Coastal Surveillance

In coastal waters, shoreside authorities may establish automated AIS stations to monitor

the movement of vessels through the area. These stations may simply monitor AIS

transmissions from passing ships, or may actively poll vessels via the AIS channels,

requesting data such as identification, destination, ETA, type of cargo and other

information.

Coast stations can also use the AIS channels for shore-to-ship transmissions, to send

information on tides, notices to mariners and local weather forecasts. Multiple AIS

coast stations and repeaters may be tied together into Wide Area Networks (WAN) for

extended coverage.

Coastal nations may use AIS to monitor the movement of hazardous cargoes and

control commercial fishing operations in their territorial waters. AIS data can be logged

automatically for playback in investigating an accident, oil spill or other event. AIS is

also a useful tool in search and rescue (SAR) operations, allowing SAR coordinators

to monitor the movements of all surface ships, aircraft and helicopters involved in the

rescue effort.

Vessel Trafc Systems

When integrated with shore-based vessel traffic systems (VTS), AIS provides a powerful

tool for monitoring and controlling the movement of vessels through restricted harbors

and waterways. The AIS can augment traditional radar-based VTS installations, providing

an AIS “overlay” on the radar picture, or can provide a cost-effective alternative in areas

where it is not feasible to establish radar-based systems. When integrated with radar,

the AIS can ensure continuous coverage, even when the radar picture is degraded by

heavy precipitation or other interference.

The AIS channels can be used to transmit port data, pilotage, berth assignments,
