1 INTRODUCTION

1.1 About this Manual

This manual, together with the Operator Manual, provides in-depth information to facilitate installation of the Saab TransponderTech R4 Combined AIS & Navigation System.

The R4 Combined AIS & Navigation System is available in two system configurations: GPS and DGPS. This manual is valid for both configurations.

1.2 System Overview

Figure 1-1 shows an overview of the R4 Combined AIS & Navigation System. The R4 Combined AIS & Navigation System comes in two configurations: GPS and DGPS. Both configurations feature an R4 Display and R4 AIS Transponder. The GPS configuration also features an R4 GPS Navigation Sensor and an MGA-2 GPS antenna, while the DGPS configuration features an R4 DGPS Navigation Sensor and an MGL-4 combined GPS/Beacon antenna.

The R4 Display provides a graphical interface to the system. Via the display it is possible to plot the location of other ships, base stations, aids to navigation and the active route. Vessels can be listed sorted by range or bearing. The display also makes it possible to create, edit and modify routes and waypoints, navigate following a route, send and receive messages, view sensor data, perform setup as well as supervise the systems status.

The R4 AIS Transponder consists of a radio transceiver unit, a GPS receiver and a controller unit. The transceiver consists of one transmitter and three independent VHF receivers, two tunable TDMA receivers and one DSC receiver. The transmitter alternates its transmissions between the two operating TDMA channels and can also be used to reply to a DSC interrogation (ITU-R M.825-3, Annex 1). The controller unit creates and schedules data packets (containing dynamic, static and voyage related data) for transmission based on the IMO performance standard for AIS.

The R4 AIS Transponder shall be connected to the ship‘s sensors as required by the installation guidelines published by IALA. The R4 AIS Transponder can interface external navigation and presentation systems that support required IEC 61162-1 sentences as set out in this manual. The R4 Transponder is prepared for connection to Long Range systems like Inmarsat C.

The R4 GPS Navigation Sensor features a high-precision GPS receiver, capable of receiving WAAS, EGNOS and MSAS differential corrections. The R4 DGPS Navigation Sensor has all the features of the GPS Sensor, as well as a dual channel beacon receiver for reception of IALA radio beacon DGPS corrections. Both the GPS and the DGPS Navigation Sensor perform continuous RAIM calculations according to the IEC 61108-1 (2nd edition) standard (see Ref. [5]).

The R4 Navigation Sensor is connected to an antenna, either an MGA-2 GPS antenna or an MGL-4 combined GPS/Beacon antenna. The MGL-4 antenna is capable of receiving and interpreting both radio beacon and satellite signals.

4.5.4 Cabling

Use the included R4 Power and Data cable, marked ―7000 109-011‖, to connect to the R4 Navigation Sensor to the power source, the R4 Display and any external systems or sensors. Note that the cable has a maximum bending radius of 15 cm. Connect the cable‘s 18 pin male ConXall connector to the female 18 pin connector on the back of the R4 Navigation Sensor. Wire the open end of the cable as described in section 5.3 and Appendix [A.11].

Connect the antenna to the R4 Navigation Sensor, following the instructions in section 4.8.

Note: The power and data cable for connecting to the R4 Navigation Sensor and the signal cable for connecting to the R4 Display both use 18 pin connectors. Make sure they are not interchanged! The R4 Sensor power and data cable is marked with ―7000 109-011‖ and can also be identified by the fact that all 18 pins are mounted in the male connector.

Note: The R4 Navigation Sensor provides 5 VDC across its antenna port. The antenna shield as well as the R4 Navigation Sensor power and data cable shield and Signal GND lines are connected to the negative terminal of the 24V DC power supply. Connecting to the ship‘s structure or incompatible devices may result in damage to equipment.

Note: The Chassis of the R4 Navigation Sensor is not connected to any internal ground and may thus be connected to the ship‘s structure if desired.

4.5.5 Power Supply

The R4 Navigation Sensor can be connected to an emergency power source. If connected to an emergency battery, a re-calculation must be made for the battery capacity. For power consumption, see section 8.4.

The R4 Navigation Sensor is designed to operate on 24 VDC. The nominal power used is 2.7 W. The R4 Navigation Sensor shall be externally fused (slow blow fuse) with a 1 A fuse.


4.6 Mount the R4 Transponder’s VHF antenna

The R4 Transponder shall be connected to a VHF antenna.

