| Abstract: | Combinging with the establishment of the GPS test net of Shanghai with three dimensional deformation monitoing, this paper discusses some problems about establishing high precision GPS net. The result shows that if forced centering and orientation of receiver's antenna are adopted and the obseruation time is more than three hours, the observed GPS baseline less than 4km . can reach millimeter prerision. |
