RS-422 A and B signal definition

According to the following standard the signal state definitions are:

• IEC 61162-1. The idle, marking, logical 1, OFF or stop bit states are defined by a negative voltage on line A with respect to line B. The active, spacing, logical 0, ON or start bit states are defined by a positive voltage on line A with respect to line B.

It should be noted that the above A with respect to B levels are inverted from the voltage input/output requirements of standard UARTs and that many line drivers and receivers provide a logic inversion.

Figure 3 Principle drawing for talker and listener circuits

The RS–422 serial ports on the Processing Unit have galvanic isolation on both talker

(transmit -TX) and listener (receive -RX). Interface circuits are fed by a DC/DC converter with galvanic isolation (transformer) and signal isolation is provided by optocouplers type HPCL 06. Transmitter/receiver data circuits are of type LTC491. The transmit part may feed up to 32 listeners if the minimum DC load is above 60 Ohm. The receiver -RX termination in the Processing Unit (100 R) is switched on off by FW/SW.

Note

With reference to the table showing the pin layout for the serial ports on the rear panel screw terminals, note that the separate “GND” pin for each port is isolated from the chassis and shall act as a common signal intended to be connected between the talker

(-TX) and the listener side (RX) of other equipment, for example the corresponding isolated “GND” pin or common pin. The purpose of the common signal is to increase the reliability of the hardware transmission. It must not be connected to the chassis or the cable screen. This applies to both sides of a connection. The cable screen shall be connected to the equipment chassis on one side only, preferably talker side, -TX.

G210-14/3.0

• LAN 1 in the front . This is primarily a service port and has less capacity (10/100

Mbps) than the other LANs. To connect this LAN to a network, a straight-through twisted pair (TP) cable with RJ-45 connectors must be used. A straight-through cable is one where the pins of one connector are connected to the same pins of the other connector. In special instances a crossover cable instead of a straight-through cable is needed, for example when connecting a Processing Unit to another Processing Unit.

Below is the pin wiring for the different TP cables:

4 Installation

This chapter covers installation of the Processing Unit and the GNSS and IALA beacon antennas. A separate Installation manual covers Seastar demodulator installation and connection to the Inmarsat terminal on board the vessel for reception of DGNSS correction signals.

Note

The Processing Unit has a plastic film on top to protect from transport scratches. This film must be removed before operation as the plastic film will reduce the heat transfer from the unit and thus cause temperature increase inside the unit.

The installation includes:

• Location of the system parts (the Processing Unit, GNSS antenna and IALA beacon antenna)

• Installation of the coax connectors

• Installation of the GNSS antenna(s) and cable(s)

• Installation of the IALA beacon antenna and cable

• Connection of cables between DPS system and external equipment

• System configuration

4.2 Location of system parts

The following sections contain instructions regarding location of the various system parts.

4.2.1

GNSS antenna

The most critical aspect of the system installation is the location of the GNSS antenna.

Incorrect or inadequate installation can lead to poor positioning performance or complete loss of position.

If the antenna is installed in a poor location, it can suffer from masking, multipath or interference from other radio sources which can affect the position performance.

Masking

The GNSS antenna should have an unobstructed line of sight to the sky. The signals from the satellite propagate by line-of-sight, which means that if the antenna cannot see the satellite, the reception will be severely impaired, if it occurs at all.

Potential obstructions are other masts and antennas, cranes, rigs and fixed platforms, buildings in ports, high cliffs or hills close to shore. The impact of this can be anything from degraded performance to a complete loss of positioning.

Figure 7 Good antenna location

G210-14/3.0

Figure 8 Bad antenna location

Multipath

Inappropriate location of the antenna can result in the antenna receiving reflections of the incoming signal as well as the signal itself (multipath). The reflected multipath signal takes a longer path than the direct signal, introducing an error into the position calculation.

Figure 9 Multipath

G210-14/3.0

Kongsberg DPS 232

Interference from other radiating sources

Interference can be caused by close proximity to other radiating sources. Installing

GNSS antennas in close proximity to satellite communication systems operating in or nearby GPS/GLONASS frequency bands (1.2 to 1.6 GHz) should be avoided (i.e. Sat C,

Iridium). Ideally the antenna should be situated at a minimum of 3 metres from other radiating sources. As this is not always practically possible, a compromise location must be sought.