The R4 AIS Transponder, like any other shipborne transceiver operating in the VHF maritime band, may cause interference to a ship‘s VHF radiotelephone. Because AIS is a digital system, this interference may occur as a periodic (e.g. every 10 second) soft clicking sound on a ship‘s radiotelephone. This effect may become more noticeable when the VHF radiotelephone antenna is located close to the AIS VHF antenna and when the radiotelephone is operating on channels near the AIS operating channels (e.g. channels 27, 28 and 86).


Installation Manual

MOUNTING

7000 109-153, B Page 36

Attention should be paid to the location and installation of different antennas in order to obtain the best possible efficiency. Special attention should be paid to the installation of mandatory antennas like the AIS antennas.

So, installing the AIS VHF antenna is also a crucial part of the system installation. How and where you install your AIS VHF antenna and cable will affect its efficiency.

4.6.1 Antenna location

Location of the mandatory AIS VHF antenna should be carefully considered. Digital communication is more sensitive than analogue/voice communication to interference created by reflections in obstructions like masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize the interference effects. Installing the VHF antenna for AIS on a vessel is a compromise between the following items:

Antenna type

Antenna separation

Clear view of the horizon

Antenna height

4.6.2 Antenna type

The AIS VHF antenna should have omni directional vertical polarisation providing unity gain.

4.6.3 Antenna separation

The AIS transponders are using simplex channels at frequencies on the high side of the marine mobile band (AIS channel A = 2087 (161.975 MHz) and AIS channel B = 2088 (162.025 MHz)). These channels are close to the duplex channels used for shore to ship marine communication. The AIS VHF antenna should be separated as much as possible from the voice VHF installations used for main communication to avoid unnecessary interference.

There should not be more than one antenna on the same level. The AIS VHF antenna should be mounted directly above or below the ship‘s primary VHF radiotelephone antenna, with no horizontal separation and with a minimum of 2 meters vertical separation. If it is located on the same level as other antennas, the distance apart should be at least 10 meters.

The AIS VHF antenna should be installed safely away from interfering high-power radiating sources like radar and other transmitting radio antennas, preferably at least 3 meters away from and out of the transmitting beam.

4.6.4 Clear view of the horizon

The AIS VHF antenna should be placed in an elevated position that is as free as possible with a minimum distance of 2 meters in horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large


Installation Manual

MOUNTING

7000 109-153, B Page 37

vertical obstruction. The objective for the AIS VHF antenna is to see the horizon freely through 360 degrees.

4.6.5 Antenna height

The AIS is using VHF radio frequencies, which propagation characteristics are close to line of sight. The higher antenna location is, the longer the range will be.

4.6.6 Cabling

The cable should be kept as short as possible to minimise attenuation of the signal. Double shielded coaxial cable equal or better than RG214 is recommended to minimise the effects from electromagnetic interference from high power lines, radar or other

radio transmitter cables, see Appendix A.7 – VHF-cable selector.

4.6.7 Cable mounting

Coaxial cables should be installed in separate signal cable channels/tubes and at least 10 cm away from power supply cables. Crossing of cables should be done at right angles (90°).

Coaxial cables should not be exposed to sharp bends, which may lead to a change of the characteristic impedance of the cable. The minimum bending radius should be 5 times the cable's diameter.

All outdoor installed connectors should be weatherproofed, e.g. with shrink tubing, watertight seal tape or butyl rubber tape and plastic tape sealing, to protect against water penetration into the antenna cable.

Secure the cable properly, close to the cable ends.

4.6.8 Grounding

Coaxial down-leads must be grounded. The coaxial shielding screen should be connected to ground at one end.

4.7 Mount the R4 Transponder’s GPS antenna

The R4 Transponder shall be connected to a GPS antenna type MGA-2, AT575-68 or equivalent. 5V DC is supplied through the antenna lead for the antenna preamplifier.

Attention should be paid to the location and installation of the different antennas on the ship in order to obtain the best possible efficiency. Special attention should be paid to the installation of mandatory antennas like the AIS antennas.

So, installation of the GPS antenna is a crucial part of the system installation. How and where you install your GPS antenna and cable will greatly affect its sensing efficiency.


