NAVISP-EL1-124-OPTIMISATION OF PVT ENGINES FOR LEO MEASUREMENT DIVERSITY - EXPRO+

This activity focuses on designing and optimizing Position, Velocity, and Time (PVT) engines specifically for LEO-based PNT systems. It aims to exploit the unique measurement diversity offered by LEO satellites, such as multipath whitening, Doppler utilization, and rapid LOS/NLOS transitions. Two approaches will be developed and compared: a conventional Kalman filter-based design and an AI/ML-based design to handle unexpected LEO measurement behaviours. The study will include state-of-the-art review, algorithm development, and benchmarking against traditional MEO GNSS-based engines. Field measurement campaigns will validate performance and inform a roadmap for commercialization. For more info, visit https://navisp.esa.int/opportunity
