1 General Introduction
1.1 Description of AIS
What does the abbreviation AIS stand for? AIS stands for: "Automatic Identification System" What is AIS? According to IALA regulations, AIS is defined as follows: Very simply, the AIS is a broadcast Transponder system, operating in the VHF maritime mobile Band. It is capable of sending ship information such as identification, position course, speed and more, to other ships and to shore. It can handle multiple reports at rapid update rates and uses Self-Organizing Time Division Multiple Access (SOTDMA) technology to meet these high broadcast rates and ensure reliable and robust ship to ship operation. What are the performance standards of AIS? The IMO defines the performance standards as follows: Ship to Ship working Ship to Shore working, including Long Range Application Automatic and continuous operation Provision of information messaging Utilization of maritime VHF channels
Which modules make up an AIS-Transponder? The Modules: DGPS / GPS receiver VHF Radio Antenna Computer (CPU) Power Supply
Appropriate application software connects the individual modules. In which modes does AIS function? AIS is required to function flawlessly in a variety of modes. The relevant regulations require: The system shall be capable of - An "autonomous and continuous" mode for operation in all areas. This mode shall be capable of being switched to/from one of the following alternate modes by a competent authority; - An "assigned" mode for operation in an area subject to a competent authority responsible for traffic monitoring such that the data transmission interval and/or time slots may be set remotely by that authority; - A "polling or controlled" mode, where the data transfer occurs in response to interrogation from a ship or competent authority.

1.2 AIS in an Operational Environment
This illustration depicts a typical AIS System, where two or more AIS equipped vessels (and shore based systems) are automatically communicating with each other.
On the bottom, a typical GlobalWatchTM UAIS installation in a common environment is shown. The GlobalWatchTM UAIS is connected to the vessels emergency power supply, and in connection with the VHF, and GPS-Antennas, the minimal requirements for Transponder operation are fulfilled. Both vessels in the above illustration are equipped with a GlobalWatchTM UAIS (or any other certified AIS-Transponder). Due to "Time Synchronization" they use the same organization of free and allocated windows (Slots) in the shared VHF Data Link (this method is called "Self Organized Time Division Multiple Access") to send and receive messages. Without the necessity of any active interaction, both vessels know exactly who or what is cruising nearby and where the individual object is heading.

3.5 Sensor notes
External Sensor The AIS has interfaces (configurable as IEC 61162-1 or 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 System.*1. The sensor information transmitted by AIS should be the same information being used for navigation of the ship. Interfacing problems might occur if the existing on board sensors do not have serial (IEC 61162) outputs. A converter is needed to translate the non conform data to IEC 61162 sensor data. For Example Raytheon Nav Data Repeater 133-812 *1) The fact that AIS is fitted on board a vessel does NOT entail the need to install additional sensors
other that those stated in the carriage requirements.
External GPS GNSS position sensors normally have IEC 61162 outputs suitable for direct AIS interfacing. However, it is important to note that: · The Geodetic Datum of the position data is transmitted by the sensor in WGS84 so that an IEC 61162 DTM sentence is configured. · AIS is able to process two reference points for it's antenna position, one for external, and one for an internal sensor. If more than one external reference point is used, the appropriate information needs to be input to the AIS, so that the reference point information is suitably adjusted. External Heading A gyrocompass providing heading information is a mandatory sensor input to the AIS. A converter unit (synchro or step-signal converter to NMEA 0183 v.3.0 for example Raytheon converter type: 133-812) will be needed for AIS connection in the case that the ship's gyrocompass does not provide IEC 61162 output. External Speed and Course If a bottom track (BT)-log for speed over the ground (SOG) is available, it may be connected. A converter (for example Raytheon converter type: 133-812) is needed if the BT-log does not provide IEC 61162 outputs External Rate of Turn Not all ships will 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 should be connected to the AIS. If ROT information is not available from a ROT indicator, it may (optionally) be derived from heading information through: · The gyrocompass itself, · An external converter unit (see Heading), · The AIS itself (calculated ROT).

3.6.1 Signal state definitions
The idle, marking, logical 1, OFF or stop bit state is defined by a negative voltage on line A with respect to line B, as in IEC 61162-1. The active, spacing, logical 0, ON or start bit state is defined by a positive voltage on line A with respect to line B, as in IEC 61162-1.
3.6.2
Talker drive circuits
The drive circuit meets the requirements of ITU-T V.11. The maximum output current is Imax = 50mA on each port.
3.6.3
Listener receive circuits
Multiple listeners may be connected to a single talker. The listener's receive circuit complies with ITU-T V.11. Optional termination resistors (120Ohm) for the Input-lines are provided in the Connection Box. The input terminals A, B and C are electrically isolated from the remaining electronics of the listening device. The input impedance is 30kOhm between A and B lines without the termination resistors. The minimum input voltage is ±0,3V. 3.6.4 Electrical isolation
Within a listener there are no direct electrical connection between the signal lines A and B, the signal ground C or the shield to ship's mains ground or power line. This isolation is in accordance with IEC 60945. 3.6.5 Maximum voltage on the bus
The maximum applied voltage between signal lines A and B and between either line and ground C is in accordance with ITU-T V.11. For protection against miswiring and for unintended connection to earlier TALKER designs, all receive circuit devices are capable of withstanding 15 V between both lines and signal ground for an indefinite period. 3.6.6 Data transmission
Data is transmitted in serial asynchronous form in accordance with 1.2. The first bit is a start bit and is followed by data bits, least-significant-bit first. The following parameters are used: baud rate 38 400 (bits/s) resp. 4 800 (bits/s) data bits 8 (D7 = 0), parity none; stop bits 1.

