The technology identifies every vessel individually, along with its specific position and movements, enabling a virtual picture to be created in real time. The AIS standards include a variety of automatic calculations based on these position reports such as Closest Point of Approach (CPA) and collision alarms.
Canada intends to provide, in real time, VMS data, correlated with other sensors and database information, to patrol vessels and aircraft. Electronic logs, two-way communication with fishing vessels, issuing orders, and possibly placing video and other sensors on fishing.
MarineTraffic is a maritime analytics provider, [1] which provides real-time information on the movements of ships and the current location of ships in harbors and ports. [2] A database of information on the vessels includes for example details of the location where they were built plus dimensions of the vessels, gross tonnage and International ...
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 ...
An information service is a service to ensure that essential information becomes available in time for onboard navigational decision-making. The information service is provided by broadcasting information at fixed times and intervals or when deemed necessary by the vessel traffic service or at the request of a vessel, and may include for example reports on the position, identity and intentions ...
An upgraded vessel tracking system, which can track 4,000 moving vessels plus 1,000 stationary targets in real time, has been in operation since early 2002. It provides the latest technology such as AIS , ECDIS , CCTV , new VHF-direction finders and modern communications systems to further improve navigation safety and operation efficiency.
Mini-automatic radar plotting aid (or MARPA) is a maritime radar feature for target tracking and collision avoidance. Targets must be manually selected, but are then tracked automatically, including range, bearing, target speed, target direction (course), CPA (closest point of approach), and TCPA (time of closest point of approach), safe or dangerous indication, and proximity alarm.
The vessel has many small radomes for various communications tasks and a large central dome that encloses a phased-array, 1,800 tonne (4,000,000 pound) X-band radar antenna. The small radomes are rigid, but the central dome is not - the flexible cover is supported by positive air pressure amounting to a few inches of water.
