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). When satellites are used to receive AIS signatures, the term Satellite-AIS (S-AIS) is used.
Maritime identification digits are used by radio communication facilities to identify their home country or base area in digital selective calling (DSC), Automatic Transmitter Identification System (ATIS), and Automatic identification system (AIS) messages as part of their Maritime Mobile Service Identities.
An Electronic Navigational Chart (ENC) is a digital representation of a real-world geographical area for the purpose of Marine navigation.Real-world objects and areas of navigational significance, or to a lesser degree - informational significance, are portrayed through Raster facsimiles of traditional paper charts; or more commonly through vector images, which are able to scale their relative ...
These include the Automatic Identification System (AIS), Electronic Chart Display and Information System (ECDIS), Integrated Bridge Systems/Integrated Navigation Systems (IBS/INS), Automatic Radar Plotting Aids (ARPA), radio navigation, Long Range Identification and Tracking (LRIT) systems, Vessel Traffic Service (VTS) and the Global Maritime ...
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]
Craft Identification Number – a permanent unique fourteen-digit alphanumeric identifier issued to all marine vessels in Europe ENI number ( European Number of Identification or European Vessel Identification Number ) – a unique, eight-digit identifier for ships capable of navigating on inland European waters that is attached to a hull for ...
LRIT requires the active, willing participation of the vessel involved, which is, in and of itself, a very useful indication as to whether the vessel in question is a lawful actor. Thus the information collected from the two systems, S-AIS and LRIT, are mutually complementary, and S-AIS clearly does not make LRIT superfluous in any manner.
Information provided by AIS equipment, such as unique identification, position, course, and speed, is then transferred to the main Marine Traffic servers for display via the website in real time. The site uses data from OpenStreetMap on its base map, and the paid version lets users display ship locations on Nautical Charts.
