Abstract: The invention relates to an AIS data transmission method using AIS standard-compliant AIS signals. The AIS data (5) to be transmitted is converted into AIS signals on the transmitter side and transmitted via a main channel (41). The AIS signals are received in an AIS receiver (2, 3) and converted back into received AIS data (6, 7). Error-correcting redundancy data is generated from the AIS data (5) to be transmitted or from parts of said data on the transmitter side, and the redundancy data can be used on the receiver side to correct errors of the received AIS data (6, 7). The redundancy data is converted into redundancy signals on the transmitter side and transmitted via an auxiliary channel (42) provided in addition to the main channel (41). The invention further relates to a corresponding AIS transmitter, a corresponding AIS receiver, and an AIS transceiver. The invention further relates to a system consisting of AIS transmitters and AIS receivers and to a computer program.
