Abstract

This paper presents an onboard vision/GNSS-integrated fault tolerant navigation system for aircraft final approach. The world-first long-range stereo camera system which captures an object and measures its distance up to 1 km has been developed, and implemented for runway feature detection. The navigation filter is designed based on time-delayed Error State Kalman filter for tightly coupling GNSS pseudo-range measurements with the stereo camera outputs. Then it is augmented with an integrity monitoring function for fault detection and protection level calculation. The whole navigation system has been evaluated on real sensor data sets, acquired on the ONERA experimental UAV, with GNSS fault emulation. The results show an improvement both in fault detectability and in navigation performance thanks to adding the stereo camera to the conventional GNSS navigation setup.
