17 Product description 2.6 AIS system In accordance with IMO requirements all SOLAS ships in international traffic above 300GT shall carry an AIS mobile station. A major task for competent authorities such as coastal and harbour authorities, police, customs, military, search and rescue centres and other, is to monitor ship traffic within their territorial waters. Through an AIS infrastructure system, the governmental organisations will have the full traffic overview of all SOLAS ships, as well as AIS Class B within the AIS base station coverage area. The AIS system provides an efficient tool to increase the situation awareness, the efficiency of operations and safety. Experience shows that the workload for the operators involved in vessel tracking and monitoring, is heavily decreased. The implementation plan for SOLAS vessels started in 2002 and was finalised in A Class A AIS mobile station consists of a GPS receiver and VHF radio modules. The AIS mobile station uses GPS satellites to determine vessel position. The position data should, however, come from the ship s primary navigation system. If this is not available, the position will be provided from the internal GPS receiver. The internal GPS receiver is also used for time-synchronisation of received and transmitted data. VHF communication is used for broadcast and reception of vessel position data, navigational data, static and voyage related information with other vessels and base stations. For an AIS Class A mobile station serial line communication and the NMEA data protocol are used to exchange AIS data with other navigation systems. AIS data are displayed on the MKD unit or external systems such as ECDIS/ECS or radar. The Self-Organised Time Division Multiple Access protocol (SOTDMA) organises access for all users by operating with time-frames divided into single slots. AIS is based on SOTDMA communication on two frequencies ( MHz and MHz). Vessels will first listen in order to establish the slot table and then start sending in a vacant slot. When in normal operation, each station sends in a previously announced or randomly chosen slot. Future transmission slots will be allocated and communicated to surrounding AIS mobile stations. Hence a self-organised communication avoids transmission in same slots. The system is designed to give preference to close targets. Targets far away will drop out first in the event of overload. The length of a timeslot within the SOTDMA telegram is 26.6 milliseconds. There are maximum 2250 slots per minute on each AIS frequency, in total 4500 slots. One navigation message from a ship occupies one slot. B610-02/4.0 15

18 AIS BS610 The transmission rate of a position message (msg 1-3) depends on the speed and turn-rate of a vessel. Static information (msg 5) is sent every 6 minutes.

GPS is the only GNSS with full constellation. However, GLONASS is operable but do not have full constellation. Galileo is a third GNSS, which is in the development phase GPS - Global Positioning System The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of satellites placed into orbit by the U.S. Department of Defence. GPS was originally intended for military applications but in the 1980es the government made the system available for civilian use. GPS provides a highly accurate and continuous navigation service. It provides 24-hour, all weather and global coverage. The system is divided into the following three segments: Space segment Control segment User segment This segment consists of at least 24 satellites (21 active plus 3 operating spares) in 12-hour circular orbits. At an altitude of km, each satellite is transmitting orbital and clock parameters. This segment comprises Ground Control Stations geographically spread for monitoring, up-loading and control of the satellite transmitted characteristics. This segment comprises GPS receivers installed on board ships, aircraft etc. to track satellite signals and transform them into position, velocity and time. 16 B610-02/4.0

19 Product description Each GPS satellite transmits radio signals at two microwave frequencies in the L band, MHz (L1) and MHz (L2). The L1 signal is modulated by a precise (P) code for Precise Positioning Service (PPS) and a course/acquisition (C/A) code for Standard Positioning Service (SPS). The P code is for military and authorised personnel only and is encrypted before broadcast to GPS users. The C/A code is for civil users. Until 1 May 2000 the accuracy of the C/A code was degraded to 100 m (2DRMS) horizontal positioning by the use of Selective Availability (SA). However, SA is now switched off and the position accuracy of the system is about 16 metres 95% CEP. The fundamental technique for GPS is one-way ranging from the satellites. Triangulation, based on ranging from the satellites, is the basis of the system. In order to triangulate, the GPS measures distance using the travel time of a radio message. To measure travel time, timing is crucial. GPS therefore needs very accurate clocks. The transmission is referred to highly accurate atomic frequency standards on board the satellites, which are in synchronisation with the GPS system time base. The time difference from when the signal leaves the satellites until it is received at the GPS receiver, is measured. The distance is computed by multiplying with the speed of light. Once the distance to a satellite is known, the satellite's position in space must be found. The GPS satellites are launched into very precise orbits and their position is transmitted to the user. Knowing the satellites' position and the distance to the user receiver, the user position can be computed. Three perfect measurements can solve a three-dimensional point in space. However, the crystal clocks in the GPS receivers are drifting, and the position is therefore inaccurate. To calculate a three dimensional position, four unknowns have to be solved (latitude, longitude, height and receiver clock offset). To solve this equation with four unknowns it is necessary with range measurements from four or more satellites. The geometry, and hence the accuracy of the position calculation, varies with the number of satellites available and their location. Using differential corrections from one or more GPS Reference Stations significantly reduces all major error sources. This principle is called differential GPS (DGPS) Differential GNSS (DGNSS) Position accuracy may be enhanced by using the differential technique. This can be achieved by using either traditional DGNSS or by clock and orbit corrections Traditional DGNSS (RTCM) The DGNSS system improves the position accuracy by using the differential technique. This is accomplished by accurately surveyed GNSS reference stations which calculate pseudo-range corrections for all the satellites tracked by the reference station's GNSS receiver. The DGNSS system also uses a communication link for transmission of correction data from the Reference Station to the vessel. B610-02/4.0 17