Interference to the Ship's VHF Radiotelephone The AIS ship borne equipment, like any other ship borne 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 20 seconds) soft clicking sound on the ship's radiotelephone. This affect may become more noticeable if 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). Attention should be paid to the location and installation of the various antennas, in order to support the antenna characteristics in the best possible way. VHF Antenna Installation 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 caused by obstructions such as masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize interference effects. To minimise interference effects, the following guidelines apply: · · The AIS VHF antenna should have omni directional vertical polarisation providing 3 to 5 dB gain. The AIS VHF antenna should be placed in an elevated position, as free standing as possible, with a minimum of 2 metres in horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large vertical obstruction. The AIS VHF antenna should have a visible sky of 360°. The AIS VHF antenna should be installed at least 3 meters away from interfering highpower energy sources such as radar and other transmitting radio antennas, and out of the way of the transmitting beam. There should not be more than one antenna on each level. The AIS VHF antenna should be mounted directly above or below the ship's primary VHF radiotelephone antenna, with no horizontal separation and a minimum of 2 metres vertical separation. If it is located on the same level as other antennas, the distance apart should measure at least 10 metres. See also sample for antenna layout in Appendix 9.2 (Drawings and Approvals)

Cabling The cable should be kept as short as possible to minimise attenuation of the signal. Double shielded coaxial cables equal to or better than RG214 are recommended. RG214 at VHF attenuation per meter of app. 0,07 dB/m (45m = 3,15db) VHF AIS frequency app. 162MHz

All outdoor connectors on the coaxial cables should be fitted with preventive isolation, such as shrink-stocking with silicone to protect the antenna cable against water penetration. Coaxial cables should be installed in separate signal cable channels/tubes, and at least 10 cm away from any power supply cables. Crossing of cables should take place at right angles (90°). Coaxial cables should not be exposed to sharp bends, which may lead to changes to the characteristic impedance of the cable. The minimum bend radius should be 5 times the cables outside diameter. Grounding Coaxial down-leads must be used for all receiving antennas, and the coaxial screen should be connected to the ground at one end. GNSS Antenna installation A Class A AIS must be connected to a GNSS antenna. Location The GNSS antenna must be installed where it has a clear view of the sky, so that it accesses the horizon freely through 360°, with a vertical observation of 5 to 90 degrees above the horizon. Small diameter obstructions, such as masts and booms, do not seriously impair signal reception, but such objects must not eclipse more than a few degrees of any given bearing. The antenna must be located at least three meters away from, and out of the transmitting beam of high-power transmitters (S-Band Radar and/or Inmarsat systems). This includes the ship's own AIS VHF antenna, if it is designed and installed separately. See also sample for antenna layout in Appendix 9.2 (Drawings and Approvals)
If a DGNSS system is included or connected to the AIS system, the installation of the antenna should be undertaken in accordance with IEC 61108-4, Edition 1. Cabling To achieve optimum performance, the gain of the antenna pre-amplifier should match the cable attenuation. The resulting installation gain (pre-amplifier gain - cable attenuation) should be within 0 to 10 dB. RG214 at GPS attenuation per meter of app. 0,35 dB/m (45m = 15,75dB) GPS frequency app. 1,2GHz The coaxial cable between the antenna and the AIS ship borne station connector should be routed directly, in order to reduce electromagnetic interference. The cable should not be installed close to high-power lines, such as radar or radio-transmitter lines, or near the AIS VHF antenna cable. A space of one meter or more is recommended in order to avoid degradation due to RF-coupling. Crossing of antenna cables should take place at 90 degrees, to minimise magnetic field coupling.

Antenna Layout The position of the VHF und GNSS antennas must be added to the existing antenna layout of the vessel. Power Supply The GlobalWatchTM UAIS must be supplied from the emergency power source. A further requirement is to connect AIS to the reserve power source of the GMDSS. A new battery capacity calculation must then be undertaken. See sample in 9.1 (Samples for battery calculation) Following documents are needed for the installation approval of the classification · Antenna Layout (arrangement) · Battery Calculation · Connection / Block Diagram with locations · Type Approval Certificate

4 Starting the GlobalWatchTM UAIS
After completing the hardware, antennas and external equipment installation, the initial system start-up can commence. To start the system, connect the GlobalWatchTM UAIS with the power supply. The next step is to enter the configuration like password and the MMSI number.
4.1 Service and User Passwords:
The Transponder system is equipped with two separate Passwords. 1) The User Password, which is the lower security level allows access to all menus except Menu 6: Service Configuration - please refer to the User Manual for further details on password protection. 2) The Service Password is required in order to enter the Service Configuration Menu. This is a higher security level than can be accessed with the User Password and therefore ensures that the Service Configuration is protected, and limited to authorized service personnel. The master of the vessel has to ensure that only authorised persons are allowed to make changes to the Service Configuration and ensures that the newly reset password is stored very carefully, as it can not be reset from the default "NAUT" a second time. A master key is not available. Changing the Service Password Select "Service Configuration" from the Main Menu with the cursor button [Up] & [Down] or press Nr. 6 on the keyboard.
