摘要
本文描述了局域差分系统的基本原理,分别给出并实现了差分系统中地面系统和用户系统的载波平滑码伪距方法,通过实验分析,无载波平滑算法时定位误差的方差为0.52m,而有载波平滑算法时定位误差的方差仅为0.13m,定位精度提高了75%。
The paper described the basic principles of local differential system, then given and implemented carrier smoothed code pseudo in local differential system. From the method by experimental analysis, the positioning error variance of no carrier smoothing algorithm is 0.52m, while the positioning error variance of carrier smoothing algorithm is only 0.13m, the positioning accuracy is improved by 75%.