Recommended distance to Sat C is 2 to 3 metres horizontally and 0.5 to 1 metre vertically.

Figure 10 Recommended distance to Sat C

During installation, comprehensive tests should be carried out for potential interference by conducting transmissions from each RF source for extended periods, individually and simultaneously.

4.2.2

IALA beacon antenna

The IALA beacon antenna should be protected from direct illumination of radar beams and other transmitting antennas such as Inmarsat antennas.

• Do not mount the antenna near transmitting antennas, radar arrays or satellite communication equipment.

• Do not mount the antenna near areas that experience high vibrations, excessive heat and electrical interference.

4.2.3

Processing Unit

When installing the Processing Unit, note the following:

• The Processing Unit can be mounted on the bridge or in the instrument room.

• The unit is designed for indoor installation and should not be exposed to heavy vibrations, transformers or similar.

• The unit should be resiliently mounted in a 19-inch rack to be in accordance with the environmental standard IEC60945/EN60945.

G210-14/3.0

• The unit has an internal fan and requires free airflow from the rear and out to the sides.

It is recommended that ventilation or air conditioning is provided in order to keep the ambient operating temperature around +20 °C. The best location is typically in the instrument room or on the bridge mounted into a 19-inch rack with good ventilation and resilient mounting.

• It is recommended that the area around the unit is kept free from dust and static electricity.

• All connections to the unit are on the rear side and available space for cable connections and service must be provided.

4.3 Cabinet installation

4.3.1

Installation with delivered cabinet

The cabinet should be securely mounted. Drilling plan for the resilient mountings is included in the attached drawings.

Caution

The cabinet must be connected to a grounded outlet.

It is recommended that the cables attached to the rear of the unit should be long enough to accommodate all service from the front.

The cabinet must be mounted in such a way that the minimum cable bends (on the rear side) are not exceeded.

For the antenna cables it may be necessary to use the short transition RG-214 cable in order to route the cables properly into the cabinet.

4.3.2

Installation without delivered cabinet

A system delivered without a cabinet shall be mounted on attachment rails in a standard

19-inch rack. Minimum depth of the rack is 600 mm.

Caution

The rack must be resiliently mounted, otherwise the warranty will be void.

The rack should have air inlet on top and bottom or ventilation splits on the sides. The

Processing Unit has ventilation on the sides. Forced ventilation may be required if the cabinet contains several electronic modules.

Screened cables are connected to the back of the unit, directly on the rear panel or on a connector block with screen terminals. All cables connected to the unit must be screened.

Make sure that the minimum antenna cable bends are not exceeded.

4.5 Antenna and cable installation

As the signals involved are inherently week RF signals, great care and attention should be taken regarding the selection and installation of the RF cabling and connections made.

Attenuation of GNSS signals should be considered when selecting cable type, as signal loss will dictate maximum lengths. The number of connectors and other components, such as lightning protection devices, which will attenuate the signal, should also be taken into account.

The maximum length of the antenna coaxial cables is 80 metres for the cable types normally supplied with the system. If longer cables are needed, an RF Fiber Optical

Link should be used.

G210-14/3.0

GNSS antenna installation on page 91 for more details.

Note

The specified cable length of 80 metres only applies to the GPS–702–GG-N antenna delivered with the system. Other lengths may apply to other types of antennas.

The RF Fibre Optical Link is used as an antenna cable extension allowing the distance between the antenna and receiver to be extended to several hundred metres.

It should also be noted that a too powerful signal may cause saturation of receiving circuitry in shorter cable runs, making it necessary to use signal attenuators or cables with higher attenuation levels.

Sharp bends, kinks and unnecessary connections should be avoided.

External connections should be appropriately treated with self-amalgamating tape other preparations to keep out water.

As far as is practically possible, antenna cables should be kept separate from other cables which may cause electrical interference, for example power cables, radio transmitter cables, Inmarsat and VSAT cables.

When installing antennas and cables ensure that:

• Cable runs are not close to any hot work area or touching any hot surface.

• Cables are not bent too much.

• Correct types of cables are used.

