🔍 Key Concepts
• Maritime Mobile Service Identity (MMSI) is a unique digital number assigned mainly to ships and some coast stations
• Different ITU (International Telecommunication Union) lists cover different types of stations: ship stations, coast stations, and radionavigation/other services
• Think about which ITU publication would logically pair ship names with their assigned MMSI numbers
💭 Think About
• Ask yourself: Is an MMSI primarily associated with a ship station, a coast station, or a shore facility plan?
• Look at each choice and match it with what type of station or information it usually lists (ships, coast stations, shore-based facilities, or radio-determination).
• Which option specifically mentions both ship stations and MMSI assignments, which is exactly what you need to link a number to a vessel name?
✅ Before You Answer
• Confirm which publication is used to look up ship station details such as name, call sign, and MMSI
• Make sure the reference explicitly deals with MMSI assignments, not just frequencies or facility locations
• Eliminate any option that focuses mainly on coast stations or general shore-based facilities, rather than ships themselves