Installation Manual

MOUNTING

7000 109-153, B Page 38

4.7.1 Antenna location

The GPS antenna must be installed where it has a clear view of the sky. The objective is to see the horizon freely through 360 degrees with a vertical observation of 5 to 90 degrees above the horizon. Small diameter obstructions, such as masts and booms, do not seriously degrade signal reception, but such objects should not eclipse more than a few degrees of any given bearing. Do not mount the antenna in the top of a mast or tower, as this may degrade the COG and SOG readings.

Locate the GPS antenna at least 3 meters away from and out of the transmitting beam

of high-power transmitters such as S-Band Radar (typically 15° vertically from the

array‘s centre point) and/or Inmarsat systems (A, B, C, or M; typically 10º from the array‘s centre point in any of the possible transmitting directions).

Locate the GPS antenna at least 3 meters away of a HF or VHF radios or their antennas. This includes the ship‘s own AIS VHF antenna if it is designed and installed separately.

4.7.2 Cabling

The gain of the GPS antenna built-in pre-amplifier shall match the cable attenuation. The resulting installation gain (pre-amplifier gain - cable attenuation) shall be within 0 to 26 dB. A minimum value of 10 dB is recommended for optimum performance.

Double shielded coaxial cable is recommended. The coaxial cable should be routed directly between the GPS antenna and the R4 Transponder GPS connector in order to reduce electromagnetic interference effects. The cable should not be installed close to high-power lines, such as radar or radio-transmitter lines or the AIS VHF antenna cable. A separation of one meter or more is recommended to avoid interference due to RF-coupling. Crossing of antenna cables should be done at 90 degrees to minimise magnetic field coupling.

Recommendations on cable types and lengths can be found in Appendix A.8 – GPS Cable Selector.

4.7.3 Cable mounting




Secure the cable properly, near the cable ends.


Installation Manual

MOUNTING

7000 109-153, B Page 39

4.7.4 Grounding

Coaxial down-leads must be used. The coaxial shielding screen should be connected to ground at one end.

4.8 Mount the GPS or DGPS Navigation Antenna

The R4 Navigation Sensor should be connected to the included antenna, which in the GPS configuration is a MGA-2 GPS antenna and in the DGPS configuration is a MGL-4 combined GPS/Beacon antenna.

Attention should be paid to the location and installation of the different antennas on the ship in order to obtain the best possible signal reception. Installation of the Navigation Sensor‘s antenna is a crucial part of the system installation. How and where you install your antenna and cable will greatly affect its sensing efficiency.

4.8.1 Antenna Location

Mount the MGA-2 or MGL-4 antenna at a location with a clear, unobstructed view of the sky. For best beacon reception performance, mount the MGL-4 antenna so that the center of the black gasket is at least 8 cm (3 in) above any metal surface.

Local noise generated by your vessel or surroundings may affect your navigation system performance. To minimize this impact, you should locate the antenna outside the path of any radar beam, away from any transmitting antennas, and away from any other sources of interference such as motors, solenoids and other electronics. Do not, however, mount the antenna in the top of a mast or tower, as this may degrade the COG and SOG readings.

The MGA-2 and MGL-4 uses a 1-14-UNS thread for mounting. Mount the antenna on a standard US 1‖ 14 thread pipe or other standard antenna mount (not included).

Note: Antennas threaded onto a mount should be tightened only by hand. Do not tighten the antenna by turning on the antenna cover, instead hold the mounting shaft located at the bottom of the antenna and tighten by hand. Do not thread the shaft deeper than ¾. Do not use tools to install the antenna on the shaft as this may cause damage. Damage caused by over tightening is not covered by warranty.

Note: Once the system has been correctly mounted and connected, it is possible to monitor the R4 Navigation Sensor receiving performance via the graphical interface of the R4 Display. This information can be used to locate the optimum placement of the antenna. This is further described in section 6.11.

4.8.2 Cabling

The maximum allowable cable loss is 18 dB for the MGA-2 and MGL-4 antennas. The maximum cable length depends on the attenuation the cable and the chosen antenna. As an aid to cable selection, refer to Appendix [A.9].

Double shielded coaxial cable is recommended. The coaxial cable should be routed directly between the antenna and the R4 Navigation Sensor in order to reduce electromagnetic interference effects. The cable should not be installed close to high-power lines, such as radar or radio-transmitter lines or any AIS VHF antenna cable. A separation of one meter or more is recommended to avoid interference due to RF-coupling. Crossing of antenna cables should be done at 90 degrees to minimize magnetic field coupling.