20 AIS BS610 Each GNSS reference station compares the measured distance to a satellite with the one calculated based on the satellites' and the reference station's known co-ordinates. The resultant range difference is the correction data, which are broadcast from the GNSS reference stations to the Differential GNSS correction receiver(s) on board the vessel(s). The correction data can also be broadcast via satellite, e.g. an Inmarsat satellite. At the vessel, these pseudo-range corrections are applied to correct the pseudo-ranges received by the vessel's GNSS receiver, prior to using them for the calculation of a three-dimensional navigation solution. The concept of a differential GNSS (DGNSS) real-time system is illustrated in the figure. Figure 1 Differential GNSS (DGNSS) concept Clock and orbit corrections In contrast to having a unique set of satellite corrections specific to each reference site, the orbit and clock concept consists of one set of corrections for the satellites, which is valid globally. The orbit and clock concept uses reference stations with a worldwide spread to calculate the orbit and the clock value of each GNSS satellite more accurately than the broadcast GNSS ephemeris. Orbit and clock corrections to the broadcast GNSS ephemeris are then transmitted to the user. The correction data can be used at any location, regardless of distance to any reference station, making the system truly global. Local ionospheric errors are corrected at the user end by using a dual frequency receiver. Use of orbit and clock corrections improves the accuracy from metre level to decimetre level. 18 B610-02/4.0

21 Product description Figure 2 Orbit and clock concept SBAS system description SBAS, Satellite Based Augmentation System, is a generic term for GPS augmentation systems such as WAAS, EGNOS, MSAS and GAGAN, which use geostationary satellites to broadcast information to users over a large geographical area. SBAS shall provide additional accuracy and reliability for the GPS system. The systems are independent but based on the same principles. The systems are fully interoperable and compatible. SBAS is designed to improve the accuracy and ensure the integrity of information coming from GPS satellites. The signals from GPS satellites are received at a network of ground based reference stations. Measurements from the reference stations are routed to master stations, which generate and send the correction messages to Geostationary Earth Orbit (GEO) satellites. These GEO satellites broadcast the SBAS message to the users on the same frequency as GPS. This augmentation information consists of GPS-like ranging signals and correction information on GPS errors caused by the satellites themselves or by the ionosphere WAAS WAAS, Wide Area Augmentation System, is an American GPS based assistance to air traffic, built and operated by the FAA, Federal Aviation Administration. The FAA commissioned WAAS in July 2003 throughout the continental United States and most of Alaska. The next segment of WAAS was completed in 2008 and will expand service coverage to all of the continental United States, most of Alaska and significant regions of Canada and Mexico. B610-02/4.0 19

22 AIS BS610 Figure 3 SBAS coverage EGNOS EGNOS, European Geostationary Navigation Overlay Service, is the European SBAS and is being deployed to provide regional satellite based augmentation services to aviation, maritime and land-based users in Europe. EGNOS is a joint project of the ESA, the European Commission and Eurocontrol. EGNOS is the first activity in the field of Global Navigation Satellite Systems (GNSS) and the first step to Galileo, the full global satellite navigation system under development in Europe. EGNOS ownership was transferred to the European Commission in 2009 which also operates the service MSAS MSAS, Multifunctional transport Satellite-based Augmentation System, is a Japanese augmentation system, implemented by the Japanese Civil Aviation Bureau. MSAS was commissioned in September GAGAN GAGAN is an Indian Space Based Augmentation System. The system was developed jointly by the Airports Authority of India (AAI) and the Indian Space Research Organization (ISRO). GAGAN was operational as of Signal distribution SBAS signals are distributed by geostationary satellites. The broadcasting frequency of the signals is the same as GPS (L1, MHz). The following PRNs have been allocated to the SBAS satellites: 20 B610-02/4.0

