摘要
介绍了水库大坝变形测量的精度要求,应用静态GPS接收机测量水库大坝变形监测基站网,对其精度与误差进行分析,并提出实现毫米级或亚毫米级GPS监测网的措施。
This paper briefly discussed the required accuracy about reservoir dam deformation surveying, and the analysed precision and error of the reservoir dam deformation measurent of the base station network by static GPS receiver. Finally put forward some measures for achieving minimeter level accuracy monitor network.
