摘要:
频率不同,波长也不同,两种载波的相位差随着传播路径的不同而变化 .根据两种载波相位观测值,可求整周模糊度 .此模糊度解也具有多值性 .通过C/A码伪距观测值提供约束,缩小模糊度解的空间 .最后,采用最小二乘平差和RATIO检验获得整周模糊度的惟一解
Abstract:
The charaeteristic of two kinds of carriers is analysed. They are different in frequency, so also in wavelength. Their phase difference changes with the difference of propagath path. Therefore, the integer ambiguity of carrier phase can be resolved according to observed value of two kinds of carrier phase. This ambiguity resolution is multiple-valued. With the constraint offering by observed value of C/A code range measure, the space of ambiguity is reduced. The unique resolution of integer ambiguity is finally obtained by adopting least square error and RATIO test.
