摘要
导航卫星载体姿态测量是航空、航天、航海和陆地导航中的关键技术.在基于载波相位差的载体姿态测量中,相位双差整周模糊度的求解是重点和难点.该文将进化算法应用于整周模糊度的搜索,无需进行模糊度的去相关处理,采用进化算法直接搜索整周模糊度,进而求解出基线矢量,获得载体姿态.该方法可以提高整周模糊度求解的效率和实时性,适用于动态载体姿态测量.对比实验结果证明了该方法的有效性.
Attitude determination based on navigation satellites is a key technology in aviation,marine and land navigation. In the method using carrier phase difference,the solving of double difference integer ambiguity is important and difficult. This paper adopts Evolving Algorithm to search for the optimal integer ambiguity directly without the decorrelation of ambiguity,and calculates the baseline vector consequently. This method can improve the efficiency and real-time performance of integer ambiguity solving,so as to be applied in dynamic attitude determination. The experimental results show the validity of this method.
