Which of the following statements is TRUE regarding automatic identification systems (AIS)?
AI Explanation
The correct answer is A.
AIS is a short-range VHF-FM system that automatically broadcasts a vessel's position, course, speed and other safety-related information to all those with similar equipment in the area. This is the key function of AIS, which is a self-contained, automated system that does not require a centralized control or management. The other options are incorrect because B describes a radar system rather than VHF-FM, C describes a one-way centrally managed system which is not how AIS works, and D refers to a global tracking system using INMARSAT C, which is not the technology used for AIS.
