AIS space receiver

ASR x50 is the 4th generation SAT-AIS receiver from Kongsberg and part of the new eXtended lifetime product series. The receiver is a reconfigurable SDR based receiver, designed to support simultaneous onboard AIS decoding and digital sampling. ASR x50 has, through new enhanced algorithms, multi-antenna support and superior dynamic range, leading end-to-end performance. It is designed for a 7+ year lifetime and takes vessel detection via AIS to the next level.

Innovative technology

This generation SAT-AIS receiver from Kongsberg is the latest achievement of years of continuous innovations. Highest decoder performance, multi-antenna support, built-in redundancy, low power, miniaturized housing, large mass memory and improved lifetime. The end-to-end performance exceeds existing SAT-AIS receivers, where the superior sensitivity of the ASR x50 makes the receiver 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. ASR x50 is Kongsberg’s 4th generation AIS Space Receiver 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. ASR x50 will give the
end user a giant leap in vessel detection compared with existing SAT-AIS receivers.

Space grade using latest technologies

The eXtended lifetime series from Kongsberg is designed for a lifetime of 7 + years in LEO.

ASR x50 uses the latest generation EEE parts from best-inclass manufacturers. This enables Kongsberg to design for leading capabilities at low power and miniature size. All EEE parts have been carefully selected and extensively tested. Active components have been subject to heavy ion, proton and Co60 test campaigns to ensure radiation tolerant design. The failure rate at 40 °C (±5 °C) is less than 800 and the availability is 99.99 % over the lifetime.

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
