The Role of AIS Tracking Systems in Enhancing Maritime Operations

AIS Marine Traffic – AIS Tracking Systems Explained

How AIS Technology Transforms Maritime Safety and Efficiency

The Automatic Identification System (AIS) revolutionized maritime safety by combining GPS and VHF radio technologies, initially focusing on collision avoidance in poor visibility and at night. Over time, AIS evolved beyond its primary role, providing critical data for traffic services and coastal surveillance, especially for vessels out of shore-based systems’ reach. This evolution was significantly propelled by the introduction of satellite-based AIS receivers in 2008, expanding global maritime visibility and data accessibility. Today, AIS is indispensable, with a ship locator mandated for a wide range of vessels to enhance navigation, safety, and operational efficiency across the maritime industry.

AIS for Avoiding Collisions

The introduction of GPS for civilian purposes led to the first AIS vessel tracking and identification system. AIS was developed by integrating GPS time and position data with long-standing VHF radio technology. Initially developed under the International Maritime Organization (IMO) in the 1990s, AIS was as a ship-to-ship anti-collision system for use in poor visibility and at night, in support of radar and conventional watch keeping. Over time, the amount of information that could be transmitted in the VHF signal grew and its usefulness increased.

In its early years, AIS was useful for (1) avoiding collisions, (2) acting as a traffic service and (3) providing coastal surveillance. Of these, the main purpose was to prevent collisions by allowing vessels to see who else is operating in their immediate vicinity, which primarily concerned large vessels at sea outside the range of shore-based systems. The technology identifies every vessel individually, along with its specific position and movements, enabling a virtual picture to be created in real time. This was achieved by providing information on the ship’s identity, type, position, course, speed, navigational status and other safety-related information. The AIS standards have further improved to include a variety of automatic calculations based on these position reports, such as Closest Point of Approach (CPA) and collision alarms.

Since not all ships have the system, AIS is usually used in conjunction with radar. However, the use of AIS is increasing, as international maritime law requires AIS transponders to be fitted aboard international voyaging ships with a gross tonnage of 300 tonnes or more, and on all passenger ships regardless of their size. Further, given its visibility and safety advantages, many smaller vessels also voluntarily install AIS units. The result is that AIS is used almost universally in the worldwide commercial maritime industry, and increasingly so in the leisure marine sector.

AIS Transceivers: Class A and Class B

Today, the AIS system consists of a VHF transmitter, two VHF TDMA receivers, a VHF DSC receiver, and a communications link to shipboard displays and sensors. It uses GPS for position and timing information, with data being broadcast automatically to ensure seamless ship-to-ship and ship-to-shore communication.


AIS transceivers are divided into two categories: Class A and Class B, each differing in the volume of data reported and the frequency of reporting. Class A transceivers, mandatory for all international voyage ships above 300 gross tonnage and all passenger ships, broadcast various information, categorized into static, dynamic, and voyage-related data fields. Dynamic information, such as the ship’s speed and location, is transmitted every 2–10 seconds while underway and every 3 minutes while at anchor. Static and voyage-related details are shared every 6 minutes. In contrast, Class B transceivers, often used by smaller, primarily pleasure, vessels, transmit a reduced set of data at less frequent intervals. This differentiation ensures that the vast network of maritime traffic can communicate effectively, tailoring data sharing to the operational needs and capacities of different vessel types.

Evolution of AIS Data Collection

To improve the management of AIS marine traffic, the original AIS system relied heavily on direct ship-to-ship, ship-to-coast, and coast-to-ship communication within the very-high-frequency (VHF) radio wave range. This method, however, only covered 10–20 nautical miles, making AIS data difficult to collect and highly regionalized. Despite the limited horizontal range, AIS tracking systems have a much longer vertical transmission range, reaching up to 400 km. This enabled the significant leap forward in 2008 when AIS receivers were deployed on satellites. This development vastly increased the range, as satellites equipped with AIS receivers began to capture data transmitted by onboard AIS transceivers globally, enhancing the effectiveness of AIS tracking systems.

These satellites have dual roles. In busy port areas, they supplement terrestrial AIS receivers, enhancing AIS marine traffic management by providing comprehensive global coverage. Otherwise, ports risk becoming overwhelmed by the sheer volume of data from numerous vessels. Globally, they facilitate the collection of AIS data in almost real time, bridging the gap left by the limited range of terrestrial systems. Today, a number of online suppliers, leveraging the ship locator AIS feature, allow users to enter the names of vessels and find their locations on maps together with varying amounts of vessel and environmental information. Offshore positions collected via satellites are inherently more expensive, and typically available on commercial websites. This reflects the constantly improving quality and completeness of AIS data, showing how AIS has gone from direct ship-to-ship communication, evolving into offering a global perspective on maritime traffic.
