摘要
提出了在相位平滑伪距差分的基础上求解RTK的整周模糊度,利用GPS和GLONASS的组合来增加求解整周模糊度的载频冗余度。在单差方程向双差方程的变换中,以Householder变换代替传统的法线方程法来保证双差方程中观测量的不相关,最终采用LAMBDA算法求解出整周模糊度。数值分析结果表明:该方法可以提高整周模糊度的求解速度和求解结果的稳定性,因此适用于动态RTK技术。
Based on Phase Smoothed Differential Pseudo-range, the integral ambiguity of RTK is solved. In order to increase the carrier frequency redundancy, the satellites of GPS and GLONASS are combined during carrier phase measurement. To ensure the measurements in the double difference equation are unrelated, the Householder transformation is used instead of the normal equation method, and the integral ambiguity is eventually solved by the LAMBDA algorism. The numerical analysis result demonstrates that, by using this method, the integral ambiguity can be solved effectively, and the solution of the integral ambiguity is more stable. Therefore, it does work in the dynamic RTK technology.
