AIS space receivers

An AIS receiver in a satellite will extend the range considerably and make it easier to monitor ship traffic and fishing in the High North. The altitude of the satellite gives the AIS receiver a long range and the satellite can therefore make observations over large sea areas. The signals are strong enough to be received by a satellite in low Earth orbit.

Innovative technology

Kongsberg was one of the early small sat pioneers and already in 2010 the company has its first AIS space based receivers in orbit. In tight collaboration with Forsvarets Forskninsinstitutt (FFI), Norwegian Space Agency (NOSA) and European Space Agency (ESA), Kongsberg has continuously improved our AIS technology and we have a range of innovative AIS space-based payloads. Highest decoder performance, multi-antenna support, low power, miniaturized housing, large mass memory, solid lifetime and failure free heritage are some of the features. Though innovative technology we achieve leading end-to-end performance, where the superior sensitivity and algorithms of the ASRs makes the receivers capable of detecting even AIS class B vessels. Reconfigurable software-defined radio (SDR) technology is used, enabling support for future enhancements in algorithms or changes in AIS/VDES standards.

Vessel detection performance to the next level

Kongsberg started working with AIS twenty years ago and is the AIS equipment manufacturer with the broadest experience. The two latest products, ASR c50 and x50, are Kongsberg’s 4th generation AIS Space Receivers and builds on this foundation of expertise. A multiple set of decollision algorithms is optimised for best possible vessel detection in high-density and medium-density areas. Our ASRs will give the end user a giant leap in vessel detection compared with existing SAT-AIS receivers.

    What is AIS

    AIS is a short range coastal traffic system used by ships and Vessel Traffic Services around the world. AIS is required to be fitted on every seagoing vessel of 300 gross tons or more. Its purpose is to help ship crews to avoid collision with other vessels as well as to allow maritime authorities to track and monitor ship movements. Today's AIS allows ships to communicate with other ships and land based base stations through VHF signals. This means that it is not possible to communicate outside the field of vision.

    Services and support

    • 24/7 Technical support

      Our 24/7 technical support team is there to help at any time, day or night, wherever your vessel is.

    • Conversions, retrofit and refit

      We understand the importance of having the right parts, available in the right place, at the right time.

    • Training

      Ensure that your crew is properly and thoroughly trained. This will reduce operational risk, downtime and maximise return on asset investment.
