Application of fault tolerant algorithm in bionic polarization integrated navigation system

摘要

In this paper, a real-time fault tolerant scheme based on the bionic polarization integrated navigation system is proposed. First, we use the polarized light information to assist SINS/GPS/geomagnetic integrated navigation system, realize the redundancy of the heading information and improve the reliability of the system. Then, Kalman filter based real-time fault detection program is used to detect whether the system fails. Once the failure occurs, fault isolation and system reconfiguration are applied automatically. Finally, the proposed method is tested in the bionic polarization integrated navigation system.
