摘　　要：介绍了NMF、VMF1、GMF 3种映射函数模型,借助CMONOC站和IGS站观测数据使用GAMIT/GLOBK软件分析了对流层映射函数对CMONOC网解算精度的影响,实验结果表明在进行CMONOC网解算时,NMF、VMF1、GMF 3种映射函数模型解算精度结果相当,考虑到映射函数模型的全球适用性,推荐使用GMF映射函数模型。In this paper,we introduced NMF,VMF1 and GMF in detail at first.Based on the observation data of CMONOC and IGS stations,we used GAMIT/GLOBK software to analyze the influence of tropospheric mapping function on the calculation accuracy of CMONOC network.The experimental results show that the accuracy of NMF,VMF1 and GMF mapping function models are similar.Considering the global applicability of the mapping function model,GMF mapping function model is recommended.
