Yufeng Chen, Zeyun Yang, Jizhang Zuo, Guoding Wang · 2007
For the region passive locating system named Beidou, which nowadays is under extensive research, this article puts forward a proved algorithm by using Kalman filter to reject dynamic fault tolerant. This method upgrades the tracing ability of the filter under the airborne environment. The real-time character is improved because of the decrease in the dimension numbers of the state equation. Verified from the trying out data, the locating precision of the system can reach up to 92 meters, filtered by the algorithm. Thus it can meet the general needs of the users in the air.
