Invited talk at University of Calgary: Integrity-constrained Graph Optimization (October 2024)

Prof. Li-Ta Hsu was invited to give a 60-minute talk — Integrity-constrained Factor Graph Optimization for GNSS Positioning — at the University of Calgary in October 2024. The University of Calgary’s PLAN (Positioning, Location and Navigation) Group is one of the longest-established academic centres for GNSS / inertial navigation research in North America, and a frequent collaborator with PolyU IPNL via co-authored papers (notably with Prof. Naser El-Sheimy’s group on high-accuracy GPS L5 receiver design and super-resolution navigation techniques).

The talk presented the lab’s recent work on integrity-constrained factor graph optimization — extending the FGO framework with statistical integrity bounds appropriate for urban-canyon GNSS positioning under heavy-tailed measurement-error distributions. The underlying research was published in NAVIGATION: Journal of the Institute of Navigation (Xia, Wen, Hsu — 2024).
