Global Maritime Distress and Safety Systems (GMDSS) provide unified, standardised communication procedures and equipment to manage emergencies at sea. Covering VHF and MF/HF radios, Inmarsat satellite connections, NAVTEX receivers, and emergency position-indicating radio beacons, GMDSS ensures quick delivery of distress alerts and vital safety messages. As a key aspect of SOLAS compliance, GMDSS improves crew safety by coordinating search and rescue efforts and maintaining consistent communication across all maritime zones.
