Automatic Identification System (AIS) Simulation

Working in conjunction with the US Coast Guard, BCG has developed an AIS message generator which is integrated into our MaST user interface. The simulated AIS messages can be output via a serial stream (RS232 or RS422), network UDP packets, or a network TCP stream. BCG's implementation of the AIS data packet generation is done in compliance with the ITU-R M.1371-5, IEC 61993-2, IEC 61162-1 and NMEA-0183 standards.

A simulation exercise may include up to 32 ownships and 1000 targets, each having defined AIS information. A library feature is provided for quick retrieval and storage of AIS information.

The MaST may also receive AIS messages via serial or network and includes the parsed information in an AIS message log window and log file. Text messages (SRM or Normal) can be sent/received and are logged in a separate text message log window.

The following AIS message types can be sent/received: 1, 4, 5, 6, 8, 9, 12, 13, 14, 18, 19, 21, 24, 25, 26, 27. The following AIS message types can be received only: 2, 3, 7, 11, 20.
