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…

Factor graphs are widely used in robotics, especially for simultaneous localization and mapping, but also in filtering and smoothing, model-based signal processing, artificial intelligence, coding and decoding. They serve as probabilistic models where variable nodes are associated with system states, and factors are associated with measurements. The factor graphs techniques have been applied 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.…

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…

Maritime shipping has embraced GNSS to improve safety and efficiency, but the availability and reliability of such systems have in recent years declined. The Maritime Alternative PNT Solution (MAPS) activity aims to demonstrate an Alternative PNT (APNT) solution based on the maritime VHF Data Exchange System (VDES) and the maritime Medium Frequency R-Mode service. The ambition in phase 1 of…
