An AIS-equipped system on board a ship presents the bearing and distance of nearby vessels in a radar-like display format. A graphical display of AIS data on board a ship. The automatic identification system (AIS) is an automatic tracking system that uses transceivers on ships and is used by vessel traffic services (VTS).
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]
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 ...
Ship watching using a telescope. Watching ships that pass through the Uraga Channel, at Kannonzaki Park, Yokosuka, Japan. Ship watching or ship spotting is a form of outdoor activity and tourism that is carried out worldwide by observing and photograph various ships in the waterways where there is a lot of ship traffic.
The LRIT regulation will apply to the following ship types engaged on international voyages: All passenger ships including high-speed craft, Cargo ships, including high-speed craft of 300 gross tonnage and above, and; Mobile offshore drilling units. These ships must report their position to their flag administration at least four times a day.
AtoNs can be integrated with automatic identification system (AIS). AIS transmitted form an actual aid (buoy, lighthouse etc.) is termed a "real AIS AtoN". [11] If it is impractical to equip the AtoN with an AIS transponder an AIS shore station can be assigned to transmit AIS messages on behalf of the AtoN. This is known as a "synthetic ATON".
When the vessel enters the waters of a different state, the home FMC must forward the report of the vessel's entry into those waters to the foreign state FMC. Until the vessel leaves the foreign state's coastal area, the home FMC must forward to the foreign state FMC the position, speed, and course reports at least every two hours.
Land areas are shown in yellow, and vessel tracks are displayed with green "tails" on the screen. Marine radar systems can provide very useful radar navigation information for navigators on board ships. The ship's position could be fixed by the bearing and distance information of a fixed, reliable target on the radar screen.
