Oral presentation at ION Pacific PNT 2026, Honolulu

I presented Federated Extended Kalman Filter Integrating Terrain-Referenced and Quantum Magnetometer-Aided Navigation for GNSS-Denied Environments at the ION Pacific PNT 2026 meeting in Honolulu, Hawaii. The talk addressed the dead zone of quantum magnetometers, one of the main practical challenges in magnetic-anomaly navigation, and how a federated filter with terrain-referenced navigation keeps the solution available.
