The long-range identification and tracking (LRIT) of ships was established as an international system on 19 May 2006 by the International Maritime Organization (IMO) as resolution MSC.202 (81). [1] This resolution amends Chapter V of the International Convention for the Safety of Life at Sea (SOLAS) , regulation 19-1 and binds all governments ...
When AIS data is fused with existing radar systems, authorities are able to differentiate between vessels more easily. AIS data can be automatically processed to create normalized activity patterns for individual vessels, which when breached, create an alert, thus highlighting potential threats for more efficient use of security assets.
The Maritime Safety & Security Information System (MSSIS) is a freely-shared, unclassified, near real-time data collection and distribution network. Its member countries share data from Automatic Identification System (AIS), coastal radar, and other maritime-related systems. [1]
Inmarsat F77, an updated version of the now redundant Inmarsat A and B, provide ship-to-shore, ship-to-ship and shore-to-ship telephone, telex and high-speed data services, including a distress priority telephone and telex service to and from rescue coordination centers. Fleet 77 fully supports the Global Maritime Distress and Safety System ...
Automatic Identification System – AIS is an IMO supported technology – provides low cost dual terrestrial and long-range satellite maritime data communications. It offers a base level of VMS functionality with global coverage at the lowest cost.
Lloyd's List Intelligence (formerly Lloyd's MIU LLC) is an information service dedicated to the global maritime community. It is a sister company of Lloyd's List. [1]Lloyd's List Intelligence is an interactive online service offering detailed vessel movements, real-time AIS positioning, information on ships, companies, ports and casualties as well as credit reports, industry data and analysis ...
Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.
A typical shipboard ARPA/radar system. A marine radar with automatic radar plotting aid (ARPA) capability can create tracks using radar contacts. [1] [2] The system can calculate the tracked object's course, speed and closest point of approach [3] (CPA), thereby knowing if there is a danger of collision with the other ship or landmass.
