How AIS Works

Automatic Identification System (AIS) is a reporting system used in the

identification of marine vessels and its location. Vessels equipped with this

system allows each other to communicate automatically, dynamically and

regularly update their position, speed, course and information such as vessel

identity.

How does AIS function as a radar?

The AIS radar function does not refer to its own AIS system and its features

such as the VHF T/R and Letter Machine but by serial interface through

(NMEA) which will be received by the AIS and sent to the radar on a real

time displayed on the radar screen.
