching up overlapping swaths. If you
have disabled the Tide correction the swaths will rarely line up on your WASSP
displays. Ensure that the ZDA sentence is being collected and sent to the WASSP
computer so it can determine the UTC time and use the correct tide correction
value.

Transducer Offsets – The transducer, GPS and draft offsets need to be input into
the WASSP ship setup configuration so that the motion induced errors in the seafloor can be correctly compensated for.
Roll Offset – If there is a fixed offset in the mounting of the transducer or Motion
Sensor you will need to conduct a patch test to determine this error. Without this
the roll correction will not work correctly.
Question 13
Why does the Seafloor Move if the system is Motion Compensated?
The Contour and 3D display are fully motion compensated. The other displays
are only compensated for Roll to save on processing time and to avoid creating
artefacts in the data. If the Sonar display is rotating then the Roll correction is
not working. Remember too that if the vessel is operating in a high sea state,
your motion sensor may not be able to fully compensate for the vessel’s movement.
Check Roll Information is being received (Open the Raw Information Form and
check the Roll Graph displays roll waveforms). You should see a red line on this
display if the Roll information is being processed.

• Check that the device that you receive roll information from is on and that all
your serial cables are still connected to your WASSP Computer.
• Check that the correct sensors are selected in the Ship Setup Form, this
configuration could have been inadvertently changed.
• Check that the Roll Configuration settings have not been changed. If the
transducer array has been re-installed, the Swap Array setting could have
changed in which case you will need to invert the Roll Configuration. When in

doubt, use the values that were recorded in the Installation Manual at time of
commissioning. If the roll offset is incorrect a slight roll of the display will occur.
If the roll polarity is incorrect you will see a doubling of the actual vessel roll
(i.e. complared with having the roll compensation disabled).
• Use the WASSP Network Status screen to check that you have not disabled the
Serial port. Check that the serial port with the Attitude data is being used.
These must be
on for data to be
used by WASSP
Check Sum on is
recommended.
Finally if the sea floor is not uniformly flat you could see rapid changes in the
sonar display with each ping as the ship moves across the sea floor. As there is no
heave or pitch compensation on this display it will often move up and down and
if the sea floor changes angle it will also appear to roll a bit. If you are unsure
check that the seafloor remains flat on a flat piece of seafloor and remember that a
vertical shift is expected if there is vessel roll, pitch and or heave. These artefacts
should be mostly removed when you look at the WASSP Contour display which is
corrected for the measured attitude elements

Question 14
The mode button animates as if pinging but nothing happens. What is
wrong?
If you are looking at the Contour or 3D displays these will not update without
GPS information, sea floor profile information and mapping is enabled. Check
your GPS is on. This can be validated by checking the network input screen or
transfer task diagnostic displays. If the seafloor line is not being traced on the
Sonar display or the Mapping has been disabled then new data will not be added
to the Contour Maps.
Increase the gain, and range. Can you see noise on the Sonar Display? If not
reset the power to the Transceiver, and reset the PC and retry. If this problem
persists and there are no error messages, contact your dealer. If you are getting an error message or messages, look at the relevant information for the error
message in that section of the FAQ.
Ensure that the Transducer has not been disconnected from the Transceiver, both
the receiver cables and the transmit cables need to be connected in order for the
WASSP system to operate. If problems persist after a full system shutdown and
power up then contact your dealer.
