摘要
多路径是高精度GPS变形监测的主要误差来源。本文在推导信号反射预计公式的基础上,提出了一种削弱GPS多路径误差影响的附加参数法。试验表明该方法能有效减弱GPS相位多路径误差的影响。
Multi-path(MP) is the main error source for high precision deformation monitoring using GPS. After deriving the formulas of reflection-predicting we mitigate multi-path by combing reflection-predicting with parameter-estimator in this paper. One test shows that the proposed method can mitigate multi-path efficiently.
