Imagine a shipboard radar or an electronic chart display that includes a symbol for every significant ship within radio range, each with a velocity vector (indicating speed and heading). Each ship "symbol" can reflect the actual size of the ship, with position to GPS or differential GPS accuracy. By hovering over an AIS icon, you can learn the ship name, course and speed, classification, call sign, registration number, MMSI, and other information. Maneuvering information, closest point of approach (CPA), time to the closest point of approach (TCPA) and other navigation information, as relatively accurate and timely as information available from an automatic radar plotting aid, can also be available. Display information previously available only to modern Vessel Traffic Service operations centers can now be available to every AIS user. United States Coast Guard Navigation Center
