Abstract In order to further improve the accuracy of regional tropospheric delay model without meteorological parameters, a new model is proposed and taking the GPS data of Hong Kong CORS as an example. The modeling process has two main steps, the first is to analyze the periodical characters of wet and dry components tropospheric delay and the factors which affect the wet and dry components respectively, the second is to model based on the correlation between tropospheric delay and spacetime. The test result shows that the new model is more precise than the UNB3.
