Abstract: The difference of platform angles error and attitude error are analysed,and the(conversion) matrix is gained.To take the application into account,the observations vector(pretreatment) instead of complicated attitude observation equation is used,to improve the attitude integrated algorithm.Then the system eliminates the math former errors,and realized very easy.The plentiful simulations results show that the improved attitude integrated algorithm can enhance the precision validly,
