INMARSAT-C
Inmarsat-C is a reliable satellite communication system used on ships for global messaging, distress alerting, and maritime safety communication. It operates through the satellite network of Inmarsat, providing vessels with worldwide coverage even in remote ocean areas. The system is an important part of the GMDSS (Global Maritime Distress and Safety System), allowing ships to send distress alerts, receive safety messages, and communicate with shore authorities. Inmarsat-C terminals also receive SafetyNET maritime safety information, including navigational warnings and weather forecasts
