Filter Method and Its Consistency of Double-Star Position/SINS Integrated System

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.