4.8.3 Cable Mounting




Secure the cable properly, near the cable ends.

Connect the antenna to the R4 Navigation Sensor before you apply power to it.

4.8.4 Grounding

The MGA-2 and MGL-4 antennas do not require any antenna ground connection.

The red LED marked ―PWR‖ indicates, when lit, that power is applied to the R4 Navigation Sensor.

GPS LED

The yellow LED marked ―GPS‖ indicates, when continuously lit, that the R4 Navigation Sensor has obtained a solid GPS lock.

CORR LED

The yellow LED marked ―CORR‖ indicates, when continuously lit, that the R4 Navigation Sensor has achieved a solid radio beacon lock or a SBAS lock with a bit error rate (BER) better than 150. If the SBAS BER is higher than 150 but the receiver is still locked, this LED will blink showing that the lock is marginal. This LED is also lit while using external DGPS corrections input through the User 1 port.

DGPS LED

The green ―DGPS‖ LED indicates that the R4 Navigation Sensor has achieved a differentially corrected position. It is continuously lit when the range residuals in the position solution have settled below a threshold value.

6.2.3 R4 Transponder LEDs

The following LEDs, located on the front of the R4 Transponder, indicates its current status and radio link activity.

Green LED

The green LED indicates that power is applied to the R4 transponder.

Yellow LED

A flashing yellow LED indicates that the R4 Transponder is receiving data.

Red LED

A flashing red LED indicates that the R4 Transponder is transmitting on the radio link (transmission starts approximately 1 minute after power on).

6.3 System Power Up

The system is turned on by applying power to the R4 Transponder, R4 Navigation Sensor and the R4 Display. The R4 Transponder and R4 Navigation Sensor does not have a switch for turning them on, but instead starts directly once power is applied. The R4 Display is turned on, by pressing the POWER key. The LEDs on the R4 Display should blink momentarily indicating that it is starting.

When the system is started, there may be some alarms displayed depending on which sensors that have been connected to the system. If any alarms are displayed, take notice of the alarms displayed and then acknowledge them by pressing the ENTER key until the alarms are not displayed any more.

The R4 Navigation Sensor should—when correctly installed—provide a position quickly, within approximately 60 seconds. SBAS lock requires approximately 30 seconds to acquire, and radio beacon lock 60 seconds. It can however take up to 5 minutes for a full ionospheric map to be received from SBAS, and optimum accuracy obtained. The status of the Navigation Sensor is indicated by its LEDs, as was described in section 6.2 above.

To continue the system configuration, see the following sections.

6.5 R4 Transponder Connection Lost Troubleshooting

The R4 Display continuously monitors the serial connection to the R4 Transponder. If the

connection is lost or never established, the R4 Display will show the icon and activate one of the alarms ―R4 Display Lost Connection to R4 Transponder‖ or ―R4 Transponder Lost Connection to R4 Display‖. There are three possible malfunctions:

1. The R4 Transponder does not receive the R4 Display data but the R4 Display receives the R4 Transponder data. The alarm ‖R4 Transponder Lost Connection to R4 Display‖ will be raised.

2. The R4 Display does not receive the R4 Transponder data. The alarm ‖R4 Display Lost Connection to R4 Transponder‖ will be raised.

3. The communication between the R4 Display and Transponder does not work in any direction. The alarm ‖R4 Display Lost Connection to R4 Transponder‖ will be raised.

Perform the following steps to troubleshoot the condition:

1. Verify that power is correctly applied to the R4 Transponder, indicated by the green LED being lit on the Transponder. If not, check the wiring of the positive and negative power wires.


Installation Manual


7000 109-153, B Page 54

2. Verify the wiring of the interconnection between the R4 Display and R4 Transponder. Ensure that the TX lines of the R4 Transponder port on the R4 Display are connected to the RX lines of the Display port on the R4 Transponder, and vice versa. Ensure that TX-A is connected to RX-A, TX-B to RX-B and so on, as illustrated in Table 6-1.

See the wiring diagram in appendix [A.11].

3. The View Raw Data view can be used to monitor the traffic on the R4 Transponder port, which gives information on if any data is received from the R4 Transponder. The View Raw Data view is described in section ―Port Rate Config‖ in the Reference chapter of the Operator‘s Manual. If the View Raw Data screen displays garbage characters, it is possible that the A and B wires of the interconnection between the R4 Display and R4 Transponder have been interchanged. See step 2 above. If this does not help, contact your R4 Combined AIS & Navigation System dealer.

