Automatic Identification System (AIS)

The Automatic Identification System provides fast, automatic and accurate information in order to reduce the risk of collisions.

What is an AIS?

Automatic Identification System (AIS) is an autonomous and continuous broadcast system, operating in the VHF maritime mobile band. It exchanges information such as vessel identification, position, course, speed, etc. between participating vessels and shore stations. It can handle multiple reports at rapid update rates, using Time Division Multiple Access (TDMA) technology to meet these high broadcast rates, ensuring reliable and robust operation. Chapter V of the 1974 SOLAS Convention (as amended) requires mandatory carriage of Automatic Identification System (AIS) equipment on all vessels constructed on or after 01 July 2002. Implementation for other types and sizes of SOLAS Convention vessels is continuing and is required to be completed not later than 31 December 2004.
