Ocean Traffic Service
The use of Global Navigation Satellite Systems (GNSS) in the transportation sector has gained huge momentum. GNSS receivers are used in virtually every form of transportation these days. Aircraft, cars, ships and even spacecraft rely on systems such as GPS, Glonass and, in the near future, Galileo to get accurate and reliable information on their whereabouts. However, knowing where you are is only one aspect, you need to be able to communicate where you are to other stakeholders and you need to be aware of the rest of the traffic that might impact your own journey. For personal navigation devices in cars, GNSS receivers are combined with cellular telephone networks and radio broadcasts to obtain additional information on the overall traffic situation and to communicate its own location in case of vehicle tracking.
IDS’ ocean traffic monitoring service combines GNSS receivers with the detection of Automatic Identification System (AIS) broadcasts from ships using space based receivers. Ships transmit their location and heading every few seconds using a special transponder that is mandatory for most ocean going ships. By detecting these signals from space and transmitting this data back to the earth, all vessel equipped with an AIS system can be tracked globally.