6.6 GPS Connection Lost Troubleshooting

The R4 Display continuously monitors the serial connection to the R4 Navigation Sensor. If the connection is lost or never established, the R4 Display will activate the alarm ―GPS

Connection Lost‖ and show the status icon. In this state, the Display can not communicate with the Navigation Sensor. Perform the following steps to troubleshoot the condition:

1. Verify that the correct cables have been connected to the R4 Display and to the R4 Navigation Sensor. Note that both cables use 18-pin Conxall male connectors. The cable marked ―7000 108-133‖ (with 13 pins mounted in the connector) should be connected to the R4 Display. The cable marked ―7000 109-011‖ (with 18 pins mounted in the connector) should be connected to the R4 Navigation Sensor.

2. Verify that power is correctly applied to the R4 Navigation Sensor, indicated by the red LED marked ―PWR‖ being lit on the Sensor. If not, check the wiring of the positive and negative power wires.

3. Verify the wiring of the interconnection between the R4 Display and R4 Navigation Sensor. Ensure that the TX lines of the R4 Sensor port on the R4 Display are connected to the RX lines of the System port on the R4 Navigation Sensor, and

4. Verify the communication rate of the R4 Sensor port on the R4 Display. It should be set to 57600 bps. The communication rate can be seen in the Port Rate Config view, as described in section ―Port Rate Config‖ in the Reference chapter of the Operator‘s Manual.

5. The View Raw Data view can be used to monitor the traffic on the R4 Sensor port, which gives information on if any data are received from the R4 Navigation Sensor. The View Raw Data view is described in section ―Port Rate Config‖ in the Reference chapter of the Operator Manual. If the View Raw Data screen displays garbage characters, it is possible that the A and B wires of the interconnection between the R4 Display and R4 Navigation Sensor have been interchanged. See step 3 above. If this does not help, contact your R4 Combined AIS & Navigation System dealer.

6.7 Position Data Lost Troubleshooting

The alarm ―Position Data Lost‖ indicates that no valid positioning information is received from the R4 Navigation Sensor. If the alarm ―GPS Connection Lost‖ also is active, then the communication with the Navigation Sensor is not functioning and should be resolved first, as described in section 6.6 above.

When only the ―Position Data Lost‖ alarm is active, this indicates that the R4 Navigation

Sensor is not receiving a good enough GPS satellite signal to produce a position. The status icon will be shown. Check the connection of the antenna cable to the Navigation Sensor and to the MGA-2 or MGL-4 antenna. Also check the installation and placement of the antenna, and ensure that it conforms to that specified in section 4.6.1. The Satellite Info view, described in section 6.11.2, can give further details on received position data.

6.11.2 Check Navigation Position

1. Enter Navigate mode by pressing Mode key and then press function key NAVIGATE followed by Position. The Position view should be displayed, as illustrated below:

2. Verify that latitude and longitude are displayed, and that an icon in the status bar indicates that valid position information is received. This is indicated by one of the icons (valid uncorrected position), (position corrected using radio beacon differential corrections), (position corrected using external corrections) or (position corrected using SBAS differential corrections).

To verify the quality of received GPS and radio beacon signals for R4 Navigation sensor, the following steps can be performed. The signal strength is measured as a signal to noise (SNR) ratio. (The SNR is the strength of the signal above the noise floor.) The higher the SNR, the better your receiver is receiving the signal. The optimum antenna location will be a position where your average SNR is highest. You should turn on all equipment that you intend to use during normal operation when locating the best position for the antenna.

3. To verify the signal strength of received GPS signals, press the function key Satellite Info when in the Position view. The following view should be displayed.


Installation Manual


7000 109-153, B Page 74

The Elevation field presents each satellite‘s height in degrees above the horizon. The Azimuth field presents the satellite‘s angular horizontal position, counted clockwise from the north. The R4 Navigation Sensor is more precise when it receives satellites widely spread across the sky, at various elevations.

The SNR column shows the SNR for each received satellites signal. A good antenna installation should receive three or more satellites with SNR values above 50. If few satellite signals are received, and / or the received signals have low SNR ratings, this could indicate that the GPS reception is poor and that the position of the antenna needs to be adjusted. See section 4.8.1 for antenna placement guidelines.

