“Robust” GNSS receiver provides platform to access Galileo PRS

July 14, 2015 // By Graham Prophet
QinetiQ (Farnborough, UK) has developed a robust navigation receiver which will utilise the new global navigation satellite system (GNSS) Galileo, and particularly the secured Public Regulated Service (PRS).

QinetiQ has built a high performance, next generation GNSS receiver which will incorporate signals from the new Galileo system (the European equivalent of GPS). The new receiver is multi-constellation and multi-frequency and is designed to process encrypted signals from the Galileo PRS service as well as open services such as GPS.

(PRS is a secure, encrypted, interference-resistant level of service available from Galileo that is restricted to users authorised at government level.)

The receiver is, the R&D company says, a significant step towards developing an end-user product for navigation, tracking and timing. It will offer highly secure, accurate and reliable position, velocity and timing intended for users with a mission-critical need such as governments, the military and emergency services across Europe.

Dr Nigel Davies, head of QinetiQ’s Secured Navigation Group, said: “We are delighted that, after years of QinetiQ R&D and collaboration with the EU, European Space Agency (ESA) and UK government, we have achieved this major step towards our goal of offering robust navigation products using Galileo. It is a significant breakthrough for us to have built a fully operational receiver on a platform which proves our product architecture, functionality, and algorithms.

“Our next step will be working to refine the product family and preparing it to be brought to market, which includes developing additional features and reducing its size to that of a postage stamp, in a form factor similar to our existing, highly successful, Q20 receiver. We have full confidence in this product and are proud to be at the forefront of this exciting new phase in European navigation.”

The prototype receiver is a multi-constellation, multi-frequency, all-in-view receiver which can receive and process the Galileo PRS as well as Galileo Open Service and GPS Standard Positioning Service. It is also designed to utilise other GNSS signals including the Russian GLONASS and Chinese Beidou systems as well as space-based augmentation services (SBAS) such as WAAS and EGNOS. The
