Digital Selective Calling (DSC)
Digital selective calling is a semi-automated system for establishing a radio
call. It has been designed by the International Maritime Organization (IMO)
as an international standard for VHF, MF, and HF calls and is part of the
Global Maritime Distress and Safety System (GMDSS).
DSC will eventually replace aural (listening) watches on distress frequencies
and will be used to announce routine and urgent maritime safety information
broadcasts. Until DSC is fully implemented, it is still necessary to maintain a
listening watch on Channel 16.
The DSC system allows mariners to instantly send a distress call with GPS
position coordinates (requires a GPS receiver to be connected to the radio)
to the Coast Guard and other vessels within range of the transmission.
DSC also allows mariners to initiate and receive distress, urgent, safety,
routine, position request, position send, and group calls between vessels
equipped with DSC capable radios.
