Q

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

🔍 Key Concepts

• Structure of Inmarsat Mobile Numbers (IMN) – 9 digits with a service identifier at the beginning • Different first‑digit ranges for Inmarsat A/B/M vs Inmarsat‑C terminals • How GMDSS uses specific Inmarsat systems (A, B, C, Fleet) and assigns distinct number blocks

💭 Think About

• Look at the first digit of each option and recall which digit range is allocated to Inmarsat‑C terminals in the ITU/INMARSAT numbering plan • Eliminate any option whose starting digit you know is used for other Inmarsat services or for non‑Inmarsat maritime numbers • Think about examples you may have seen of real Inmarsat‑C terminal IDs in training materials or past exam questions – what do they usually start with?

✅ Before You Answer

• Verify which leading digit(s) in a 9‑digit IMN are reserved for Inmarsat‑C in your study references or ITU lists • Confirm that the option you choose is a 9‑digit number with the correct service identifier at the beginning • Make sure you are not confusing an MMSI (Maritime Mobile Service Identity) with an Inmarsat terminal number – they follow different allocation rules
