Which of the following would indicate an Inmarsat-C terminal?

• A. A 9 digit number beginning with the MID.
• B. A 9 digit number always starting with 4.
• C. A 7 digit number.
• D. A 9 digit number always starting with 3.

Answer: (B)

The identification of an Inmarsat-C terminal is associated with a specific format of its number. The correct answer indicates a 9-digit number that always begins with the number 4. This prefix is a distinct characteristic that is used within the Inmarsat system to differentiate its various services and terminals. When a 9-digit number begins with 4, it signals that the terminal is part of the Inmarsat-C network, which is a satellite communication service widely used for vessel tracking and distress communication as part of the Global Maritime Distress and Safety System (GMDSS). Understanding this specific numbering helps users and operators to properly identify the terminal type and ensure they are utilizing the correct protocols for communication and service. This kind of knowledge is vital for maintaining effective communication at sea, especially in emergency situations.
