Trial speeds up next generation of atomic clocks

Land February 23, 2026

The Defence Science and Technology Laboratory (Dstl) has successfully concluded a trial focused on the development of next-generation atomic clock technology, a critical component in the UK’s strategy to establish resilient Position, Navigation, and Timing (PNT) capabilities.

The initiative addresses the increasing vulnerability of satellite-based systems, such as GPS, which are susceptible to jamming and spoofing in contested environments. By developing sovereign atomic clock technology, the Ministry of Defence (MoD) aims to provide UK forces with precise and persistent timing data across all terrains and climates, ensuring operational continuity when global navigation satellite systems are denied.

For businesses within the UK defence supply chain, the trial represents a significant step toward the commercialisation of quantum-sensing technologies. Unlike laboratory-based testing, Dstl’s trial involved long-term, unattended operation of the devices, providing a realistic assessment of how this hardware performs under military conditions. This methodology allows manufacturers to refine individual components and entire systems against robust military standards. The collaboration model utilised by Dstl also highlights opportunities for Small and Medium Enterprises (SMEs) to access specialist test and measurement expertise that may not be available in-house. A notable participant in the trial, Far Field Exploits, an SME specialising in wireless time and frequency transfer systems, utilised Dstl’s high-end equipment and technical oversight to validate its hardware, demonstrating a clear pathway for smaller firms to integrate into major MoD research programmes.

The Royal Navy has identified these advancements as essential for the future of both crewed and uncrewed maritime operations. Precise PNT data is a prerequisite for safe underwater navigation, where satellite signals cannot penetrate. Commander Matt Steele of the Royal Navy’s Office of the Chief Technical Officer emphasised that the insights gained from these trials position the UK to lead the global market in quantum-enabled navigation. This development is expected to open new export opportunities for the UK defence industrial base as allied nations seek similar resilient timing solutions.

The government has outlined a clear roadmap for the deployment of these technologies, with a subsequent trial scheduled for 2027. This next phase will expand the scope beyond atomic clocks to address broader military challenges in quantum navigation. The MoD’s stated goal is to achieve the deployment of quantum navigation systems, including these next-generation clocks, on aircraft by 2030. For professionals in the sector, these milestones provide a structured timeline for investment and innovation, ensuring that the UK remains at the forefront of high-accuracy PNT technology for the next decade.
