A robust INS/PnP fusion method for GNSS-denied navigation of small UAVs
… filters used to mechanize camera-aided inertial navigation systems (INS) while preserving the estimation accuracy. This third approach is a hybrid filter that can switch between the optimal tight and suboptimal loose strate- gies "on the fly" depending on the geometry of the landmarks being …

Vision-Based Aerial Navigation Using Satellite Offline Maps
While Global Navigation Satellite System (GNSS) technology combined with advanced augmentation techniques provides high accuracy, its reliance on signal integrity leaves safety-critical applications vulnerable to spoofing and jamming. To address this, a lightweight vision-based localization module …

Evaluating UAV Visual-Inertial Odometry Trajectory Error and Feature-Level Metrics over Repetitive Floor Patterns
… technique for Uncrewed Aerial Vehicle (UAV) navigation in environments where Global Navigation Satellite System (GNSS) signals are unavailable. VIO systems that rely on visual feature tracking are susceptible to performance degradation when operating over surfaces containing repetitive visual …
