Abstract A new model for estimation of zenith tropospheric delays by regional CORS data without any meteorological data was presented，based on the investigation of the relationship between tropospheric delay and the elevation and longitude. Then the accuracies of new model are compared with the direct interpolation method and removerestore method by using the data from Guangxi CORS，respectively. Research results show a significant improvement for the calculated precision with the new model.
