Abstract

Abstract: A single integrated navigation system cannot meet the long-endurance high precision requirement of space long-range missile, so a SINS/GPS/CNS multi-integrated navigation system in launch inertial coordinate system was designed. Firstly, an integrated navigation model was built in the launch inertial coordinate system. Secondly, a SINS/GPS/CNS integrated navigation algorithm based on the federal Kalman filter was designed. Finally, an integrated navigation algorithm verification prototype based on PC104 was developed. Through the real time semi-physical simulation tests, the attitude error of triple integrated navigation system is below 15″, the position error is below 10m and the velocity error is below 0.2m/s. It indicates that the integrated navigation system algorithm designed is right and the realization of the system is reasonable.
