【摘要】：为解决全球导航卫星系统(GNSS)姿态测量中整周模糊度的快速求解问题,提出一种基于组合载波相位的短基线整周模糊度解算方法,利用单个历元的观测数据解算整周模糊度.根据多颗卫星的单频载波相位整周模糊度解算结果,应用最小二乘原理对基线向量进行精确求解,进而由基线向量确定出飞行器的姿态角.仿真结果表明,该模糊度解算方法在单个历元内至少能够解算出8颗卫星的载波相位整周模糊度,解决了GNSS动态测姿领域的一个关键性问题.测姿结果显示,偏航角和俯仰角的测量误差均小于0.2°.该研究成果可以为GNSS姿态测量系统在航空、航天等对实时性要求较高的领域中的应用创造条件.
[Abstract]:In order to solve the problem of fast resolution of integer ambiguity in GNSS attitude determination, a short baseline integer ambiguity resolution method based on combined carrier phase is proposed. The integer ambiguity is solved by using the observation data of a single epoch. Based on the results of integer ambiguity resolution of single frequency carrier phase of multiple satellites, the baseline vector is solved accurately by using the least square principle, and then the attitude angle of the aircraft is determined from the baseline vector. The simulation results show that the ambiguity resolution method can solve the integer ambiguity of the carrier phase of at least 8 satellites in a single epoch and solve a key problem in the field of GNSS dynamic attitude determination. The results of attitude determination show that the errors of yaw angle and pitch angle are less than 0.2 掳. The research results can create conditions for the application of GNSS attitude determination system in aeronautics and spaceflight.
