A Data Fusion Method of Multi-Sources Measurement Data Based on Federated UKF Filter

摘要：

　　To ensure the tracking reliability and accuracy,and to increase the utilizing efficiency of measurement data in space flight tracking,a data fusion method in real-time orbit tracking based on federated UKF filter is put forward.The key technology of the multi-source measurement data fusion scheme is also analyzed in this paper.The computer simulation shows that the reliability of the real-time orbit tracking can be increased remarkably and the tracking accuracy can be increased by thirty percent.In this method,the fused ballistic curve is con-tinuous and the convergence can meet the requirement of real-time guidance,which has great meanings on the overall level of spaceflight commending and controlling system.
