Outlier-Aware LiDAR–IMU–UWB Integration With NLOS Mitigation and Anchor Self-Calibration in Complex Scenarios

LiDAR–inertial odometry (LIO) is susceptible to long-term drift in global navigation satellite system (GNSS)-challenged environments, limiting accurate state estimation for unmanned aerial vehicles (UAVs), mobile robots, and autonomous ground vehicles. Ultrawideband (UWB) infrastructure can provide ranging constraints...

Incremental-Smoothing-Based ARAIM Protection Levels for Tightly Coupled GNSS/IMU Integration in Urban Canyons

Protection levels (PLs) bound position errors under specified fault hypotheses and risk budgets, but advanced receiver autonomous integrity monitoring (ARAIM) is formulated for snapshot GNSS estimation rather than the correlated posterior of tightly coupled GNSS/IMU factor graph optimization (FGO). This paper formulate...
