AIS (Automatic Identification System)
AIS is an acronym for “Automatic Identification System.”
An AIS transponder is a short range data radio unit, used primarily for collision-risk management and navigation
safety. It automatically transmits and receives vessel information such as the vessel name, MMSI code, vessel
type, position data, speed, course, destination and more. Information is exchanged among the vessels and/or
base stations on the VHF maritime mobile band. The information helps to identify other nearby vessels or stations
by displaying the received data on the radar screen.
