Automatic Identification System
AIS and other broadcast messages are intended for situational awareness only and may not prevent collisions in all circumstances. You are responsible for the safe and prudent operation of your vessel, for remaining aware of your surroundings, and for using safe judgment on the water at all times.
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.
In addition to receiving AIS information from vessels, you can also receive important broadcast messages, such as those sent for protection of marine mammals.
AIS broadcast messages are generated by third parties, and Garmin cannot guarantee the availability of these messages in all regions. Additionally, Garmin makes no representations about the accuracy, completeness, or timeliness of information provided by AIS broadcast messages. You must remain aware of your surroundings at all times, and any use or reliance on the information provided by AIS broadcast messages is at your own risk.