AIS mobile stations (on board vessels), AIS AtoNs, AIS Base Stations and other AIS devices are transmitting on two standardised AIS channels; Channel A ( MHz) and Channel B ( MHz). Two power levels are used on the vessels; low (1 W) and high (12.5 W). The range, distance between transmitting unit and receiving unit, is mainly depending on antenna height and the antenna installation. Use of for example combiners will introduce a loss and hence reduce the range. It is important to install the antenna as high as possible. Theoretical range can be estimated based on the following formula, which is a line of sight estimation: D (km) = 12, 75xH (m) D = Distance (range) in kilometers. H = antenna height in metres. Note that both the transmitter and receiver side (see figure) need to be considered. This is an estimation of line of sight, and is very conservative for VHF range calculations. In order to give a better estimate of VHF range under normal metrological conditions 10 % should be added to the line of sight distance. Special metrological conditions may affect the radio range considerably. B610-02/4.0 21

The LED to the right continues to flash yellow until the AIS Unit is ready to send using RATDMA. Transmission in FATDMA starts after 3 seconds. During normal operation the LEDs have these functions. The TX LED has these functions: TX transmitting on Channel A, the LED to the left flashes green. TX transmitting on Channel B, the LED to the left flashes yellow. TX transmitting on Channel C, the LED to the left flashes red. TX is off, the LED to the left is constantly red. The RX LED has these functions: RX receiving on Channel A, the second LED to the left flashes green. RX receiving on Channel B, the second LED to the left flashes yellow. RX receiving on Channel C, the second LED to the left flashes red. The GPS LED has these functions: When the AIS Unit is tracking satellites, the second LED to the right flashes green. When the AIS Unit receives GPS data but no position or time, the second LED to the right flashes yellow. The Alarm LED has this function: When there is an alarm situation, the LED to the right is constantly red. Otherwise it is not lit. B610-02/4.0 29

32 AIS BS Internal alarm system BIIT The AIS module has a built-in alarm functionality. The alarm is generated by the Built In Integrity Test (BIIT). The software handles generated alarms. The alarm may lead to some kind of actions taken by the system. This depends on what kind of alarm that arises. The alarm generated by the BIIT may lead to stop in transmission of messages. When an alarm arises, this will be identified by a red alarm LED. There will also be generated an alarm message on the PI port SNMP Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks". A SNMP agent is installed on the AIS module in the AIS Unit trapping the BIIT alarms of the system. The Management Information Base (MIB) can be downloaded from FTP server on request. 30 B610-02/4.0

33 Installation 4 Installation This chapter covers installation of the AIS Unit and the GNSS antenna, VHF antenna and, optionally, the power amplifier. Note The AIS 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 AIS Unit, GNSS antenna, VHF antenna and, optionally, power amplifier) Installation of the AIS Unit in the cabinet Installation of the power amplifier in the cabinet (optional) Installation of coax connectors Installation of the GNSS antenna and cable Installation of the VHF antenna and cable Connection of cables between the system and external equipment System configuration 4.1 Location of system parts Antenna location for AIS systems This system is likely to be co-located with other types of radio equipment at the installation site. Therefore special precautions are required when mounting the antennas for GNSS and VHF. The figure below gives some guidelines for antenna locations. B610-02/4.0 31

34 AIS BS 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. 32 B610-02/4.0

35 Installation Figure 4 Good antenna location Figure 5 Bad antenna location, typically masking situation 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. B610-02/4.0 33

36 AIS BS610 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 minimum 2 metres horizontally and minimum 1.5 metres vertically. 34 B610-02/4.0

