The International Civil Aviation Organisation (ICAO) is currently working on the next iteration of Ground Based Augmentation System (GBAS) enabling CAT II/III approaches, GBAS Approach Service Type (GAST) E, supporting Dual Frequency Multi-Constellation (DFMC) GBAS. This concept will make GBAS more resilient to ionospheric activity and radio frequency interference (RFI), improve overall… -
Start date: 18/02/2026Duration: 15 MonthsUPDATE phase 2 will develop an MVP of a UK National PNT Digital Twin. The digital twin will provide “quasi-realistic model” of PNT services services across the UK (including GNSS, ELORAN and the NTC), informed by service status data, that looks, operates and behaves comparably to actual PNT services throughout the UK. The outcome of the project will be an open and modular PNT DT architecture…Subcontractors

The GOACE (Ground Optical Atomic Clock for Evaluation) project aims to deliver an optical atomic clock for evaluation by the European Space Agency. Developed by Rolex Quantum and CSEM, the clock employs an optical transition in Rubidium to achieve outstanding long‐term frequency stability with competitive SWaP, and low‐maintenance. The clock will undergo a full year of continuous testing at…Subcontractors

Start date: 16/02/2026Duration: 26 MonthsThe proposed project named Multi-Frequency Alternative Position, Navigation and Timing (MF-APNT), will analyse, design, construct, demonstrate, measure and evaluate a new approach for distributing Position, Navigation and Timing (PNT) signals. The system concept is based on adding spread spectrum signals onto broadcasting and communication channels, hopping between frequency bands, and by doing so… -
Start date: 16/02/2026Duration: 24 MonthsPNT satellite systems (i.e. GNSS) have become an integral part of contemporary society and economy. However, increasing reliance on continuous PNT availability raises concerns related to service disruptions, hardware failures, intentional jamming or spoofing, and operations in GNSS-denied environments. The Muometric Positioning System (MuPS) uses galactic cosmic rays to enable positioning where…Prime contractor

Start date: 15/02/2026Duration: 22 MonthsThe main objective of this project is to design, develop, and validate a prototype ultra-large synthetic aperture array (ULSA) GNSS receiver for automotive applications, both hardware and software, based on a moving array antenna. While there is a lot of prior art on GNSS antenna array techniques, and some on extending a single GNSS antenna into a synthetic array, there are no documented real-life… -
Start date: 12/02/2026Duration: 18 MonthsThe aim of the project is to demonstrate selected time and frequency transfer (UTC) techniques based on fibre optic networks. The implementation of such techniques, complementary to GNSS, is crucial to ensure the proper functioning of both the Critical National Infrastructure (CNI) and the various sectors of the economy. The project involves demonstrating two alternative scenarios for…Prime contractor
