About AIS AIS 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), the location, the GPS speed, the GPS heading, the time that has elapsed since the last position of the vessel was reported, the nearest approach, and the time to the nearest approach.

About AIS
AIS 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), the location, the GPS speed, the GPS heading,
the time that has elapsed since the last position of the vessel was
reported, the nearest approach, and the time to the nearest approach.
