MMSI supplies identity · valid position is included only when it reaches the radio

Position is included only when valid position data reaches the radio.

Digital Selective Calling allows compatible radios to transmit digitally encoded calls.

A DSC-equipped VHF can support:

distress alerting

individual calling

group calling

position-related functions where supported

The major safety benefit is that a properly configured distress alert can transmit the vessel's identity and, when position data is available to the radio, its position.
