摘要
在Sage-Husa滤波基础上,提出了其改进的滤波算法,以解决它在容错性能差和高阶状态阵滤波发散等方面的问题。仿真结果表明,利用改进Sage-Husa滤波可有效提高GPS/INS组合制导的容错性能和精度。
Based on the analysis of the Sage-Husa filter, a new improved Sage-Husa filter is given to apply in the GPS/INS integrated system. The simulation shows that the computing capability and fault-tolerant performance of the new Sage-Husa filter is superior to that of the original Sage-Husa filter when used in GPS/INS integrated navigation.
