摘要
快速准确地确定整周模糊度是进行高精度GPS测量的关键问题。根据阳山金矿控制测量的自身特点,对刘宁等人提出的新GPS整周模糊度单历元求解法进行改进,简化模糊度搜索空间,增加单频机采集数据的算法,通过线性组合逆变化求取模糊度,以模糊度函数法进行真值的搜索,实现单历元解算。在阳山矿区GPS控制测量中随机选取两条基线进行解算,从而证明此法的可行性和可靠性。
Quickly and accurately determine the integer ambiguity is a key issue carried out high-precision GPS measurements. The authors measured according to the Yangshan gold mine to control its own characteristics, the new GPS Ning et al proposed integer ambi- guity single epoch solving method to improve and simplify the search space of ambiguity, sin- gle-frequency machine algorithms to increase data collection through linear combination of in- verse variation strike ambiguity to ambiguity function method to search the true value of sin- gle-epoch solver. In Yangshan mine GPS control survey randomly selected two baseline sol- ver, thus proving the feasibility and reliability of this method.