37 Installation During installation, comprehensive tests should be carried out for potential interference by conducting transmissions from each RF source for extended periods, individually and simultaneously GNSS antennas in hazardous locations The GNSS antenna GPS 4, manufactured by Procom, can be used in an ATEX Europe EX zone 2 location with specifications given in label example. This only applies to installation with equipment delivered by Kongsberg Seatex AS VHF antenna For the VHF antenna, consider the following: Mount the antenna in a location where free sight is ensured. Free mounting, and as high as possible is preferable, otherwise the SWR and the radiation diagram will be influenced. The higher the location, the better the coverage. Avoid mounting the antenna parallel with, and in the vicinity of, other metal parts such as masts, supporting wires etc. The antenna should be protected from direct illumination of radar beams and other transmitting antennas such as Inmarsat antennas. Run the cables in a steel pipe in areas where the danger for radiation is high AIS Unit When installing the unit, note the following: The unit is designed for indoor installation and must 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 IEC 60945/EN 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 Power amplifier Note The power amplifier is optional and not a part of the standard delivery. When installing the 100 W power amplifier, consider the following: The unit is designed for indoor installation and must not be exposed to heavy vibrations, transformers or similar. B610-02/4.0 35

38 AIS BS610 The unit is to be mounted in a 19 inch cabinet. Ensure that there is space above and below the unit due to heat transfer. All connections to the unit are on the rear side and available space for cable connections and service must be provided. 4.2 AIS Unit installation The AIS Unit is to be mounted on attachment rails in a standard 19 inch cabinet. Note The AIS 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. Procedure 1 Remove any plastic film from the unit. 2 Place the unit on rails or shelves in the 19 inch cabinet. This to ensure that the unit is supported at the rear. 3 Fasten the unit with four screws in the front. Minimum 10 cm free space is needed behind the unit for connection of cables. 4 Install the AC power cable in the power supply and to a suitable grounded power outlet. 5 The power supply chassis must be grounded to vessel ground. 4.3 Power amplifier installation The power amplifier can be used to compensate for loss between the AIS Unit and the antenna. Maximum power output is 100 W. The power amplifier can be controlled from the base station Web interface. The power amplifier is to be mounted on attachment rails in a standard 19 inch cabinet. Note The power amplifier is optional and not a part of the standard delivery. Note The power amplifier is heavy and it will produce heat. 36 B610-02/4.0

39 Installation Procedure 1 Place the unit in the cabinet with space above and below. This to ensure enough ventilation due to heat transfer. 2 Connect the DIN cable between the power amplifier and the AIS Unit. 3 Connect a coaxial cable from the VHF connector on the AIS Unit to the circulator port 1. 4 Connect a coaxial cable from the circulator port 2 to the power amplifier. 5 Connect the VHF TX cable to the power amplifier. 6 Connect the VHF RX cable to the circulator port Antenna and cable installation The maximum length for each of the antenna coaxial cables is 30 metres for RG214 and 100 metres for 1/2" Superflex. If longer cables are needed, a low noise signal amplifier (LNA) should be fitted. It is recommended to use lightning arrestors. See Lightning arrestor specifications on page GNSS antenna and cable installation The cable recommended for the GNSS antenna is ½" superflex. B610-02/4.0 37

40 AIS BS610 Caution If the antenna cable is attached to the AIS 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 can be damaged. Caution The GNSS connector is the connector located to the right seen from the rear end. Do not confuse with the VHF connector. How to install the antenna 1 Attach the interconnection pigtail cable to the antenna connector. 2 Wrap the cable connection with waterproof self-vulcanising tape. 3 Thread the interconnection cable through the extension pipe and the mounting bracket and attach the extension pipe with the mounting bracket to the antenna. 4 Attach the antenna mounting bracket to the ship's masthead or pole with the U-bolts. 5 Connect the interconnection cable to the ½" superflex cable. 6 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. 7 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 main 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. 8 Check the antenna cable for short-circuiting. 9 Connect the other end of the ½" superflex cable to the interconnection cable. This cable is delivered in order to get secure cable runs to the main unit. 10 Connect the interconnection cable to the receiving device. All GNSS receivers provide necessary power through their antenna RF connectors. Related topics GNSS antenna mechanical dimensions and installation on page VHF 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 30 metres, while a ½" superflex cable is used for distances up to 100 metres. 38 B610-02/4.0

41 Installation Caution If the antenna cable is attached to the AIS 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 AIS module can be damaged.

