Tenders are invited for NAVISP-EL1-124-OPTIMISATION OF PVT ENGINES FOR LEO MEASUREMENT DIVERSITY - EXPRO+ NAVISP-EL1-124-OPTIMISATION OF PVT ENGINES FOR LEO MEASUREMENT DIVERSITY - EXPRO+ Tender Action Number: 1-13542 Activity Number: 1000046482 Clarification Request Deadline 11/08/2026 13:00 CET Closing Date Extension Request Deadline 11/08/2026 13:00 CET Announcement Date 18/05/2026 Last Update On 06/07/2026 15:22 CET Update Reason Tender Action Issued 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.
