1 Overview
AIS Summarised Briefly
The Universal Shipborne Automatic Identification System (AIS) automatically provides the ship's nautical
officers with important information about nearby vessels or other relevant objects within VHF range.
The AIS system transmits own ship data cyclically via two defined VHF channels and receives the same
data of the other ships and objects that are equipped with AIS systems. The VHF channels in use can
be switched over by external commands via the integrated DSC receiver.
Based on SOLAS Chapter V - Safety of Navigation, a carriage requirement will enter into force for
different categories of ships. This obligation will be introduced step by step for different ship classes and
sizes, commencing on 1st July 2002 (all new vessels) and continuing until 1st July 2008 (all ships world-
wide having gross tonnages of at least 500 tons, and ships sailing internationally with gross tonnages of
at least 300 tons, but by 1st July 2007 at the latest). In addition, other vessels or objects to which the
provisions of regulations do not apply may be equipped on a voluntary basis.
Depending on the number of equipped vessels the degree of nautical safety is increased by AIS.
The System Components
The equipment described in these Operating Instructions is designed for installation on ships where such
installation is mandatory, and meets the relevant requirements. It consists of:
- the UAIS Electronics Unit DEBEG 3400, which contains complex electronics (including two VHF
transmitters, a DSC receiver, a GPS receiver and the data processor) but no operating or display
elements,
- the VHF antenna,
- the GPS antenna,
- the Display and Control Unit (DCU), on which the operating procedures described here take place,
connected to the Primary Display Port, and
- the 24 VDC power supply optionally connected to the ship’s emergency power supply which is
necessary for the Electronics Unit and DCU.