43 Configuration 5 Configuration 5.1 Configuration methods This system is primarily made for configuration with standardised AIS NMEA sentences. These sentences are described in the AIS Base Station test standard IEC Relevant sentences in IEC (AIS AtoN standard) are also implemented. The described configuration sentences are normally sent to an AIS Unit from a user interface (UI) installed on a server/pc and are one of the tools included in an AIS Service Management System (ASM). In order to make the user independent of a configuration UI and NMEA sentences, a WEB interface has been included in this system. IP address when delivered from factory is: LAN Subnet Gateway Configuration with NMEA sentences The AIS BS test standard IEC defines the AIS NMEA sentences. New software upgrades will be available after changes in the standard. As the NMEA (PI) sentences are standardised and available in the standard, this manual will not describe the NMEA sentences. TCP/IP port (multiclient) for configuration of the system is B610-02/4.0 41

45 Configuration Changing parameters via WEB interface The WEB interface consists of folders for the various settings, which again have sub-folders. When you click a folder, a dialog box with the settings appears. This is where you change the settings. When you have made the changes, they need to be confirmed before the changes take place. This confirmation is carried out under Review changes. Here are all the changes listed and you are asked to confirm WEB interface Help function A description on how to use the WEB interface is available when connecting to an AIS Unit. In addition there is a short description linked to all parameters that are visible when hovering over the parameter name. B610-02/4.0 43

46 AIS BS Reconfiguration of IP address via WEB interface Changes to the IP address, subnet mask, gateway and host name are located under Network Setup. As a typing error during remote configuration might lead to loss of remote access, special care should be taken during changes of network parameters. The user will be asked to apply changes and a warning will be given. The system will automatically redirect the user to the correct address after the change if the user is on the correct subnet Software update via WEB interface The software can be updated via the WEB interface. After clicking Update SW, you will be asked for a location for the new software. The system will check the validity of the update before the software is restarted and the update takes place. The software can also be updated locally via an USB stick. 44 B610-02/4.0

47 Configuration Related topics Software updates on page Message types The AIS system supports different messages on the VHF data link and on the PI and LAN interfaces. The illustration shows the message flow at VDL and PI on serial and/or LAN without the use of TSA/VDM pairs. After start up, that is the first minute after the AIS Unit software has started, the system starts to transmit message 4 every 10 seconds minimum. The transmit interval is configuration dependent. The start slot must be set for both Ch A and Ch B. The start slot for Ch B = the start slot for Ch A + 375, if the interval is set to 750 (default). The start slot is available under ECB settings VDL messages Via the VDL interface the system can receive or transmit the following messages (when using TSA/VDM pairs more messages are supported on TX): B610-02/4.0 45

In this example the BSVDM indicates that this is data received from another unit. The B indicates that the message is received on AIS channel B ALR sentence structure The structure for an ALR sentence can be as described below: B610-02/4.0 51

54 AIS BS610 $BSALR, ,3,A,V,AIS: RX channel 1 malfunction*23 The $ sign indicates that this is an ASCII text sentence where it is possible to read some of the information directly. Typical use of this sentence type is for the alarm information.

There are two types of alarm messages which consist of two different sentences. These are the TXT and the ALR sentences. The TXT indicates a change in status of some operational parameters, and the ALR informs of an error situation that might need corrective action. An error situation may arise if there is a TX or RX malfunction. The ALM LED in the front of the AIS Unit will be lit if an error situation arises. Note If Comment Blocks are enabled, then Comment Blocks are required for input sentences to the PI as well. If enabled, sentences without a Comment Block will be discarded. 5.4 Comment/tag block Under BCE there are two options of interest in relation to blocks; 52 B610-02/4.0

