Initial design of FAST engineering surveying control network1

摘要

The high precision surveying control network provides the positional and orientation datum for the construction and measure-control system of the Five- hundred-meter Aperture radio Sphere Telescope(FAST), which is deployed at the typical Karst depression. The design of the control network is in accordance with the 1:1000 topographic maps. The issues about the control station site selection ,distribution and construction are analyzed and discussed, and the initial results are provided in this paper.
