摘　　要：首次把随机加权估计这一新兴的统计计算方法应用于导航系统的研究 ,证明用它进行INS/GPS/SAR组合系统误差特性的估计是可行的 ,仿真实验和计算结果表明 。Random weighted estimate is a novel statistic computation method,which is firstly applied to the research of navigation system in this paper.An algorithm is presented for online random weighted estimating the white noise errors of integrated INS/GPS/SAR navigation system without reference system .The random weighted estimate is presented in terms of variance and drift rate parameters.This method is applicable for estimating the white noise errors of integrated INS/GPS/SAR navigation system,and its applicability is proved.The random weighted estimate is superior to other statistic estimate methods,which is shown by simulation results.
