摘要
探讨了一种GPS载波相位整周模糊度的快速求解方法,分析了搜索空间中的独立变量,推导出了新的传递矩阵。该矩阵将所有的测量残差直接和最小求解搜索空间相关联,通过仅选择那些与卫星几何尺寸和测量残差一致的模糊度的组合,搜索空间被最小化。仿真结果表明,与目前最常用的搜索方法-LAM BDA方法相比,提出的快速求解方法可以改善计算效率,缩短模糊度求解时间。
This paper discusses a fast calculation method of GPS carrier phase integer ambiguity resolution, analyze independent variables in search space, derivate new residual transition matrix which directly associates all measurement error with minimum search space, and search space is minimized through selecting the ambiguity combination which is consistent with satellite geometry size and measurement error. The simulation show this fast calculation method can acquir.e better computation efficiency and shorter calculation time, compared with common LAMBDA method.