• Cables are secured and labeled.

• All connectors are securely fastened.

• All antenna connections are sealed.

4.5.1

GNSS antenna and cable installation

The cables used for the GNSS antenna are RG-214 and ½" Cellflex superflex.

Caution

If the antenna cable is attached to the Processing Unit, do not attach the antenna cable to the antenna when the unit is running. If the antenna cable is short-circuited with POWER ON, the GNSS receiver will be damaged.

How to install the antenna

1 Attach the antenna to the mounting rod and attach the rod to the ship's masthead or pole with proper mounting hardware like U-bolts or hose-clamps.

2 Attach the antenna interconnection cable to the antenna and connect the ½" Cellflex superflex cable to the other end of the interconnection cable.

3 Wrap outdoor cable connections with waterproof self-vulcanising tape. An alternative way of waterproofing is to use heat shrink hose with glue. The hose should cover the whole connector and part of the cable.

G210-14/3.0

Kongsberg DPS 232

4 Dependent on the cable installation, secure the cable to the mast every one to three metres with clamps or bands (non metal).

Note

The cable running from the GNSS antenna to the Processing Unit should be as straight as possible. Do not crush or crimp the cable with tie-downs, as this will affect the electrical properties of the cable.

5 Check the antenna cable for short-circuiting. Route the connector at the other end of the antenna cable to the main unit.

6 Connect the cable to the Processing Unit. A short interconnection cable is delivered in order to get secure cable runs into the cabinet.

4.5.2

IALA beacon antenna and cable installation

The construction of the mount enables routing of the cable either along the inside or the outside of the mast tube. An RG-214 cable is used for distances shorter than 50 metres, while an ½" superflex cable is used for distances longer than 50 metres.

Caution

How to install the IALA beacon antenna

1 Attach the antenna to a mast tube or pole by using the provided U-bolts.

2 Attach the antenna cable to the antenna.

3 Wrap outdoor cable connections with waterproof self-vulcanising tape. An alternate way of waterproofing is to use heat shrink hose with glue. The hose should cover the whole connector and part of the cable.

4 Make sure the ground strap at the antenna base is connected to a suitable place ensuring good grounding. When installed, the terminals of the ground strap should be sealed from moisture to prevent corrosion. Paint or silicone sealant is recommended for this.

5 Secure the cable to the mast every one to three metres with clamps or bands.

6 Route the connector at the other end of the antenna cable to the main unit. Connect the cable to the Processing Unit. A short RG-214 cable is often needed in order to secure cable runs into the cabinet. This cable is included in the package.

4.6 Electrical installation

The electrical installation consists of:

• Connecting a cable between the GNSS antenna and the Processing Unit.

• Connecting a cable between the IALA antenna and the Processing Unit.

• Connecting cables with output data between the Processing Unit and external equipment.

• Connecting cables with DGNSS corrections to the Processing Unit (optional).

• Connecting monitor, keyboard and mouse.

• Supplying power to the Processing Unit.

Caution

Attach the antenna cable to the GNSS antenna on the mounting rod before attaching the antenna cables to the Processing Unit. If the antenna cable is attached to the Processing Unit, do not attach the antenna cables to the

GNSS antenna with the Processing Unit powered on. If the antenna cable is short-circuited with power on, the GNSS receivers within the Processing

Unit will be damaged.

5.4 Vessel configuration

Vessel configuration consists of three views: Geometry, Description and Equipment.

5.4.1

Vessel geometry

In the Vessel Geometry view, information needed to specify correct location of various sensors, equipment and monitoring points on a vessel is entered. The drawing is correctly scaled based on the vessel dimensions to ensure correct indication of the various points.

The unit of the entered coordinates is either [m] or [ft].

G210-14/3.0

Figure 15 Vessel geometry view — default vessel shape

Vessel shape from file on page 52.

Select the check boxes Show sensors , Show equipment or Show monitoring points to display objects defined in other views.

Shape type

The Shape type section defines the shape of the vessel hosting the system. The list contains some general shape outlines: Ship, Rig, Jackup (3 leg) and Jackup (4 leg).

These are all scaled according to the dimensions given in the Shape dimension section.

