2021/05/20 The QinetiQ PRS receiver. QinetiQ today announced a major breakthrough in developing a robust navigation receiver that will use the Galileo, Europe’s satellite navigation system — in particular, the secured Public Regulated Service (PRS). QinetiQ’s new high-performance, next-generation GNSS 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. Qinetiq introduced the receiver today at the UK Space Conference, being held July 13-15 in Liverpool. The receiver — now a in prototype form — is a significant step towards developing an end-user product for navigation, tracking and timing, QinetiQ said. 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.  “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,” said Nigel Davies, head of QinetiQ’s Secured Navigation Group. “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,” Davies said. “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 that can receive and process the Galileo PRS as well as Galileo Open Service and GPS Standard Positioning Service. It is also designed to utilize 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 receiver, which is based on the military standard SEM-E form factor, is also designed for integration into multi-sensor navigation systems and is designed to provide high levels of protection against jamming and spoofing.  It has a fast acquisition capability and is designed for government security accreditation. It is expected that a suite of robust products will be ready by 2020 to coincide with the completion of the Galileo project, which will be the world’s third GNSS to be completed after the United States and Russian systems. The new receiver is part of a long pedigree in robust GNSS receivers. Q20 was QinetiQ’s first GPS receiver, designed for specific challenging applications: high dynamics, or high sensitivity like tracking from inside a shipping container. QinetiQ’s family of receivers will include two new products based on the new receiver. Q40 will be QinetiQ’s next-generation robust open service receiver, which will be a multi‑constellation, multi‑frequency open-service receiver which can use signals from all of the GNSS open services. Q50 will incorporate all of the functionality of the Q40 receiver, but also offer Galileo PRS for authorized users who need the additional capabilities and robustness. “The device we have built is a major stepping stone to Q40 and Q50 as the technology has all been built for the receiver products and is designed to be shrunk on to a single ASIC microchip,” Davies said. “Our focus of attention will now be to turn what we have built into an ASIC product which is ready for market.”
