Q

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

🔍 Key Concepts

• Inmarsat-C terminals and IMN (Inmarsat Mobile Number) formats • Difference between MMSI (Maritime Mobile Service Identity) and Inmarsat numbers • Typical leading digits used for Inmarsat-B, Inmarsat-C, and other Inmarsat services

💭 Think About

• Which of these options looks like an MMSI format rather than an Inmarsat terminal number? Think about how MMSIs use the Maritime Identification Digits (MID). • Among the remaining choices, identify which leading digits are commonly associated with Inmarsat mobile numbers used for store-and-forward data and safety services (Inmarsat-C). • Try recalling which Inmarsat service used numbers starting with 870/871 versus special prefixes like 970, and see which choice best matches Inmarsat-C.

✅ Before You Answer

• Verify which option explicitly mentions MID, and recall that MID is part of MMSI, not an Inmarsat terminal ID. • Check which starting digits are known to belong to Inmarsat-B rather than Inmarsat-C, so you can rule that out. • Confirm which specific 9-digit prefix is taught in GMDSS/Inmarsat exam prep materials as the standard indicator of an Inmarsat-C terminal.
