The UK has successfully tested quantum-based navigation systems in flight. This commercial trial, led by the quantum technology firm Infleqtion, aims to enhance resilience against GPS jamming and spoofing.
Although GPS jamming typically does not affect an aircraft’s flight path, Quantum-based Positioning, Navigation, and Timing (PNT) systems aim to provide accurate and resilient navigation, complementing existing satellite systems, and ensuring uninterrupted operations for global air traffic.
Infleqtion, in collaboration with aerospace companies BAE Systems and QinetiQ, conducted the trials at MoD Boscombe Down in Wiltshire. Science Minister Andrew Griffith participated in the final test flight on May 9. The project has received nearly £8 million in government funding as part of the National Quantum Strategy, which seeks to establish the UK as a leader in quantum technology.
The test flights showcased two key quantum technologies: the compact Tiqker optical atomic clock and an ultra-cold-atom-based quantum system, both tested aboard QinetiQ’s RJ100 Airborne Technology Demonstrator. These technologies are part of the development of a Quantum Inertial Navigation System (Q-INS), which aims to provide precise and resilient navigation independent of traditional GPS.
Dr. Timothy Ballance, President of Infleqtion UK, highlighted the importance of these trials: “Our recent trials mark a significant step forward in the development of quantum PNT solutions. The work we have done directly addresses the critical need to reduce our reliance on satellite navigation systems, which are vulnerable to various risks.”
The project involved extensive collaboration among industry and academic partners, including the Fraunhofer Centre for Applied Photonics, Alter Technology UK, Caledonian Photonics, Redwave Labs, PA Consulting, BAE Systems, and QinetiQ. Supported by UK Research and Innovation (UKRI), these efforts aim to address the UK’s reliance on GNSS/GPS for critical applications.
