Abstract Mapping function is one of the most important parts in troposphere delay correction. Selecting a highprecision mapping function has great significance for data processing. Some mapping functions of highprecision troposphere delay correction models are listed,analyzed by use of the GPS observation network data composed by SCIGN, PBO and IGS partial stations and compared with each other from the viewpoint of input values with GAMIT software. The results indicate that the accuracies of Niell and GMF models are perfect, and GMF model is fitter to be used in Asian areas.
