Which is not a sensor for AIS vessel movement?

• A. Fire Control Radar
• B. RDOP
• C. Watch Keeper
• D. C2PC

Answer: (A)

The central idea is that AIS vessel movement data comes from the AIS system itself (and tools that fuse or display that data) rather than from generic “systems” or operator roles. A fire control radar is a traditional targeting radar used to detect and track objects for engagement or navigation, but it does not provide AIS movement data. It operates independently of the AIS data stream and isn’t a source for AIS vessel movement information. The other items are software or roles that support AIS awareness rather than serving as a raw AIS sensor themselves: a radar data overlay processor integrates radar information with AIS to present a composite picture; a watch-keeper is the person monitoring the display; and C2PC is a command-and-control software that organizes and disseminates movement data. So, among the options, the fire control radar is not a sensor used to obtain AIS vessel movement data.
