AIS stands for which of the following?

• A. Automated Identification System
• B. Automatic Identification System
• C. Advanced Identification System
• D. Automatic Information System

Answer: (A)

AIS stands for Automated Identification System. This maritime safety system automatically broadcasts a vessel’s identity and navigational data, such as the MMSI, ship name, vessel type, position, course, speed, and navigational status, so nearby ships and shore stations can identify and track it in real time. The information is transmitted over VHF channels and increasingly via satellite, supporting collision avoidance, traffic management, search-and-rescue, and port operations. The official designation used by the IMO and SOLAS is Automated Identification System; while you may hear variants, the precise term is Automated, not Automatic or Advanced, ensuring clarity in safety conventions and regulatory contexts.
