摘要: 对流层映射函数是卫星高度角及其他一些因素的函数,它的好坏直接影响对流层延迟改正的效果。本文介绍了NMF、VMF1及GMF 3种模型,采用2016年陆态网及周边IGS站数据,通过GAMIT软件计算对比分析了3种映射函数对陆态网解算精度的影响。结果表明,在进行陆态网解算时,3种映射函数模型精度差别不大,截止高度角为10°时精度最佳。

关键词: 对流层, 映射函数, 陆态网, 截止高度角

Abstract: The tropospheric mapping function is a function in regard to the height angle and other factors, which has a direct influence on the tropospheric delay correction. This paper introduced NMF,VMF1 and GMF models,used GAMIT/GLOBK calculate the data of CMONOC and some IGS stations around China,compared and analyzed from the aspect of the effects of three kinds of mapping function to the accuracy of CMONOC solution.The results show that the accuracy of the three mapping function models is not very different, and the accuracy is the best when the height angle is 10 degrees.

Key words: tropospheric, mapping function, CMONOC, cut-off height angle
