What does the term AIS stand for in navigation?

The term AIS stands for Automated Identification System. This system is crucial in modern maritime navigation as it provides automatic tracking of vessels through the exchange of information such as the ship's position, course, and speed. By utilizing VHF radio signals, AIS significantly enhances situational awareness and safety for both vessels and maritime traffic management.

The system allows vessels to broadcast their information in real-time without requiring manual input, thus making it highly efficient. This capability not only aids in collision avoidance but also helps in search and rescue operations, and improves the overall safety of navigation. The use of the term "Automated" accurately reflects the system's key feature of automating the communication necessary for safe maritime operations.
