一种基于GPS单差模型的姿态解算算法

针对采用双差模型无法克服双差观测量的强相关性这一问题,以观测量不相关的单差模型为基础,提出一种可递归处理的定姿算法.该方法用码观测量辅助载波相位观测值,增加了信息量,通过递归估计模糊度浮点解及其方差协方差矩阵,从而可以利用LAMBDA算法估计整周模糊度.该算法计算量较小,且具有数值稳定性.实验结果表明,该算法的初始化时...

An attitude determination algorithm based on GPS single-differenced mode

It is difficult to overcome the high correlation of double differential observation using double-differenced model and the initialization procedure costs a long time with makes it difficult to apply in practice.To deal this problem,a recursive algorithm based on the single-differenced model is presented in which the observations are not correlated.The new method increases observation information with the aid of code for original carrier phase observation.At the same time the float ambiguity solutions and it...
