The transceiver (1) has a transmitter unit (2) for transmitting the AIS radio signals (AIS1-AIS2,AIS3-AIS4) in response to the message (Message4) received in AIS ground station (12). A receiving unit (3) receives the AIS-radio signals (AIS1-AIS2) of adjacent ships (10) and message of stations. A database (7) stores the data relating to a valid station. A control unit (4) validates the signals according to message of stations as a function of message and stored data, and emits a portion of the signals as a function of validation to deactivate and activate the station. An independent claim is included for a method for transmitting and receiving AIS radio signals.
