载波相位平滑的主要目的就是使用精度高的载波相位测量值作为辅助信息, 以使码测量值上的大的随机误差得以平均,从而提高伪距观测定位精度。文章介绍了3种 载波相位平滑伪距的模型,并对这3种平滑方法进行了仿真分析,得出平滑算法的精度与接 收机性能、权重因子和平滑递归的次数有关。
English Description：
The main purpose of the carrier phase smoothing is to use high precision of carrier phase measurements as auxiliary information, _ to make code measurements on the big random error of the average, and pseudorange observation location accuracy is improved.This article introduces three kinds of carrier phase smoothing pseudorange _ model, and the three kinds of smoothing method has carried on the simulation analysis, it is concluded that the precision of the smoothing algorithm with _ receiver performance, weighting factor and smooth the number of recursion.
