What is Inmarsat C?

Inmarsat C is a global satellite communication system developed by Inmarsat to provide reliable connectivity at sea, regardless of the vessel’s location. Designed to enhance safety, navigation, and effective communication in both routine and emergency situations, Inmarsat C plays a vital role in the Global Maritime Distress and Safety System (GMDSS), serving as one of its core communication technologies.

How Does Inmarsat C Work?

The system operates through four geostationary satellites orbiting the equator, providing global coverage. Each satellite is supported by Land Earth Stations (LES) and Network Coordination Stations (NCS), which manage data transmissions. Communication between ship terminals and land-based recipients is facilitated through these satellites, ensuring independence from traditional terrestrial infrastructure.

Key Functions of Inmarsat C:

  • Sending and Receiving Text Messages: Users can send text messages to other terminals, email addresses, and fax numbers.
  • Position Reporting: The system enables regular transmission of the vessel’s position (GPS data), allowing real-time tracking.
  • Enhanced Group Calling (EGC): The system supports receiving information such as:
    • Navigational warnings, e.g., hazards along the route.
    • Weather forecasts and warnings for severe conditions.
    • Other navigation safety messages (SafetyNET).
  • Distress Alerting: Inmarsat C allows sending distress alerts to Maritime Rescue Coordination Centers (MRCC) to request assistance in life-threatening situations.

Applications of Inmarsat C in Maritime Navigation

Inmarsat C was introduced to support maritime safety and complies with the international SOLAS regulations (International Convention for the Safety of Life at Sea). Thanks to its reliability and user-friendliness, it is widely used on commercial, fishing, and recreational vessels. Terminals like the SAILOR 6110 mini-C GMDSS have become standard equipment, enabling communication and meeting legal safety requirements.

Why is Inmarsat C Important?

Inmarsat C stands out for its high reliability and global coverage, making it an ideal solution for vessels operating anywhere in the world. Even in areas where traditional radio systems or cellular networks fail, Inmarsat C ensures continuous communication. This is particularly crucial in emergencies, where rapid response and effective information exchange can save lives.

Inmarsat C Terminals: A Key to Safety

The Inmarsat C system is utilized in a wide range of communication devices, such as the SAILOR 6110 mini-C GMDSS, which fully leverages this technology to ensure safety and reliable communication at sea.
