Satellite AIS for Global Vessel Surveillance
Historically, the detection of AIS transmissions was limited by Line Of Sight (LOS) radio wave propagation, and the proximity of AIS surveillance assets, either vessel, airborne or shore based.
Vessels operators and national authorities that wished to identify and monitor vessels at long range (50 NM to Unlimited) were forced to rely on traditional satellite tracking methods. These were expensive to own and operate, and typically were highly collaborative. Access to this data was difficult to obtain unless a commercial agreement was in place, and certain vessel operators were unwilling to be monitored, i.e. fishing trawlers.
In very recent years, various companies have equipped / launched satellites that carry a payload capable of detecting AIS transmissions from space! This means that it is now possible to detect most AIS equipped vessels at great range – without the vessel operator being aware.
SeaTraq’s parent company, IMIS Global, have worked closely with these S-AIS data providers. Under agreement, this data can be incorporated into our MariWeb AIS network management software. All the cutting edge data management features and modules that a terrestrial AIS network could benefit from, can now be applied to vessels operating in some of the most remote waters on the planet.
