| Abstract: | The annual period changes of zenith tropospheric delay for two years were calculated from the observations of 9 GPS continuously operating stations in Tianjin area as well as 4 IGS reference staions, and the time space correlations of zenith tropospheric delay at different locations were analyzed. The results show that the mean values of differences among stations are about ±4 mm , the standard errors are better than 1cm; the mean values of differences between the data of 2006 and 2007 are about 9mm , the standard errors are better than 4cm. |
