Satellite – Automatic Identification System (SAT-AIS) Overview
artes.esa.int › satellite-–-automaticSatellite – Automatic Identification System (SAT-AIS) Overview. The Automatic Identification System (AIS) is a short-range coastal tracking system currently used on ships. It was developed to provide identification and positioning information to both vessels and shore stations. Ships of 300 gross tonnage or more sailing on international voyages, cargo ships of 500 gross tonnage or more sailing in local waters, and all passenger ships irrespective of size are mandated by the International ...

Automatic identification system - Wikipedia
en.wikipedia.org › Automatic_identification_systemThe automatic identification system ( AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport. [citation needed]

AIS reports are digitally compressed data packets which are then transmitted through VHF radio signals. These VHF radio signals are openly broadcast to be picked up by other vessels, land-based antennae and, bridge to bridge locations which use AIS as a collision avoidance tool. If not in range these signals are then picked up by satellites.
