The Automatic Identification System (AIS) is an automatic tracking system
used on ships and by vessel traffic services (VTS) for identifying and
locating vessels by electronically exchanging data with other nearby ships
and AIS Base stations. The International Maritime Organization's (IMO)
International Convention for the Safety of Life at Sea requires AIS to be
fitted aboard international voyaging ships with gross tonnage (GT) of 300 or
more tons, and all passenger ships regardless of size.
