摘要
论述了在隐蔽地区用两颗GPS卫星进行变形监测的原理。经模拟测试 ,验证了其原理是正确的。
This paper discusses the theory of deformation monitoring by two GPS satellites in the snug area.Through a simulation test the theory has been proved to be correct.Finally this paper also introduces observational program of deformation monitoring by two GPS satellites.
