Abstract
Automatic Identification System (AIS) is a
significant development in navigation safety since
the introduction of RADAR. It was originally
developed as a collision avoidance tool for
commercial vessels to improve the helmsman’s
information about his surrounding environment. AIS
does this by continuously transmitting a vessels
identity, position, speed and course along with other
relevant information to all other AIS equipped
vessels within range