55 Configuration Enabling Enable blocks will enable the use of comment blocks. Enabling Use_tag_blocks will enable the use of tag blocks over comment blocks. Enable blocks must be enabled independently of which block type is wanted. The difference between comment blocks and tag blocks are what information can be represented within the block. Tag blocks have a sequence ID number that is unique to every interface (of the PI), while comment blocks use C-time increment of one second resolution to time-tag the blocks. The dictionary used for representing the parameters is different as well. See various standards for specification. 5.5 Differential corrections The system can receive RTCM 2.3 DGPS corrections on the network (TCP/IP port 4713). If message 17 is enabled, the system will start to transmit DGPS corrections embedded in message 17. Message 17 can be enabled via the web interface configuration. Click the folder BS Setup ECB Channel A or ECB Channel B. The message can also be enabled through the use of NMEA messages. 5.6 Dependent and independent mode The system is capable of supporting both the traditional Independent mode operation and the Dependent mode operation. In Independent mode the system will manage the radio link autonomously. The Dependent mode allows an external application to handle the radio link. To configure the system for Independent mode operation, one or more of the following configuration parameters must be set: RATDMA enabled DLM reservations set ECB transmission schedule set for one or more messages. By disabling all the parameters above, the system will start to operate in Dependent mode. Typical PI output in Dependent mode looks like this:!bsvdm,1,1,,a,30071l0p?w<tsf0l4q@>4?wp1ru1,0*5f!bsvdm,1,1,,a,402mbm@000htt0gwvptbwp700`gv,0*22!bsvdm,1,1,,b,13nbpj0p010gbe:tcc`u`gwd0<0j,0*00!bsvdm,1,1,,b,13mhpp00000gw1htc>3p01m@08hk,0*2f!bsvdm,1,1,,a, iv?uiawft=jnmqicpgvo?vbm3lac>pnkbe@,4*0d!bsvdm,1,1,,b,30071l0p?w<tsf0l4q@>4?wp1rpa,0*29!bsvdm,1,1,,b,402mbm@000htt0gwvptbwp700`mm,0*30!bsvdm,1,1,,a,30071l0p?w<tsf0l4q@>4?wp1p01,0*18!bsvdm,1,1,,a,402mbm@000htt0gwvptbwp700uat,0*33 B610-02/4.0 53

56 AIS 5.7 Redundant Base Stations A redundant Base Station installation consists of two equivalent Base Station units. The units are connected via a serial cable (0-modem cable). This system has a dedicated Redundancy port at the rear (RS-232). Redundant Base Stations can operate in various modes Base Station operation modes Standalone with TX ON The serial communication between the units has failed. Both units will immediately enter the Standalone mode and the last active unit will continue transmission of VDL messages. Missing reception of message 4 will enforce a "switchover" but dependent on configuration, loss of more than one message 4 is accepted. As long as one of the units receives message 4 from the other unit, the redundancy is enabled but reduced Standalone with TX OFF at one unit The redundancy is disabled and the unit with TX ON will continue transmission of VDL message. The unit with TX OFF will be in Maintenance mode Hot standby The redundancy is enabled and this is the inferior unit with no transmission of VDL messages. The other unit is active Active The redundancy is enabled and this is the superior unit with transmission of VDL messages. The other unit is hot standby. If the active Base Station or associated services fails, or suffer from severe malfunction, a switchover will take place and the hot standby unit will take over and operate as the active AIS Base Station. For maintenance purposes it is possible to turn off the redundancy, i.e. set the TX OFF. TX OFF can be configured with an NMEA sentence or via the WEB interface. 54 B610-02/4.0

57 Configuration Redundancy configuration In the WEB interface BS Setup Redundancy there are some parameters related to the redundant operations. The Enabled parameter must be manually set to enable or disable the redundancy. The following parameters are available (default values are shown): [SECTION: REDUNDANCY] ENABLED 1! Enable redundant operation! 0 = Disable redundant operation, standalone! 1 = Enable redundant operation 0! Operational Unit (must be 0) OPER_MODE! Operational Mode! 0 = Hot Standby! 1 = Active! 2 = Standalone COM N 8 1! Port definition (must not be changed) HOTSTBY_VDM_OUTPUT 01! VDM output by hot standby unit! 0 = Disable output! 1 = Enable output 0! Active time for unit (internal use) PI_INFO_INTERVAL 10! Output of Info sentences on PI / LAN! 0 = Off B610-02/4.0 55

58 AIS BS610! Time in sec VSWR_ALR_SWITCHOVER_TIME 1! Time to switchover if SWR alarm detected! 0 = No switchover, else X seconds Startup Active or Hot standby To be able to operate in Redundant mode, it is required that the units have equal MMSI numbers and that transmission of VDL messages are not turned off (TX OFF). For these conditions the Standalone mode is always entered. If no corresponding Base Station connected for redundancy operation is detected, the Standalone mode will be entered. When a corresponding Base Station connected for redundancy is started and detected by the already running unit, this standalone unit will be active. The last started unit will become hot standby regardless of the mode defined in the setup file (OPER_MODE). If the units are started at the same time and have equal mode, the unit with the highest MAC address has precedence to be active. The unique identifier should be unique for every Base Station in a redundant configuration. This will allow interaction with each Base Station without knowing from where a specific NMEA sentence originates (for NMEA sentences without UID, the comment block can be enabled to achieve this). 5.8 Output of GPS sentence on PI In the WEB interface Setup folder Misc there is a parameter related to output of GPS sentences on PI. It is default set to 0. If changed to 1 and acknowledged under Review changes, the GSV sentence will be output on PI. 1 Access the WEB interface for configuration. 2 Click the Setup folder Misc. 3 Change the SATELLITE_MON_INTERVAL parameter to 1. 4 Confirm the change under Review changes. 56 B610-02/4.0