The general shape outline can be overridden by an actual shape defined in a drawing file

(extension .svi

— Seatex Vessel Image). This file can be create or edited in a text editor.

Select the Use vessel drawing check box, and browse for the wanted drawing file by clicking the Browse button. When a valid drawing file has been loaded, the dimensions are defined by the loaded shape and the Shape dimension fields are locked.

Shape dimensions

In the Shape dimensions section it is possible to set the following parameters:

Overall length

The overall length of the vessel, i.e. from stern to bow.

Overall width

The overall width of the vessel [m].

Overall height

The distance from the highest point of the vessel to the keel.

G210-14/3.0

Kongsberg DPS 232

Origin location in drawing

All point locations in the configuration refer to the origin. The location of the origin is defined using distance from stern, center line and keel (often referred to as the CRP — coordinate reference point — in survey reports).

From stern

The distance from the aft point of the ship to origin along the X axis.

From CL

The distance from the vessel’s centre line, positive towards starboard.

From keel

The distance from the keel, positive downwards.

5.4.2

Vessel shape from file

The pre-defined scalable vessel shapes represent the actual vessel outline only in rare cases. In order to configure the accurate location of various sensors, equipment and monitoring points, it is recommended to load a separate vessel model from file.

Select the Use vessel drawing check box, then click the Browse...

button to browse for an image file. Three file types are available: Vessel models(*.svm) , Vessel vector images

(*.svi) and Old vessel images (*.txt) .

G210-14/3.0

The system supports two types of two dimensional outlines: side view (towards starboard) and top view.

The vessel image file has to obey the following requirements:

1 The vessel data have to be in an ASCII file generated by Excel, Notepad or similar tools.

2 The file head includes Overall length (LOA), Overall width, Overall height and

Stern to Frame 0 (AP) data in metres.

3 Profile (side view) data in X and Z coordinates in metres, related to the origin.

Coordinates are specified clockwise from a point aft of the origin, and the last coordinate has to equal the first coordinate to form a closed polygon.

4 The top view data in X and Y coordinates in metres. The first coordinate has to be aft of the origin along the centre line. Successive coordinates are specified clockwise, and the last coordinate has to equal the first to form a closed polygon.

Vessel image files may be created by Kongsberg Seatex AS upon customer request. GA drawings or similar is required to create vessel image files.

A typical example of a vessel data file is illustrated.

Figure 17 Example GA drawing of multi-purpose vessel

G210-14/3.0

Kongsberg DPS 232

Figure 18 Example of vessel shape in user text file

Figure 19 Example vessel shown in Vessel Geometry view

In the example, only the port side of the vessel top view is defined in the file. Symmetry is assumed, so this is sufficient to draw a symmetric vessel shape. If the vessel is not symmetric, use the section code %Top view coordinates in (X,Y) [m]

Complete and give the coordinates along the complete shape, defined clockwise.

G210-14/3.0

It is possible to define cutouts within the profile or top view polygons. For profile cutout, use %Profile cutout n , where n identifies the cutout.

5.4.3

Vessel description

The Vessel Description view contains information about the vessel needed for identification purposes, e.g. finding the correct configuration file at a later stage.

Figure 20 Vessel Description view

Vessel name

The name of the vessel. An empty name field is not allowed. The default value is

VESSEL .

Vessel owner

The name of the vessel owner (optional).

Country of origin

The name of the vessel's country of origin (optional).

MMSI

The MMSI assigned to the vessel. Default value is 0.

5.5 Sensors configuration

5.5.1

GNSS geometry

The lever arm vector from the Origin to the GNSS antenna has to be measured or calculated based upon drawings or previously measured points, and entered into the configuration.

How to set up antenna location

1 Set the antenna location coordinates for the GNSS antenna.

2 Check that the antenna has been located on the expected spot in the vessel shape.

If not, check the signs and the co-ordinates entered for the GNSS antenna , the vessel dimensions and the entered location of Origin.

G210-14/3.0

Figure 22 GNSS sensor geometry configuration view

5.5.2

GNSS processing

For operations with weak satellite geometry, the use of height aiding and/or a lower elevation mask, may improve the position availability.

