Abstract: The final presentation of the “Proof-of-Concept of Advanced Navigation Algorithms Based on Factor Graph Optimization”, conducted by OHB Austria and Graz University of Technology within ESA’s NAVISP-EL1-088 project, will present the main developments and results of the activity. The project investigated Factor Graph Optimization (FGO) as an alternative to conventional Kalman-filter-based navigation, considering both standalone GNSS positioning and GNSS/IMU integration. The presentation will outline the design and implementation of the FGO-Nav framework and summarize its validation using dedicated field measurements. Particular emphasis will be placed on the comparative assessment of FGO-based smoothing and EKF-like filtering in terms of positioning accuracy, robustness and computational performance.