4. If installing a DGPS configuration with a R4 DGPS Navigation Sensor, it is also possible to monitor the received radio beacon signal strength. Follow the steps below.

Go back to the Position view by pressing Esc and then press function key Beacon

Status. Use to scroll down to the second page of information so the SNR value can be inspected. The following view should be displayed.


Installation Manual


7000 109-153, B Page 75

The observed radio beacon SNR value should be interpreted as follows:

SNR Description Data Throughput

>25 Excellent 100% data throughput

20 to 25 Very Good 100% data throughput

15 to 20 Good Good data throughput up to 100%

10 to 15 Stable Moderate to good data throughput

7 to 10 Intermittent Low data throughput

<7 No Lock No data throughput

If the received signal has a low SNR rating, this could indicate that the radio beacon reception is poor and that the position of the Combined GPS/Beacon antenna needs to be adjusted. See section 4.8.1 for antenna placement guidelines.


Installation Manual


7000 109-153, B Page 76

6.11.3 Check Transponder‘s Internal GPS Status

With an R4 Combined Transponder with sw version R4C 5.2.0 or higher it is also possible to monitor the transponder‘s internal GPS reception.

This is done by pressing MODECONFIGPAGESystem InfoTranspon. GPS. The Transponder GPS Status view is shown:

The Elevation field presents each satellite‘s height in degrees above the horizon. The Azimuth field presents the satellite‘s angular horizontal position, counted clockwise from the north.

The SNR column shows the SNR for each received satellites signal. A good antenna installation should receive three or more satellites with SNR values above 50. If few satellite signals are received, and / or the received signals have low SNR ratings, this could indicate that the GPS reception is poor and that the position of the antenna needs to be adjusted. See section 4.7.1 for antenna placement guidelines.

6.12 Adjusting Other System Settings

The R4 Combined AIS & Navigation System is fully operational once correctly mounted, connected and configured, as have been described in this document. However, it may be desired to adjust some system characteristics to the operating environment and the preferences of the users of the system. System settings that can be adjusted includes—among others—used waypoint pass criterion, measurement units, cross-track error limit and enabled and disabled alarms. For information on adjustable parameters please refer to the Operator‘s Manual, section ―Adjusting Settings‖ in the Reference chapter.

7.2 ECDIS / Pilot systems interfaces

The two high-speed ECDIS/Pilot ports can be used to connect systems like ECDIS, ECS, ARPA-radar or stand-alone AIS displays and pilot carry aboard equipment.

The ECDIS / Pilot systems interface supports the following application functions:

Navigation data of the own station.

Automatic exchange of navigation data between vessels and between vessels and VTS stations and networks.

Communication ship to ship and ship to shore in broadcast or addressed mode.

Input of certain static and voyage related data of the own station, e.g. destination, ship size and cargo.

Interrogation of remote transponder for specific data.

Output of certain system and station data.

Depending on the chart system implementation the user can be provided a powerful tool to display the own ship data as well as other ships data (including navigation, static and voyage related ship data) within radio range. A chart system that fully exploits the transponder features will in addition provide application information communicated by binary messages and text communication (possibly by ―clicking‖ predefined text strings in a communication window) between ships and shore stations.

VTS centres using a transponder system may use the same facilities as described above possibly added with additional features such as Navigation Reports and Broadcast of Radar Targets. The latter enables ships receiving this data to get the VTS radar information on display on the own ships chart system. The system allows for local applications to exchange data by using the binary messages yet not impairing any of the basic AIS functions.

Input messages are received from the application system, e.g. Electronic Chart System. The transponder system processes the input data and executes the appropriate tasks and events such as transmission on the VHF data link.

7.3 Sensor interfaces

The R4 Transponder unit has three interfaces (meeting IEC 61162-1 and 61162-2) for position, bottom track (BT) speed, heading and rate of turn (ROT) sensors.

In general, sensors installed in compliance with other carriage requirements of SOLAS Chapter V should be connected to the AIS. Although the fact that AIS comes on board does NOT establish a need to install additional sensors above carriage requirements.

The sensor information transmitted by the R4 Combined AIS & Navigation System should be the same information being used for navigation of the ship.

7.3.1 Sensor input data and formats

The three sensor ports support data sentences input from various types of ship sensors. The input data and format are shown in Table 7-3. Details of each sentence can be found in Ref. [2].

7.3.2 Position (GGA, GLL, GNS, RMC, DTM etc.)

GNSS position sensors normally have IEC 61162 outputs suitable for directly interfacing the R4 Transponder. However, it is important to note the following:

The Geodetic Datum of the position data transmitted by the sensor shall be WGS84 and the IEC 61162 DTM sentence should be configured.

R4 AIS Transponder is able to process two reference points for its antenna position, one for external and one for an internal sensor. Each antenna‘s reference point needs to be input to the AIS via the R4 Display (see section 6.8.2). The R4 AIS Transponder automatically selects the position source with the highest priority available. The priority scheme is defined by the AIS standard (Ref. [6]). The appropriate information will be used accordingly.

7.3.3 Heading (HDT)

All ships will not carry a gyrocompass according to IMO A.526. However, if a gyrocompass, which provides heading information (and possibly ROT data, see section 7.3.4), is available and it includes an IEC 61162 interface, it shall be connected to the R4 Transponder.


Installation Manual


7000 109-153, B Page 86

If the ship‘s gyrocompass does not provide an IEC 61162 output, a converter unit (e.g. stepper to NMEA) will be needed to connect to the R4 Transponder.

7.3.3.1 Heading Sensor Fallback Condition

The R4 transponder automatically selects the heading source with the highest priority, based on the talker identifier of the sensor sentence. The priority is according to table below.

Table 7-4. Heading sensor fallback priority

Talker Id Priority

$HE--- Highest Priority

$HC---

$----- Any talker identifier. Lowest Priority

7.3.4 Rate of Turn (ROT)

All ships will not carry a Rate-of-Turn (ROT) Indicator according to IMO A.526. However, if a Rate-of-Turn Indicator is available and it includes an IEC 61162 interface, it shall be connected to the R4 Transponder.

7.3.4.1 Other ROT sources

If ROT information is not available from a Rate-of-Turn Indicator, it may (optionally) be derived through:

The gyrocompass itself (see section 7.3.3)

Other external sources giving ROT or heading

The AIS itself based on external heading

However, in any of the above cases, the AIS will only indicate the rate of turn direction (not the ROT value).

ROT data shall not be derived from COG information.

7.3.4.2 No ROT available

If no ROT information is available, the AIS will transmit default values indicating not available. ROT data will not be derived from COG information.

7.3.4.3 ROT sensor fallback conditions

The R4 Transponder automatically selects the ROT source with the highest priority available. The priority scheme is defined by the AIS standard (Ref. [6]).


Installation Manual


7000 109-153, B Page 87

7.3.5 Log (VBW)

If a Bottom Track (BT) Log (hereafter referred to as Speed Log) for Speed Over Ground (SOG) is available, it shall be connected to the R4 Transponder.

The R4 Transponder will derive Course Over Ground (COG) from this information.

Note that the R4 Transponder needs heading information to be able to derive SOG and COG from Speed Log data. The R4 Transponder will use the Speed Log as source for SOG and COG as long as heading information is available.

If heading information is not available, Speed Log data will not be used. In this case the R4 Transponder will use the position sensor as source for SOG and COG.

7.4 Long Range equipment interface

7.4.1 Long Range communication system

The AIS‘ Long Range function needs a compatible long-range communication system (e.g. Inmarsat-C or MF/HF radio).

If this is available, a connection between that communication system and the R4 Transponder can be made. This connection is needed to activate the LR function of the AIS. Its input/output port must meet the requirement of IEC 61162-2.

7.4.2 Long Range function

The Long Range reply can be set in either:

automatic mode (AUTO)

manual mode (MANUAL) or

manual mode using external application (EXT APPL).

The Long Range reply, when in AUTO mode, is made as soon as a request is received on the Long Range communication port.

The Officer on the Watch must approve the Long Range reply, when in MANUAL mode, by a means of pressing a keyboard button on the display before the reply is performed.

The Long Range reply, when in EXT APPL mode, is made by the display upon reception of confirmation / acknowledgement from the external application via the high-speed ports. The external application acknowledge the interrogation by returning the LRF sentence (updated with reply information).

Current reply mode is determined by the ‗Manual Reply‘ parameter in the Long-Range Configuration view. When set to ‗Off‘, reply mode will be AUTO. If set to ‗On‘, reply mode will be MANUAL or EXT APPL depending on whether the replies are generated by manual inputs from the display keyboard or input through the serial interface.


Installation Manual


7000 109-153, B Page 88

7.4.3 LR input data and formats

The input data and formats are in form of two Long Range interrogation sentences - LRI and LRF, see Table 7-5.

The LRI-sentence contains the information needed to determine if a reply needs to be constructed. The LRF-sentence identifies the information items that are being requested. Details of each sentence can be found in Ref. [2].

LRF - Long Range Function

7.4.4 LR output data and formats

The output data and formats are in form of four Long Range reply sentences – LRF, LR1, LR2 and LR3, see Table 7-6.

The LRF sentence provides the ‖Function Reply Status‖ for the requested information. Following is a list of ‖Function Reply Status‖ characters with the status:

2 = Information available and provided in the following LR1, LR2 and LR3 sentences.

3 = Information not available from the AIS system.

4 = Information is available but not provided (i.e. restricted access determined by ship‘s master).

The LR1 sentence identifies the destination for the reply and contains the information items requested by the "A" function identification character in the LRF sentence.

The LR2 sentence contains the information items requested by the "B, C, E, and F" function identification characters in the LRF sentence.

The LR3 sentence contains the information items requested by the "I, O, P, U and W" function identification characters in the LRF sentence.

APPENDIX A.7 – TRANSPONDER VHF-CABLE SELECTOR

The table below gives recommendation on cables that can be used for the VHF-antenna connections. The cable attenuation shall be kept as low as possible, a 3 dB loss is the same as a reduction of the input and output signal to a half.

Ex: A cable of 40 meter RG 214 has a cable attenuation of 2.8 dB.

Type Attenuation @ 150 MHz (dB/100m)

(mm) Weight (kg/100m)

RG 214 7 10.8 18.5

RG 217 5 13.8 30.1

RG 225 8 10.9 23.3

APPENDIX A.8 – TRANSPONDER GPS-CABLE SELECTOR

The table below gives recommendation on cables that can be used for the Transponder GPS-antenna connections. Due to the high frequency it‘s important that the attenuation in the cable is low for the specific frequency (1.5 GHz).

Type Attenuation @ 1.5 GHz (dB/m)


RG 58 0.9 5 3.7

RG 400 0.6 4.95 6.3

RG 223 0.6 5.40 5.5

RG 214 0.35 10.8 18.5

RG 225 0.3 10.9 23.3

For optimum performance of the transponder approximately +10dB gain should be available when the cable attenuation has been subtracted from the GPS-antenna preamplifier gain. The net gain shall not exceed +26dB.

Example:

Cable type

Preamplifier Gain (dB)

Required min cable length (m)

Recommended max. cable length (m)

RG 58 12 0 2

RG 58 26 0 18

RG 58 30 4.5 22

RG 223 12 0 3.5

RG 223 26 0 26.5

RG 223 30 6.5 33.5

RG 214 12 0 6

RG 214 26 0 46

RG 214 30 11.5 57

Min length = (Preamp. Gain – 26 dB)/Cable attenuation per meter

Max length = (Preamp. Gain – 10 dB)/Cable attenuation per meter

APPENDIX A.9 – SENSOR ANTENNA CABLE SELECTOR

The table below gives recommendation on cables that can be used for the navigation (MGA-2 or MGL-4) antenna connection. Due to the high frequency of GPS signals it‘s important that the attenuation in the cable is low for the specific frequency (1.5 GHz).

Specification of recommended cables

Type Attenuation @ 1.5 GHz (dB/m)


RG 58 0.9 5 3.7

RG 400 0.6 4.95 6.3

RG 223 0.6 5.40 5.5

RG 214 0.35 10.8 18.5

RG 225 0.3 10.9 23.3

For optimum performance of the R4 Navigation Sensor, 12 dB should remain after subtraction of cable loss from the antenna pre-amplifier gain. Thus, a maximum of 18 dB signal loss is allowed in the antenna cable, when using the 30 dB gain MGA-2 GPS antenna or MGL-4 Combined GPS/Beacon antenna. Given this criteria, the following recommended cable maximum lengths have then been calculated.

Recommended maximum cable length using standard antenna

Cable type Max length with MGA-2 or MGL-4

RG 58 20 m

RG 400 30 m

RG 223 30 m

RG 214 51 m

RG 225 60 m

Maximum cable length is calculated as:

Maximum cable length = allowed total loss / cable attenuation per meter
