1.5 AIS – Automatic Identification System
AIS is an identification system that uses VHF communication to
transmit and receive AIS data. AIS operates primarily on two
dedicated VHF channels, AIS 1 – 161,975 MHz and AIS 2 – 162,025
MHz. Where these channels are not available regionally, the AIS can
be set to alternate designated channels.
The AIS mobile station broadcasts the vessel's position, speed and
course over ground as well as static and voyage related information.
Short safety related text messages can be sent between vessels or
broadcast from shore based AIS stations or Aids to Navigation like
buoys and lighthouses. The on-board installed mobile station is
designed to operate automatically and as a stand-alone unit. When not
transmitting, the mobile station listens for position information from
other vessels or shore based stations.
