| 摘 要： | 针对不同对流层映射函数对CORS站数据解算的影响,为获知适用于我国东北部地区的对流层延迟解算策略,就CORS站数据解算中所使用的对流层映射函数进行比较分析。结论:随着卫星高度截止角的增大,NMF映射函数下NRMS值逐渐优于GMF和VMF1下的NRMS值。处理数据量大的CORS站数据,GMF映射函数具有最佳的改正效果,对我国北斗导航定位系统应用映射函数具有参考价值。

| Abstract: | Different tropospheric mapping function influences the data solution of CORS station.To obtain the troposphere delay solution strategy in northeast region of China,the CORS data are used in the comparative analysis in this paper.The conclusion shows:with the satellite elevation cut-off angle increasing,NRMS of NMF gradually is higher than that of GMF and VMF1;while processing large amount of data CORS data,GMF mapping function will produce the best correction effect,which provides reference value for the application of the Beidou navigation and positioning system. |
