A marine safety radio system for all mariners
The GMDSS has automated many marine radio functions and processes, particularly those related to distress and safety.
The GMDSS is an amalgam of a number of individual radio systems. Whilst satellite-based systems do play a part in the GMDSS, ‘normal’ terrestrial radio continues as the primary system for ship-ship and ship-shore communications.
GMDSS has automated marine radio
distress alerting by the use of a
technology known as Digital
Selective Calling (DSC).
This web site has been established to provide a single point resource on DSC, with a particular focus on VHF DSC and its use by recreational boaters.
We explain how DSC works, what you can use it for, and why you should seriously consider fitting it to your boat and/or limited coast station.
