GPS survey has substituted for the initial routine geodetic survey and the engineering survey gradually because of its specialty,such as all-weather,high accuracy,,automation,high benefit and so on.Taking the primary control network of a university new campus as an example,the paper used three programs to adjust the control network with the support of the Pinnacle software,and then obtained the coordinates of each measured site.Research and analysis results show that the campaign mode adjustment program,which calculates all the independent baseline solution at one time,receives the highest accuracy.As a result,the final results of that mode can be applied to the subsequent planning and construction of the case study of the university new campus.
