Automatic Identification System
The Automatic Identification System (AIS) enables you to identify and track other vessels, and alerts you to
area traffic. When connected to an external AIS device, the chartplotter can show some AIS information about
other vessels that are within range, that are equipped with a transponder, and that are actively transmitting AIS
information.
The information reported for each vessel includes the Maritime Mobile Service Identity (MMSI), location, GPS
speed, GPS heading, time that has elapsed since the last position of the vessel was reported, nearest approach,
and time to the nearest approach.
Some chartplotter models also support Blue Force Tracking. Vessels being tracked with Blue Force Tracking
are indicated on the chartplotter with a blue-green color.
