Which type of communication system uses satellite technology to enhance maritime safety?

The communication system that utilizes satellite technology to enhance maritime safety is INMARSAT. This satellite communication service plays a crucial role in providing reliable and continuous connectivity for vessels at sea. INMARSAT offers voice and data services, which are indispensable for navigational safety, emergency communications, and routine operational needs.

Unlike traditional VHF and UHF radios that operate within line-of-sight range and can be limited by distance and obstacles, INMARSAT's satellite-based system allows for global coverage. This means that vessels can maintain communication regardless of their location on the open sea, which is essential for safety operations, reporting maritime emergencies, and coordinating search and rescue missions.

Moreover, CW (Continuous Wave) communication is an older method primarily used for Morse code transmissions and does not involve satellite technology. Therefore, while it does serve a purpose in maritime communication, it does not enhance safety through satellite capabilities as INMARSAT does.