Available height aiding mode values are Filter and Off . The height aiding mode is normally set to Filter. In height aiding mode Filter, the processing software will use the averaged antenna height measurement as a contribution to the position solution. For operations with varying height, height aiding mode should be set to Off.

The elevation mask has a default value of 10 degrees, which is the recommended setting for most scenarios. Under special conditions the Elevation mask might be changed in order to improve the satellite geometry or reduce multipath. The recommended value range is from 7 to 15 degrees.

The position integrity status indication (Safe, Caution, Unsafe) is based on the position

Accuracy level . The vessel's operational mode may require the accuracy level to be modified. The default value is 10 m. If the EPE value is larger than the accuracy level, the system integrity status is indicated as Unsafe.

The Ionosphere activity value is used to indicate the level of ionospheric activity.

Available values are Normal , Medium and High . The default value is Normal .

Note

During periods with increased ionospheric activity, this value should be set to High for optimized system performance. Distant single frequency reference stations will then have less influence on the position calculations.

G210-14/3.0

5.5.3

SBAS tracking

In the SBAS tracking view it is possible to set up

Automatic or Manual tracking of SBAS satellites.

When Automatic tracking is selected, the GNSS receiver chooses which SBAS satellites to track. (This option is currently unavailable.)

In Manual mode the user must set up which SBAS satellites to use. If two SBAS satellites are selected, the system will automatically use data from the best satellite. If only one SBAS satellite is selected, only correction data from this satellite will be used in the computations.

Figure 24 view

SBAS tracking

If no specific SBAS satellite is selected, the system will select and use data from the best of the available satellites. If the selected SBAS satellite is not available, the system will not use the SBAS correction data in the computations. Maximum two SBAS satellites may be tracked by the GNSS receiver.

5.5.4

HP/XP/G2

In the HP/XP/G2 view it is possible to control the use of high precision services.

These features are switched off by default and have to be enabled by an operator.

5.5.5

IALA

The IALA view offers IALA beacon receiver configuration. The Search mode list box allows the

DGNSS interface to switch IALA beacon off, search for information automatically, or set the frequency and

MSK bit rate manually.

By default, IALA search mode is set to Auto.

Figure 26 IALA view

5.5.6

RTK

This setting can be changed to optimize the performance in RTK mode. The Glonass option has three selections: Off, RTK and Float and Float only. The default setting is RTK and Float.

How and when to change the default RTK settings

1 The Glonass option for the RTK solution can be changed from the default setting

RTK and Float to Float only or Off by pulling down the Glonass option drop-down list.

The RTK and Float selection is recommended used under conditions where the RTK correction source is known (own local reference station). The Float only selection is used when the system has problems with getting an RTK solution. The Off selection is used when the RTK corrections include only two-frequency GPS corrections.

Figure 27 RTK view

5.6 Monitoring points configuration

The system supports up to eight user definable monitoring points. These are defined in the Monitoring Points view.

As soon as a monitoring point has been defined, its location is indicated in the vessel outline for easy visual verification. The monitoring points are given relative to Origin

(positive forward, towards starboard and down). The position of a monitoring point relative to the Origin is indicated in the drawing when the cursor is over the monitoring point.

If a monitoring point appears incorrect, check the signs and the coordinates input for each monitoring point, the vessel dimensions and the entered location of Origin.

G210-14/3.0

Kongsberg DPS 232

Figure 28 Monitoring Points view

To add a monitoring point, select the Add button in the upper left corner of the view and drag the symbol to the correct location on the vessel.

The selected monitoring point coordinates are shown at the bottom of the view.

To get exact coordinates from Origin to each monitoring point, each monitoring point has to be measured or calculated based upon drawings or previously measured points, and entered into the software manually. To delete a point, select the wanted point in the list and then press the X button in the top left corner.

When the Add button is pressed, red lines will be displayed on the screen to help placing the new point. Co-ordinates will also be displayed to help placing the monitoring point.

6 Commissioning

6.1 System Verification tool

The equipment will be commissioned after installation. A trained operator will fill out the Commissioning Report with the necessary parameters. A copy of the Commissioning

Report should be inserted in the Site Manual , which is supplied with the product.

The system is delivered with a System Verification tool to assist in analysing the logged data. The tool will process a data file, create a PDF file containing the results and store the logged file, the result information and the configuration files in an archive compatible with popular archive programs such as WinZip.

