| Abstract: | Tropospheric delay density is resolved with the ground??based GPS monitoring network data in USA solved by the GAMIT/GLOBK software based on tropospheric slant path total delay virtualized by back??projection method. Tropospheric delay 3D feature is analyzed by the method of tomography.The result shows that zenith total delay solved by two methods is small, the maximum error is less than 5 mm, and the mean square is 4.1 mm. |
