New adaptive Kalman filter boosts UAV state estimation during outages

Researchers have developed a new adaptive Kalman filter, the N-Deep Recurrent Sage-Husa Filter (NDR-SHKF), designed to improve state estimation for Unmanned Aerial Vehicles (UAVs). This advanced filter replaces the static forgetting factor of traditional methods with a learned memory attenuation policy managed by a hierarchical recurrent network. The NDR-SHKF's architecture distinguishes between short-term sensor anomalies and long-term dynamic trends, enabling more robust performance during telemetry outages and varying noise conditions. Evaluations on simulated chaotic attractors and real-world UAV flight data show it outperforms existing adaptive estimators and data-driven approaches. AI

    Learned Memory Attenuation in Sage-Husa Kalman Filters for Robust UAV State Estimation

    Unmanned Aerial Vehicles in dynamic environments face telemetry outages, structural vibrations, and regime-dependent noise that invalidate the stationary covariance assumptions of classical Kalman filters. The Sage-Husa Kalman Filter (SHKF) estimates noise statistics online, but …
