About AIS

The automatic identification system, or AIS, transmits a ship’s position so that other mariners and fleet managers are aware of its position.

The International Maritime Organization and other regulatory bodies require large ships to broadcast their position with AIS for collision avoidance and as an anti-piracy measure.

Each year, more than 400,000 AIS devices broadcast vessel location, identity, course and speed information.

Ground stations and satellites pick up this information, making vessels trackable even in the most remote areas. National coast guards, government regulators, maritime firms, noncommercial vessel operators and insurance companies around the world are among those who monitor the maps, the live data or the extensive data archive.