59 Getting started 6 Getting started This chapter describes the main operating procedures for getting started and using the AIS Unit. 6.1 How to turn on the AIS Unit 1 Ensure that the power cable, the serial connection(s), the network and the antennas are connected. 2 Push the lid to the left on the AIS Unit to reveal the ON switch. 3 Press the ON switch. 4 After an initialisation period, the GPS LED will start to blink. The initialisation may take up to 15 minutes, depending on the GPS almanac. Related topics LED indicators AIS Unit on page AIS Unit settings The following settings must be carried out in order to get a working AIS Unit. We recommend to carry out these settings via the WEB interface. Refer to Configuration on page 41 for other settings. The AIS Unit is by default configured Network settings How to change the network settings 1 Connect the network port ( AIS LAN) of the AIS Unit to a PC, network switch or hub. The unit is delivered with default IP address. 2 Type the address: ip-address of AIS LAN> to connect to the WEB interface of the AIS module for configuration. Default IP address is: Or you can use NMEA sentences for configuration of the AIS module. B610-02/4.0 57

60 AIS BS610 4 Open Network setup on the Web interface to change the IP settings of the AIS module. 5 Default PI TCP port on AIS LAN is Output on TCP port 4712 (Full_PI_TCP) can be turned off under the folder Setup MISC. The port number can be changed under the Setup folder Network LAN_PITCP_PORT. Use port numbers above Open Setup Network to change the PI UDP settings. Change the settings to be in accordance with the general AIS network settings. The PI UDP port can be turned OFF by entering 0 in the LAN_BRC_PORT under the Setup folder Network MMSI Default MMSI when delivered is The MMSI needs to be changed after startup. Set the seven-digit MMSI number, either by sending a BCF sentence to the AIS Unit or via the WEB interface. The AIS Unit will automatically add two zeros at the front to fulfil the mandatory nine digits Unique identifier Set the unique identifier (UID) according to the description in IEC Either by sending a SID sentence to the AIS Unit. If the UID is not set, the default factory set UID will be used. This can be queried by the VER sentence. The UID can also be set in the WEB interface Position source Set the position source that shall be used. Internal GPS is by default enabled. Normally the user will change to surveyed position. The position can be set by sending a BCF sentence to the AIS Unit. The position can also be set in the WEB interface Radio VHF channels and power Default VHF RX and TX channels are the standard AIS channels. Ch C is default off. Power level is default 12 W. Parameters can be set by sending a BCF sentence to the AIS Unit. These parameters can also be set in the WEB interface under Setup Radio. Under Setup Radio there is a channel C available in addition to the traditional Ch A and B. Channel C can be used for DSC or TDMA. Originally it was meant for DSC, but as the need for DSC disappeared, a TDMA option has been implemented. Hence another frequency in the maritime band can be configured. Typically use of Ch C could be for secure /military AIS traffic. Use the Help function to configure the modulation. Power can be selected for the Ch C separately in the same view Reporting rates Default factory setting for the AIS Unit is message 4 start slot Ch A = 10 and Ch B = 385, message 4 used = B610-02/4.0

61 Getting started All slot allocations and reporting rates should be set by an authorised authority. Reporting rates are set by sending an ECB sentence to the AIS Unit or they can be set in the WEB interface AtoN Setup. Set the Message 4 Start Slot in BS setup under ECB. A value of 1 indicates no transmission of message 4. Set a value between 0 and 374 to make the AIS Unit transmit Message 4. The other messages (17, 20 and 22) can be turned off. To enable the transmission of messages other than message 4, the AIS Unit needs to be told the slot reservations (DLM sentence). If the ECB is used to enable a scheduled message (other than message 4) and there is no slot reservation for this message, the message will not be sent. Slot reservations and transmission schedule must match. 6.3 Status information The Status page in the WEB interface holds information on Alarms (if any), Status and Station List. Alarms, if any, are listed in addition to own position (internal GNSS pos). The Station List gives the number of visible AIS vessels and the distance to the most distant unit. Forwarded and reflected power are presented in the Status box. Reflected power should be between 10 % and 20 % of the forwarded power. The reflected power will be presented after the first transmission. The serial number of the AIS Unit and the AIS module is available under the Update SW page. If the serial number of BS610 is -1, the AIS Unit has been produced before the support for serial number was implemented ( ). B610-02/4.0 59

