Abstract:

Trimble Total Control software has the ability to set the parameters calculated from the international WGS-84 coordinate system to a local coordinate system which uses these parameters to make the transfer coordinates to a local coordinate system was chosen. The article compared the results with data processing software Trimble Total Control in the case of use and do not use the parameters to transfer the coordinates from the international WGS-84 coordinate system to the national VN-2000 coordinate system GPS network on the Geodesy practice area in Lang Son
