Which of the following best describes Inmarsat-C operation?

• A. Is an analog-based system.
• B. Requires a stabilized directional antenna.
• C. Provides for voice, TELEX, high and low-speed data and compressed video communications.
• D. Is a digital store-and-forward system that also provides Enhanced Group Call, data reporting, polling and Distress alerting capabilities.

Answer: (D)

Inmarsat-C is indeed best described as a digital store-and-forward system. This means that the system is designed to receive and store data before forwarding it to the intended destination. It is capable of handling various types of communications, including distress alerting, which is a vital feature for safety at sea. Enhanced Group Call (EGC) services are also provided, allowing for efficient distribution of information to multiple users. The system's ability to support data reporting and polling further enhances its utility for maritime operations, making it a versatile choice for vessel communication. This choice reflects the technological capabilities and operational characteristics specific to Inmarsat-C, emphasizing its digital functionality and advanced communication features. The integration of these elements makes Inmarsat-C particularly valuable for vessels operating in remote areas, where reliable communication is essential.