62 AIS BS Advanced configuration All configuration of the AIS Unit, specifically slot allocations and reporting rates, should be carried out by a competent authority. Certain parameters need to be set in order for the unit to be able to send data on LAN to the correct network. IP_ADDR SUBNET_MASK GATEWAY LAN_BRC_ADDRESS LAN_BRC_PORT LAN_BRC_ADR_CLI(ents) Send the following sentences to configure the unit: SID Installation of Station identification (UID, MMSI) BCF Configuration (MMSI, position, VHF settings, etc.) BCE Gen. config. extended (RATDMA, UTC source, etc.) CAB Transmission on channel A/B, restart SPO Select device s reception processing and output DLM Data link management (FATDMA allocations) ECB Configuration broadcast rates for messages (4, 17, 20, 22, 23) ACA Region channel management AGA Preparation of a group assignment message (23) ECB is used to set up the transmission schedule of the various messages. The position report is VDL message 4 and when configured it will have a reporting interval of minimum 10 seconds. Furthermore, the AIS RTCM message 17 can be configured for transmission on the two channels separately. To inform other AIS units within radio range of the fact that this Base Station is using specific time slots for transmission, the VDL message 20 must be configured for transmission. This can also be done for two channels separately. If the coverage area of the Base Station is using non-standard AIS radio parameters, then message 22 should be scheduled for transmission. If a group assignment message shall be broadcasted, then message 23 should be scheduled for transmission. All of this is done by sending the ECB message. Note Prior to sending the ECB sentence, the DLM sentence must be used to allocated FATDMA slots for the scheduled messages (DLM sentence is not necessary for message 4, but is recommended). Radio channels can be turned ON or OFF at authorities discretion. Radio channel control and the possibility to reboot the AIS Unit can be done by sending the CAB message on the PI. 60 B610-02/4.0

63 Getting started 6.5 Channel management The NMEA messages ACM and ACA are used for channel management. ACA sets the area and radio parameters for the area where non-standard AIS radio parameters apply. An authorised operator can perform this task. Sending an ACA message will cause the AIS Unit to alter its own radio parameters. ACM is used to make the AIS Unit transmit a channel management message 22 to a designated AIS target. The message contains non-standard AIS radio parameters, but not a region. The AIS Unit can manage up to 10 different regions. These regions may be overlapping. It is not possible to configure the AIS Unit to use regions with different radio settings. All regions must have the same radio parameters. 6.6 Radio traffic management Sometimes it is necessary to limit the amount of radio traffic within a certain area, for example a port with many vessels. One way of doing this is to use the VDL message 16 and set the destined mobile station into Assigned mode. The AIS Unit will be told in which time slots it should send, and on which channel(s). An ASN message (NMEA sentence) must be sent to the AIS Unit to make it force other mobile stations to go into Assigned mode. B610-02/4.0 61

92 AIS BS610 Appendix H AIS Unit 24 V DC option This appendix gives a description of the deviation between a standard AIS Unit and the 24 V DC option. H.1 General information The 24 V DC option has part number B610-01_24VDC. A 24 V DC version of the AIS Unit is marked at the rear side with the following label. It contains a 24 V DC to 12 V DC power supply in addition to the standard 110 to 240 V AC supply. It can have both or one of the sources connected. The 24 V DC connection has no power switch. The 110 V AC to 240 V AC power switch is located under the front lid as for the standard AIS Unit. Which source is connected will be indicated by the green LEDs at the rear side. When both sources are connected, the two LEDs are lit. In this case the AIS modules are fed from both sources at the same time. If one is disconnected or the source fails, the AIS Unit will still be working. Seen from the rear side the left LED indicates status on DC and the right LED indicates status on AC source. Green means it is connected. H.2 Pinning of the 24 V DC connector The AIS Unit is delivered with a connector (female) for the 24 V DC input source. Part number is B Pin # 1 + G Input 90 B610-02/4.0