The tool is intended for use when the vessel is in the harbour, as it assumes that the antenna is not moving.

Figure 52 System Verification tool

How to use the System Verification tool

1 Start the System Verification tool from the application menu by selecting

Tools→System Verification .

G210-14/3.0

2 The vessel name is automatically entered into the Vessel name text box based on the

NAV Engine configuration, but can be changed.

3 Enter the correct serial number of the Processing Unit.

4 Click the browse button next to the Logged data file field to select a log file to analyse. The tool will open the appropriate root folder for log files created by the

NAV Engine. The selected file will be inspected, and the tool will indicate if the file may be processed or not.

The CTP log file has to contain ZDA, GGA and GSV NMEA telegrams in order to produce a valid CTP report. The default NAV Engine configuration sets up

TelegramOut number 16 for CTP logging. The files from this output are named mmddHHMM.l16.

5 The reference position will be read from the file if available. Select the Edit check box to enter or modify the reference position manually.

6 The Include system configuration check box is selected by default. It is recommended to leave this box selected.

7 If a USB media is detected, it is automatically selected as the target of the System

Verification archive. A Switch button will appear if multiple USB media are detected.

Note

If a USB stick is not inserted, the archive will be stored in a temporary location on the local disk. In this case, the archive will only be available for restore until the next reboot.

8 Click the Start button to start the verification. A progress bar is displayed during the processing.

9 Click the X button in the upper right corner to close the tool.

The created archive contains full system configuration, the verification log file and a summary report in PDF format.

The system configuration stored in the archive created by the System Verification tool may be restored by the Restore Configuration tool.

How to install the antenna

After a site has been selected, install the antenna as follows.

1 Verify that the thread on the mount does not extend more than 7/8" (22 mm) to ensure the plastic inside the antenna receptacle is not damaged when the mount is inserted. If it extends further than 7/8" (22 mm), add two jam nuts to shorten the exposed thread, ensuring the nuts are well-tightened.

Align the mount thread with the metal adapter on the bottom of the antenna and rotate the antenna clockwise until it is securely screwed to the mount. Using a wrench, tighten the adapter to the mount.

3 Remove the dust cap from the antenna's

N-Type connector.

4 Attach the male N-Type connector of the coaxial cable to the antenna's N-Type.

Note

The metal adapter on the bottom of the antenna is fixed in place. Do not attempt to remove it.

5 Attach the end of the coaxial cable to the antenna input port of the receiving device.

All NovAtel GNSS receivers provide the necessary power through their antenna

RF connectors.

14 xxxx = Differential reference station ID, 0000-1023

15 *hh = Checksum.

Telegram options

The telegram output configuration contains a list of options (see Telegram out properties,

Options drop-down list).

Some older external systems may not handle correction age values above 9.9 s. To avoid such conflicts, it is possible to limit the correction age to 9.9 s in the GGA telegram by checking the Limit correction age to 9.9 seconds in GGA . The default is to report the actual correction age.

It is possible to output the last valid position but flag as invalid by checking the Use last valid position option. The default is to stop the telegram output when no new data is available.

The NMEA standard allows a maximum of 12 satellites in the GGA message. As many systems are able to use more than 12 satellites in the position solution, the actual number of satellites used may be reported by checking the Allow more than 12 satellites in GGA message option.

It is possible to set the GPS quality indicator to 5 (Satellite system used in RTK mode, floating integers) when converged HP, XP or G2 solution is available and no GNSS corrections are available. This is done by checking the Set GGA quality inticator to

5 if converged HP, XP or G2 option. The default is 1 if no GNSS corrections are used in the position solution.

It is possible to use the DQI as the quality indicator of the GGA message, by checking the Use DQI (0–9) as GGA quality indicator option. Note that when this option is checked, the message talker ID is forced to 'DP' for all GGA messages through the selected output port. The default is to use the GPS quality indicator as described in the NMEA 0183 standard, and use the talker ID selected for the system.

A.7 GLL messages

The GLL message presents latitude and longitude of vessel position, time at position fix and status. The message is as specified in NMEA 0183 version 3.0. The message structure is as follows:
