Introduction Page 92Introduction2.1 About AISThe marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived from the Global Positioning System (GPS) and communication between vessels is by Very High Frequency (VHF) digital transmissions. There are a number of types of AIS device as follows:●Class A transceivers. These are designed to be fitted to commercial vessels such as cargo ships and large passenger vessels. Class A transceivers transmit at a higher VHF signal power than class B transceivers and therefore can be received by more distant vessels, and also transmit more frequently. Class A transceivers are mandatory on all vessels over 300 gross tonnes on international voyages and certain types of passenger vessels under the SOLAS mandate. ●Inland AIS stations. Similar to class A transceivers with additional features for use on Inland waterways. ●Class B transceivers. Similar to Class A transceivers in many ways, but are normally lower cost due to the less stringent performance requirements. Class B transceivers transmit at a lower power and at a lower reporting rate than Class A transceivers. ●AIS base stations. AIS base stations are used by Vessel Traffic Systems to monitor and control the transmissions of AIS transceivers. ●Aids to Navigation (AtoN) transceivers. AtoNs are transceivers mounted on buoys or other hazards to shipping which transmit details of their location to the surrounding vessels. ●AIS receivers. AIS receivers receive transmissions from Class A transceivers, Class B transceivers, AtoNs and AIS base stations but do not transmit any information about the vessel on which they are installed. The AIS950 transceiver is a combined Class A transceiver.Figure 1 The AIS network
IntroductionPage 102.2 Static and dynamic vessel dataInformation transmitted by an AIS transceiver is in two categories: static and dynamic data.The vessel's dynamic data which includes location, speed over ground (SOG) and course over ground (COG) is calculated automatically using the internal GPS receiver. Static data is information about the vessel which must be programmed into the AIS transceiver. This includes:●Maritime Mobile Service Identity (MMSI)●Vessel name●Vessel call sign (if available)●Vessel type●Vessel dimensions2.3 AIS operation licensingIn most countries the operation of an AIS transceiver is included under the vessel's marine VHF licence provisions. The vessel on to which the AIS transceiver is to be installed must therefore possess a current VHF radiotelephone licence which lists the AIS system, vessel Call Sign and MMSI number. Please contact the relevant authority in your country for further information regarding ship’s radio licensing requirements.

Please refer to section 4.4.2 for guidance.Figure 34 AIS transceiver dimensionsFigure 35 Mounting the AIS transceiver105 mm85 mm195 mm172 mm112 mm157 mm
Installation Page 35Figure 36 Panel mounting the AIS transceiver4.3.2 Step 2 - Installing the junction boxThe AIS transceiver receives data from the ship’s sensors via the 50 way data cable which connects to the rear of the transceiver. The other end of this cable is connected to the junction box which provides a convenient screw terminal system for connection of ships sensor data cables. Please note the following guidelines when selecting a location for the AIS junction box:●There should be adequate space around the junction box for routing of cables. See Figure 37 for details of the junction box dimensions. ●The ambient temperature around the junction box should be maintained between -15°C and +55° (5°F to 131°F).●The junction box should not be located in a flammable or hazardous atmosphere such as in an engine room or near to fuel tanks. ●The junction box must be installed in a 'below decks' environment protected from the weather.●The transceiver is supplied with four self tapping screws for attachment of the junction box to a suitable surface. Please refer to Figure 38 for guidance. ●The junction box must be located within 1m (3.2ft) of the AIS transceiver to allow for the length of the supplied data interface cable.To meet IMO requirements the AIS transceiver must be able to transmit at least Speed over Ground (SOG), Course over Ground (COG) and Rate of Turn (ROT) information. This data is obtained by connecting data outputs from the ship’s DGPS, Gyrocompass and other sensors to the transceiver via the junction box.
InstallationPage 36Figure 37 Junction box dimensionsFigure 38 Mounting the junction box4.3.3 Installing the GPS antennaThe AIS950 AIS transceiver includes an internal GPS receiver for time synchronisation. An independent GPS antenna is required for this receiver in addition to any GPS equipment already installed on board.For mounting of the GPS antenna supplied with your AIS transceiver you will require a one inch 14 TPI pole mount. Contact your dealer to source a mount suitable for the installation location. Please note the following guidelines when selecting a location for the GPS antenna:●The GPS antenna mount should be secured to a rigid surface.●The GPS antenna should be located where it has a clear, unobstructed view of the sky overhead.●The GPS antenna should be mounted as high as possible, however it is not recommend the antenna is mounted on a top of a high mast where the motion of the vessel will cause the antenna to swing and potentially reduce the accuracy of the GPS position. See Figure 39 for guidance.178 mm52 mm76 mm165 mm58 mm
Installation Page 37●If possible mount the antenna at least 5m (16ft) from any RADAR or Satellite communications antennas, and ensure the GPS antenna is not in the beam path from any RADAR antenna.●Route the GPS antenna cable through the pole mount and then to the AIS transceiver. If extension cables are required all junctions should be made using appropriate co-axial connectors and made watertight.●Connect the GPS antenna cable to the GPS connector on the AIS transceiver as shown in Figure 40.Figure 39 GPS antenna locationFigure 40 GPS antenna connection4.3.4 Installing the VHF antennaThe AIS950 AIS transceiver requires a dedicated VHF antenna for communications. A standard marine VHF antenna is suitable. GPS antenna should be at least 5m (16ft) from RADAR or Satellite communicationantennasAway from RADARbeam pathGPS antenna mountedon a rigid surfaceGPS antenna connection
InstallationPage 38Please note the following guidelines when selecting and locating the AIS VHF antenna:●The VHF antenna should be located as high as possible and positioned as far from other antennas as possible.●The VHF antenna should have omnidirectional vertical polarization.●Where possible the VHF antenna should be installed at least 3m (10ft) away from other transmitting radio, satellite and RADAR antennas.●Ideally 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 2m vertical separation. If it is located on the same horizontal level as other antennas, the distance apart should be at least 10m. Refer to Figure 41 for further guidance.●The VHF antenna cable should be kept as short as possible to minimise signal loss. High quality, low loss coaxial cable appropriate to the installation location should be used. ●The VHF antenna cable should be terminated in a PL-259 co-axial connector for connection to the AIS transceiver.●Any outdoor installed connectors in the antenna cables should be waterproof by design.●Antenna cables should be installed in separate signal cable channels at least 10cm (4ins) away from power supply cables. Crossing of cables should be done at right angles and sharp bends in the antenna cables should be avoided.●Connect the VHF antenna cable to the VHF connector on the AIS transceiver as shown in Figure 42.Figure 41 VHF antenna installationPositioned at least 3m (10ft)from other transitting radio, satellite and RADAR antennasVHF antenna

InstallationPage 404.4.3 Sensor configurationThe AIS950 transceiver has seven NMEA0183 (IEC61162-1/2) data ports for connection of ship’s sensors and display equipment as described in Table 3. There are three input ports for ship’s sensor data and three bidirectional ports for connection of display equipment such as Radar or electronic chart displays. It is recommended that an AIS compatible electronic charting system is connected to the AIS950 transceiver for display of AIS targets. To comply with IMO regulations the AIS must be connected to speed over ground (SOG), course over ground (COG), heading, rate of turn (ROT) and position information sources. The three sensor ports are input only data ports for the connection of data from ships sensors. The four remaining ports are bi-directional high speed connections supporting data input and output from the AIS. These ports are suitable for connection to ECDIS, AIS enabled RADAR displays and Pilot equipment.All data input connections are optically isolated.Table 3 Serial data portsAll sensor ports can be configured via the sensor configuration menu which can be found under the Main menu>Installation>Sensor configuration menu option. The sensor configuration menu also includes the ability to disable the requirement for external GPS sensors to provide a DTM (Datum) sentence, as not all external GPS devices provide this sentence. 4.4.4 Junction box connectionsThe junction box provides screw terminal connections for each of the seven data ports. The connections and functions of each connection are defined in Table 4. All connections are labeled on the junction box PCB for clarity. A diagram showing connections available inside the junction box is provided in Figure 44.Use of shielded cable is recommended when connecting ships sensors and display systems to the junction box Connect the cable shield to the terminal block marked ‘shields’ in the junction box. It is possible to remove the PCB from the junction box enclosure to aid connection of cables to the screw terminals during installation.Data port Function Type Default Baud rate1Sensor 1 input (DGPS - COG/SOG/LAT/LON)Receive only 48002Sensor 2 input(Rate of Turn)Receive only 48003Sensor 3 input(Gyro heading)Receive only 48004External display / ECDIS Bi-directional 384005Pilot port Bi-directional 384006Long Range Bi-directional 384007DGPS beacon receiver Bi-directional 4800If an external GPS device which does not provide a DTM sentence is connected to the transceiver and the transceiver is configured to require DTM sentences, the external GPS data will not be accepted by the transceiver. If no DTM sentence is required the WGS84 datum will be used as a coordinate origin and the external GPS device must be configured to output position using this datum.Do not connect the shield of both the external equipment and the junction box. Connect at only one end.

Technical reference Page 576.4 Bi-directional data portsThe input circuitry of the bi-directional data ports is identical to the input circuitry for the sensor data input ports described in the preceding section. The output circuitry consists of a differential line driver IC (Texas Instruments AM26LV31E) and is shown in Figure 54.Figure 54 Data output port schematic6.5 Output drive capability of bi-directional portsBi-directional ports can supply an output current of up to 30mA. The output voltages are 0 (low) and 3.3V (high). Effective load resistance should be in excess of 100 Ohms. 6.6 DGPS portThe DPGS correction port is intended for connection to a DGPS beacon receiver. The port has the same physical characteristics as the bi-directional data ports as described in the preceding sections. If connection of a beacon receiver is not required this port can be re-configured as an additional bi-directional port to IEC61162-2. See section 3.16 for port configuration options.6.7 RS232 portThe RS232 port carries IEC61162 data via RS232 and is intended for connection to a PC during installation and service. The port can also be used to connect to PC based charting applications for display of AIS data.6.8 Input data sentence formatsAll data input is via IEC61162 / NMEA 0183 sentences. The sentences used by the AIS transceiver are documented in the subsequent sections. The sentence structure tables describe each field in the sentence starting from the left most field (field 1) after the sentence identifier. All sentences are terminated with the IEC61162 checksum shown as ‘*hh’.

Given that a GNSS receiver is tracking enough satellites to perform integrity checks of the positioning quality of the position solution, a message is needed to report the output of this process to other systems to advise the system user. With the RAIM in the GNSS receiver, the receiver can isolate faults to individual satellites and not use them in its position and velocity calculations. Also, the GNSS receiver can still track the satellite and easily judge when it is back within tolerance. This sentence shall be used for reporting this RAIM information. To perform this integrity function, the GPS receiver must have at least two observables in addition to the minimum required for navigation. Normally these observables take the form of additional redundant satellites. $--DTM,ccc,a,x.x,a,x.x,a, x.x,ccc*hh<CR><LF> Field numberDescription1ccc = Local datum 2a = Local datum subdivision code - NOT USED3x.x, a = Lat offset, min, N/S - NOT USED5x.x,a = Longitude offset, min, E/W - NOT USED7x.x = Altitude offset, (meter) - NOT USED8ccc = Reference datum $--GBS, hhmmss.ss, x.x, x.x, x.x, xx, x.x, x.x, x.x *hh <CR><LF> Field numberDescription1hhmmss.ss UTC time of the GGA or GNS fix associated with this sentence 2x.x Expected error in latitude 3x.x Expected error in longitude 4x.x Expected error in altitude - NOT USED5 xx ID number of most likely failed satellite - NOT USED
