摘要
结合实际数据,分析基准站双差电离层延迟与基线长度和时间的关系,并对各种内插算法进行比较。比较结果认为,LIM法的内插效果最好,基线长度小于100km时,内插精度优于3cm。
The interpolation methods about the GPS RTK networks are firstly described, then from the GPS observations in GPS RTK network, the relations of double-differenced inonospheric delay with the baseline length and time are analyzed and compared with each other. The results show that the best interpolation method is LIM,its accuracy is higher than 3cm if the baselines are less than 100 km.
