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.
