AIS stands for Automatic Identification System. It is a system used in the maritime industry to track and monitor the movements of ships and boats. AIS technology allows vessels to exchange information, such as their identity, position, course, speed, and other relevant data, with other nearby vessels and shore-based stations. This information is typically transmitted over VHF (Very High Frequency) radio waves and is used for collision avoidance, navigation, and maritime safety.

AIS is a valuable tool for improving situational awareness on the water, as it enables ship operators, maritime authorities, and other stakeholders to track vessel movements in real-time. It is especially important in congested or high-traffic areas, such as busy ports and shipping lanes, to prevent collisions and enhance overall maritime security.

There are two types of AIS devices:
  • AIS Transponders: These are installed on vessels and continuously broadcast information about the vessel’s identity, position, speed, and course. They can also receive and display information from other nearby vessels.

  • AIS Base Stations: These are shore-based or land-based stations that receive AIS signals from vessels in their vicinity and relay that information to a central monitoring system or other vessels. Base stations can also send safety-related messages to vessels.
AIS has become a standard technology in the maritime industry and is mandated by international regulations, making it an essential tool for enhancing maritime safety and efficiency.
