This contrasts to the Automatic identification system (AIS) used globally on ships that transmit continuously. A short post-transmission message is sent by the radio with the vessel identity and is in the form of an encoded call sign or Maritime Mobile Service Identity , starting with number "9" and the three country-specific maritime ...
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).
STM seeks to create an organized traffic management entity called Sea Traffic Coordination Center(STCC) that will act as a central hub maintaining a record of all vessels at sea using the AIS and/or radar, enabling the distribution of vessel routes between ship-to-ship and ship-to-shore. The STCC together with the AIS and/or radar allows:
A recent IMO regulation requires AIS transponders aboard vessels, which transmit identifier, name and position of vessels not limited to fishing. [31] Another approach might involve either AIS, or the more finely grained VTS, agreements that use coastal radar to monitor ships in and beyond coastal waters.
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 ...
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".
