摘　　要：CORS的各基站通过长时间连续不断的观测能获得高精度的大地高和高程异常,基于CORS的GPS工程控制网各点也能获得高精度的高程异常,从而获得高精度的正常高。本文对这一方法实现的可能性进行了分析,并在实践中进行了检验。By long-time continuous observation,we can obtain high-precision geodetic height and height anomaly.At the same time,each control point of GPS engineering control network based on CORS obtains high-precision height anomaly,accordingly the high-precision normal height is obtained.The possibility of realizing this method has been analyzed in this article,and also tested in practice.
