Terrestrial AIS

Terrestrial Automatic Identification System (AIS) is a global standard for ship-to-shore, and shore-to-ship communications and contributes to collision avoidance, search and rescue operations, and maritime domain awareness through vessel tracking.

AIS has been mandatory since the International Maritime Organization’s (IMO) 1974 Internaitonal Convention for the Safety of Life at Sea (SOLAS). Through terrestrial AIS, signals are transmitted to coastal stations. Combining terrestrial and satellite AIS coverage makes for a more robust vessel tracking system.
