Abstract：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.
