A global maritime distress and safety system (GMDSS) is a maritime communications system for all vessels. A total GMDSS system is made up of:
- digital selective calling (DSC) via radio
- satellite communications
- Navtex - weather and transport information
- search and rescue radar transponders (SARTs)
- emergency position indicating radio beacons (EPIRBs)
A pleasure craft may not need a complete GMDSS package but MCA recommends that owners and operators make sure they at least fit a VHF DSC radio.
