On-line Random Weighted Estimate of White Noise Errors in Integrated INS/GPS/SAR System
Sicong Ren · Journal of Chinese Inertial Technology · 2000
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.
