摘　　要：利用GAMIT软件估算香港连续参考站一年的对流层天顶延迟,建立了符合香港地区的以气象要素为参数的对流层改正湿延迟模型,且嵌入TRACK模块。经检验,TRACK模块中采用新模型比传统的Saastamoinen模型对提高GPS测量精度的贡献更为显著。The tropospheric zenith delay was analyzed through the one year of Hong Kong CORS system using GAMIT software, and a tropospheric zenith wet delay correction model was constructed according to the Hong Kong weather elements for the parameters, then we embedded it to the TRACK module. The result showed that the TRACK module improved the accuracy of GPS measurements by using the new model when comparing to the traditional Saastamoinen model.
