Universal AIS Transponder
What is AIS?
The Automatic Identification System (UAIS or AIS) is a shipboard broadcast transponder system in which ships continually transmit their ID, position, course, speed over ground, static data and voyage related data to all other ships and shore side authorities on common VHF radio channels.
The Automatic Identification System (UAIS or AIS) will be a further step to more safety on board all vessels and for vessel traffic around the world.
The new SOLAS convention Chapter V, Regulation 19, adds a requirement for carriage of automatic identification system capable of providing information about the ship to other ships and to coastal authorities automatically.
The Automatic Identification System is required for certain ship types from July 1st, 2002.
The following ships will be required to carry AIS:
- Constructed after the July 1st, 2002 – all new passenger ships and new cargo ships above 300 gt
- Until July 1st, 2003 – all passenger ships and tankers on international voyage
- Until July 1st, 2004 – all cargo ships above 50,000 gt on international voyage
The modification of SOLAS Chapter V contains a new timetable for refitting of AIS:
- Ships, other than passenger ships and tankers, of 300 gt and upwards, but less than 50,000 gt, will be required to fit AIS not later than the first safety equipment survey after July 1st, 2004 or by December 31st 2004, whichever occurs earlier. Ships fitted with AIS shall maintain AIS in operation at all times except where International agreements, rules or standards provide for the protection of navigational information.
AIS is designed to operate in one of the following modes:
- In a ship-to-ship mode for collision avoidance
- As a means for coastal stations to obtain information about a ship and it cargo
- Generation of AIS Long Range reply over INMARSAT C
- As a traffic management tool when integrated with a Vessel Traffic System (VTS)
The complete AIS includes:
- AIS Compact Display/Transponder Unit
- One VHF transmitter
- Two multi-channel VHF receiver
- One channel 70 VHF receiver for channel management
- Interface to heading and GNSS receiver and to other shipborn sensors, like RoT, Gyro
- Interfaces ECDIS/ECS
- Interfaces ARPA-Radar (Automatic Radar Plotting Aid) for retrofit, depending on the radar input possibilities
- Keyboard to input and retrieve data. The presentation is also possible on ECDIS/ECS (Option)
- GPS antenna (12 channels) for timing purposes and position redundancy
- VHF whip antenna
- Junction box with cable and plug for easy installation
- 2 x 40 m antenna cable
- Antenna adapter and all needed plugs
- Pilot plug with 3 m cable tail for interfacing pilots portable equipment (Option)
- Gyro Interface to converts all synchro or step heading signals into NMEA 0183 standard HDT (Option)

Note:
(f) For radio frequency devices subject to verification and sold solely to business, commercial, industrial, scientific, and medical users (excluding products sold to other parties or for operation in a residential environment), parties responsible for verification of the devices shall have the option of ensuring compliance with the applicable technical specifications of this chapter at each end user's location after installation, provided that the purchase or lease agreement includes a proviso that such a determination of compliance be made and is the responsibility of the party responsible for verification of the equipment. If the purchase or lease agreement contains this proviso and the responsible party has the product measured to ensure compliance at the end user's location, the product does not need to be labelled with the statement in paragraph (c) of this section.
