Class A transceivers

Class A AIS transceivers transmit and receive AIS signals. AIS transceivers are currently mandatory on all commercial vessels exceeding 300 tons that travel internationally (SOLAS vessels).

The following information can be transmitted by a Class A AIS system:

  • Static data (Includes information such as MMSI number, vessel name, vessel type, call sign, IMO number, length, beam and GNSS antenna location).

  • Voyage related data (Includes information such as draft, cargo, destination, ETA and other relevant information).

  • Dynamic data (Includes information such as time (UTC), ship’s position, COG, SOG, heading, rate of turn and navigational status).

  • Dynamic reports (Ship’s speed and status).

  • Messages (Alarms and safety messages).

Remember that not all vessels will transmit all of the information.
