Which system is used to track and monitor ship movements?

The Automatic Identification System (AIS) is specifically designed for tracking and monitoring the movements of ships and vessels. It provides real-time information regarding a vessel's position, course, speed, and other relevant maritime data, which is crucial for navigation safety and situational awareness. AIS operates by broadcasting the data from the ship to other vessels and shore stations, allowing nearby ships to receive this information and reduce the risk of collisions. The system plays an integral role in maritime traffic management and enhances the ability of vessels to communicate their movements effectively within busy shipping lanes.

While Global Positioning System (GPS), Radar Navigation System (RNS), and Electronic Chart Display and Information System (ECDIS) also contribute to navigation, they serve different functions. GPS provides location determination, RNS assists in detecting other vessels and land features, and ECDIS combines navigational charts with electronic data. However, AIS is the specific system aimed at tracking and monitoring vessel movements by sharing positional data with other users.
