GNSS technologies typically suffer significant accuracy issues in urban environments due to signal degradation caused by obstacles like buildings which block and reflects GNSS signals leading to big positioning errors. The most dangerous impairments are due to specularly reflected Non-Line-Of-Sight (srNLOS) signals. Such errors can be attenuated through the application of the Intelligent Urban…

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…

ESA's NAVISP-EL1-077 project aims to develop a prototype Position, Navigation, and Timing (PNT) system, focusing on secure positioning through GNSS and 5G encrypted signals. The initiative includes creating two emulators: a User Terminal Emulator (UTE) and a Service Provider Emulator (SPE). Qascom and the consortium have two main objectives: developing a testbed and a prototype User Terminal.…

This activity will demonstrate a fiber-optic technique for high-precision time and frequency transfer as a robust complement to GNSS, enabling UTC distribution across geographically separated and even transnational sites. Building on Cycle’s long-standing expertise in stabilized RF transfer over short-range fiber-optic links, the work will advance this capability to long-haul distances exceeding…

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…

There 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…
