The UK’s military technology agency is developing a quantum navigation device aimed at providing GPS-like accuracy for sea vessels without depending on external signals. This initiative addresses the vulnerability of GPS systems to jamming and satellite integrity issues, which could be compromised by events like severe solar flares or antisatellite attacks
Inertial navigation, often used by military operators to supplement GPS, faces challenges due to its reliance on dead reckoning and the potential for drift over time. Quantum navigation, however, offers a more precise solution. Utilizing quantum accelerometers, this technology promises significantly improved accuracy compared to traditional inertial guidance systems.
The concept, initially developed by Imperial College London researchers in 2018, involves a quantum sensor that measures the movements of ultracold atoms in a chamber using laser pulses. This approach has undergone testing aboard the Royal Navy research vessel XV Patrick Blackett in 2023 and the UK defense sealift ship Hurst Point this year.
The UK Ministry of Defence is optimistic about the future of this technology, with Deputy Chief Technology Officer Chester Butterworth highlighting the potential of quantum technologies to address defense challenges and enhance operational capabilities. Further testing is anticipated to advance these novel navigational techniques towards a reliable satellite-free system.
