Random Weighting Estimation of White Noise Error Characteristic in Integrated INS/GPS/SAR System

Random weighting estimation is an emergent algorithmic method in statistic, which is firstly applied to the research of navigation system in this paper. An algorithm is presented for on-line random weighting estimating the white noise errors of integrated INS/GPS/SAR navigation system. Secondly, The Random weighting estimation is presented in terms of variance and drift rate parameters, and the method applied to estimate the white noise errors of INS/GPS/SAR navigation system is proved to be effective. Research result shows that the random weighting estimation has a better performance than other statistic estimation methods.
