摘要
在分析 GPS测高理论的基础上 ,提出了用建立基础高程面和加入山区重力异常改正的方法 ,实现山地区域 GPS精确测高 ,并用实例进行了检核 ,达到了四等水准测高精度要求。该方法还可减少
On the bases of analyzing the theory of GPS height survey, the author put forward a method to survey height accurately with GPS in mountain area by setting up a basic height surface and adding a correction of abnormal gravitation in mountain area. A solid example demonstrated it , not only reached the fourth degree of accurate leveling height, but also decreased much work which needs in the normal way to connect surveying with leveling.
