SRT has been a global leader in professional radio communication technology development since 1987, and since 1999 the world's leading developer of AIS technologies and products. SRT offers a full range of customisable AIS technology, product, network and display solutions, supported by unmatched experience and capability in maritime domain awareness.
Our solutions address all aspects of maritime domain awareness and make full use of the evolving AIS technology standards to deliver reliable and consistent functionality.
Automatic Identification System (AIS)
The Automatic Identification System (AIS) is an automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships, AIS base stations, and satellites. When satellites are used to detect AIS signatures then the term Satellite-AIS (S-AIS) is used. AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.
Vessels fitted with AIS transceivers and transponders can be tracked by AIS base stations located along coast lines or, when out of range of terrestrial networks, through a growing number of satellites that are fitted with special AIS receivers which are capable of de-conflicting a large number of signatures.
The International Maritime Organization's International Convention for the Safety of Life at Sea requires AIS to be fitted aboard international voyaging ships with gross tonnage (GT) of 300 or more, and all passenger ships regardless of size.
Aids to navigation (AtoN) and Marine Mammal Detection
The AIS Aids to Navigation (AtoN) product standard was developed with the ability to broadcast the positions and names of objects other than vessels, such as navigational aid and marker positions and dynamic data reflecting the marker's environment (e.g., currents and climatic conditions). These aids can be located on shore, such as in a lighthouse, or on water, platforms, or buoys.
AtoN's enable authorities to remotely monitor the status of a buoy, such as the status of the lantern, as well as transmit live data from sensors (such as weather and sea state) located on the buoy back to vessels fitted with AIS transceivers or local authorities. An AtoN will broadcast its position and Identity along with all the other information. The AtoN standard also permits the transmit of 'Virtual AtoN' positions whereby a single device may transmit messages with a 'false' position such that an AtoN marker appears on electronic charts, although a physical AtoN may not be present at that location.
Fastwave has developed a unique method of using "Virtual Aton" positions to indicate the location of marine mammals to vessels in the area. This is illustrated below. Please contact Fastwave for further information.
