Q

Which of the following would indicate an F77 terminal?

🔍 Key Concepts

• Inmarsat terminal types and how they are encoded in MMSI or ID numbers • How the first few digits of a terminal or ship earth station number relate to the type of equipment (e.g., F77, mini-M, etc.) • Patterns in maritime ID numbers used for satellite communication terminals

💭 Think About

• Look at the leading digits of each choice. Which prefix is typically associated with an F77 (Fleet 77) satellite terminal rather than another service or region? • Consider what kind of numbering scheme is used for satellite ship earth stations. Do certain services cluster around specific 3-digit prefixes? • Ask yourself: if I group these by their first three digits, which group aligns with known Fleet 77 / F77 identifiers?

✅ Before You Answer

• Verify which 3‑digit prefix is assigned to F77 terminals in your reference materials or study guide • Confirm that the length and overall format of the number matches a typical F77 ID (not, for example, a standard ship MMSI or other terminal type) • Double-check in a GMDSS/Inmarsat reference table which prefixes belong to Fleet 77 vs other Inmarsat services
