GPS网络RTK线性组合法与内插法关系的讨论

RELATIONS BETWEEN INTERPOLATION METHOD AND LINEAR COMBINATION METHOD FOR GPS NETWORK RTK

证明了线性组合法可以转化为内插法在平面的线性函数内插 ,得出了采用线性函数内插法模型在理论上也能直接消除卫星轨道误差项和电离层延迟项对动态用户的影响 ,并且还能大幅度削弱对流层延迟。

This paper introduces the interpolation method and linear combination method for GPS-network RTK, and then proves that the linear combination method can be transformed into the interpolation method. Thus, it draws a conclusion that the orbit bias and ionospheric delay of the rover receivers can be eliminated, and that the tropsphereic delay, multipath as well as observation noise of the rover receivers can also be mitigated by using the interpolation method .
