🔍 Key Concepts

• F77 terminal identification format in the Global Maritime Distress and Safety System (GMDSS) • Meaning of MID (Maritime Identification Digits) in maritime mobile service identity numbers • Difference between 9-digit and 12-digit maritime numbers and how MIDs are positioned in them

💭 Think About

• Ask yourself: In standard maritime mobile service identities, where are the Maritime Identification Digits (MID) located—at the beginning, middle, or end of the number? • Consider whether an F77 terminal is associated with a specific equipment type that uses a 9-digit MMSI or a 12-digit number derived from an MMSI. • Think about which option correctly combines both length (9 or 12 digits) and the position of the MID for this particular type of terminal.

✅ Before You Answer

• Verify how many digits an MMSI (Maritime Mobile Service Identity) normally has for ships and coast stations. • Check where the MID appears in a standard MMSI (beginning or end). • Confirm whether an F77 terminal is identified by a normal 9-digit MMSI or by a derived 12-digit identifier that begins with the MID.
