摘　　要：概述了NMF、VMF1、GMF 3种映射函数模型,借助IGS站和CORS站观测数据使用GAMIT软件分析了对流层映射函数对区域CORS网解算精度的影响,实验结果表明NMF、VMF1、GMF 3种映射函数模型对山东省CORS网解算精度结果相当,考虑到解算效率和映射函数模型的全球适用性,在山东地区推荐使用GMF映射函数模型。In this paper,we introduced three mapping function models of NMF,VMF1 and GMF.Then,based on the observation data of IGS and CORS stations,we used GAMIT software to analyze the influence of tropospheric mapping function on the accuracy of regional CORS network.The experimental results show that NMF,VMF1 and GMF 3 can improve the positioning accuracy of regional CORS network.Considering the efficiency and global superiority of the mapping function model,it is recommended to use the GMF mapping function model in Shandong Province.
