Quantum sensing using Rydberg atoms offers a potential route to wide bandwidth, small, all optical reception of electromagnetic signals. The sensor is based on optical pumping of alkali metal vapour to a level which is resonant with incoming EM radiation; this impacts the optical transmittance of the vapour allowing optical readout of modulated signals. This work will assess the potential to use… -
The work proposed focuses on developing AI-based anomaly detection software to detect anomalous signals from quantum sensors used within PNT applications. Infleqtion have been developing a novel approach to AI called “Contextual Machine Learning” which is inspired by quantum contextuality and has been shown to perform particularly well in settings where context can improve the AI model’s…Prime contractor

This activity delivers a proof of concept towards the development of a Position, Navigation, and Timing capability that benefits from the unique simultaneous multilink capability of the ALL.SPACE SATCOM terminal. The terminal will analyse signals of opportunity from available Ka-band satellites in GEO, MEO and (potentially) LEO orbits to estimate its position and orientation in a GNSS-denied…Subcontractors

Various 5G terrestrial positioning techniques have been studied and demonstrated by the 3GPP, so positioning accuracy and availability with 5G terrestrial networks is a well- established concept and several positioning methods are defined in 3GPP; however, position integrity with 5G private networks seams largely un-investigated. If 5G is to be used for reliable positioning, then further…Prime contractor

Spirent is aiming to develop and provide a test framework for PNT resiliency testing for users, operators, and providers of Critical National Infrastructure (CNI). The proposed framework will consist of the Spirent PNT Alliance, the Spirent Shopfront and the Resilient PNT Assessment Scheme, and will provide support to each of the ten points of the UK government’s Resilient PNT strategy [17], by…Prime contractor

Start date: 17/06/2025Duration: 24 MonthsThere is increasing worldwide dependency on global navigation satellite systems (GNSS) that deliver uninterrupted timing signals. This GNSS dependency is driving novel holdover clock development to flywheel over periods when the GNSS signal is unavailable. Enhanced GNSS with next-generation optical clock technologies could facilitate both significantly reduced positioning errors and improved…Prime contractor

Zero Point Motion is taking a new approach to the design of micro-electro-mechanical (MEMS) inertial sensors by enhancing MEMS with light. Using our patented photonics-based optomechanical detection method, our sensors can be 10-100x higher performance than low cost capacitive MEMS devices. We're positioned to leverage the boom of silicon photonics in the semiconductor supply chain, and the proven…Prime contractor

Start date: 01/05/2025Duration: 15 MonthsTOUCAN will complement efforts to reestablish a UK Enhanced Long-Range Navigation (eLoran) system, which will serve as a terrestrial backup to satellite-based services. A critical goal is to ensure that this system operates independently of the more vulnerable Global Navigation Satellite Systems (GNSS). The project’s primary objective is to establish an accurate, independently verifiable TWSTFT…Subcontractors

Optical clocks are at the core of alternative positioning, navigation, and timing (alt-PNT) solutions that do not depend on Global Navigation Satellite System (GNSS). When fully realised, alt-PNT will increase the resilience of Critical National Infrastructures (such as the UK National Timing Centre) and provide many sectors of the economy with increased commercial returns. OPTiK aims to increase…Prime contractor
