AIS is the satellite system VTS (vessel tracking service) uses to track ships.
Automatic Identification System (AIS) uses VHF radio signals to exchange information between vessels and shore stations to improve navigation safety.
An example of Automatic Identification System is a ship transmitting its position, speed, and other data to nearby vessels and shore stations.
The benefits of Automatic Identification System include increased safety, improved efficiency, and enhanced situational awareness for vessels and maritime authorities.
The basic principle of AIS is to continuously broadcast and receive vessel information over VHF frequencies.
AIS can see up to approximately 40 nautical miles depending on antenna height and atmospheric conditions.
AIS data is collected by shore stations and satellites, which transmit the information to users.
The main difference between AIS and ARPA (Automatic Radar Plotting Aid) is that AIS uses radio signals to exchange information between vessels, while ARPA uses radar.
AIS data is not generally considered public, but it can be accessed by authorized maritime authorities and service providers.
The three types of information provided by AIS include vessel identity, position, and voyage information.
AIS can be integrated with GPS to provide accurate position information.
The accuracy of AIS can vary depending on the quality of the equipment and the conditions in which it is used.
AIS data can be transmitted via satellite to provide coverage in remote areas where shore stations are not available.
AIS is a global system, but coverage may vary depending on the location and availability of shore stations and satellites.
