摘要: 根据北斗双星定位系统(简称双星定位)的特点,提出了北斗双星与SINS组合的最优预测模型。为了验证该滤波方法对状态估计的一致性,研究了滤波器一致性的准则,并给出了检验的统计量。试验证明,本文提出的滤波器与系统是匹配的。

Abstract: According to the characteristic of Beidou double-star positing system(double-star positoin),this paper puts forward the optimal predication model of double-star position/SINS integrated system.In order to validate the consistency of the filter,this paper also studies the criteria for consistency of a filter,and gives the tested statistic.The experiment based on practical measured data shows that the filtering method is consistent with the integrated system.
