This paper addresses the issues of unmanned aerial vehicle (UAV) indoor navigation, specifically in areas where GPS and magnetometer sensor measurements are unavailable or unreliable. The proposed solution is to use an error state extended Kalman filter (ES -EKF) in the context of multi-sensor fusion. Its implementation is adapted to fuse measurements from multiple sensor sources and the state model is extended to account for sensor drift and possible calibration inaccuracies. Experimental validation is performed by fusing inertial measurement unit (IMU) data obtained from the PixHawk 2.1 flight controller with pose measurements from light detection and ranging (LiDAR) Cartographer SLAM, visual odometry provided by the Intel T265 camera and position measurements from the Pozyx ultra-wideband (UWB) indoor positioning system. The estimated odometry from ES-EKF is validated against ground truth data from the Optitrack motion capture system and its use in a position control loop to stabilize the UAV is demonstrated.
