AIS is short for Automatic Identification System. The International Convention for Safety of Life At Sea (SOLAS) requires all vessels greater than 300 tons and all passenger vessels to be equipped with AIS Transponders. All vessels equipped with AIS permanently broadcast via one or more of the two dedicated VHF channels. This transmission may include information about the vessels MMSI- number, its call sign, name, position, course, heading, speed, rate of turn and type of vessel.
This unit can receive and display AIS information when connected to an AIS receiver. Available AIS vessels transmitting in the local area are show on the chart when this feature is enabled.
The following AIS receivers are supported by this unit:
•Comar SLR200 (external GPS).
•Weatherdock Two Channel AIS Receiver “EASY AIS”, Part No.
