What does the term "AIS" stand for, and what is its function?

The term "AIS" stands for Automatic Identification System, and it plays a crucial role in maritime navigation and safety. This system enables vessels to automatically transmit and receive data concerning their identity, position, course, speed, and other navigational details. The primary function of AIS is to enhance the situational awareness of vessels, allowing them to track the movements of other ships, thus reducing the risk of collisions and improving overall maritime safety.

Additionally, the information provided by AIS is essential for vessel traffic services, enabling authorities to monitor marine traffic more effectively and manage maritime operations. By facilitating communication between vessels and between vessels and shore-based facilities, AIS contributes to efficient navigation and safety management in congested waterways.
