摘要
GPS技术得到了广泛地应用,但是GPS测量的高程属于大地高,而我国采用的是正常高系统。因此通过数据拟合的算法得到GPS控制点的高程异常,然后将大地地高转换为正常高系统,才能在工程中使用。
It has long been confused since GPS has a wide application that normal height is used in our country but ellipsoidal height is obtained in GPS. Yet height anomaly of control points can be secured by data fitting. Then ellipsoidal height is converted to normal height. So it becomes available in projects
