I f an external GNSS device which does not provide a DTM
sentence is connected to the AIS transceiver and the AIS
transceiver is configured to require DTM sentences, the
external GNSS data will not be accepted by the AIS

datum will be used as a coordinate origin and the
external GNSS device must be configured to output
position using this datum.
