How does AIS work?

The Automatic Identification System (AIS) is a radio frequency-based monitoring system employed by nautical vessels to share pertinent details about their identification, location, and additional information with other ships and coastal stations operating within its coverage range. AIS makes use of devices like transponders that are affixed to ships or stationary stations, along with a network framework for sending and receiving communications.


To implement AIS, ships need to install AIS transponders, and shore-based stations called AIS base stations need to be set up. These base stations have antennas that receive AIS signals from nearby vessels and transmit them to an AIS server. The server then processes and stores the received information, which users can access through an AIS client application.


The primary objective of AIS is to facilitate the monitoring and recognition of maritime vessels. Each ship that is equipped with AIS regularly transmits AIS signals that include details such as its location, velocity, direction, and navigational condition. These signals are received by neighboring vessels and land-based stations, granting them the ability to observe and supervise the activities of the broadcasting ship.

Compliance and Regulation

International regulations mandate the utilization of AIS systems for specific categories of vessels, including sizable commercial ships and passenger vessels. These regulations establish the precise technical specifications and performance criteria that AIS equipment needs to satisfy. By adhering to these regulations, vessels can guarantee their visibility to other ships, thereby contributing to the maintenance of safety in congested maritime zones.

Exchange and Display of Information

Exchange and Display of Information

By exchanging AIS messages, ships and land stations can obtain up-to-date details regarding the whereabouts and motions of nearby vessels. This data can be showcased on radar screens equipped with AIS functionality or incorporated into navigation systems. It empowers operators to make well-informed choices and implement vital measures to prevent accidents and enhance situational perception.

To sum up, AIS is a wireless technology that facilitates the exchange of information and tracking of ships. It involves the use of AIS transponders installed on vessels and base stations, and adheres to international regulations to ensure high standards of performance and specifications. AIS serves as a valuable resource for maritime operators in improving safety and efficiency in ship navigation.
