Which equipment is listed as used by the Coast Guard for COMSATCOM?

• A. INMARSAT A, B, C and MINI-M terminals
• B. GPS receivers
• C. HF radios
• D. VHF transceivers

Answer: (A)

COMSATCOM relies on satellite-based links to maintain global communications at sea. The Coast Guard lists Inmarsat terminals—A, B, C and Mini—as the equipment for COMSATCOM because these terminals directly access the Inmarsat satellite network to provide voice and data services beyond line-of-sight. GPS receivers, HF radios, and VHF transceivers serve other purposes: navigation, long-range non-satellite radio communication, and near-shore or line-of-sight messages, respectively. So, Inmarsat terminals are the equipment tied to COMSATCOM.
