摘　　要：随着CORS的应用普及,利用CORS基准站为起算数据能够快速布设控制网,但是由于CORS基准站为CGCS2000坐标框架,因此,只能获得控制点的大地高。本文结合实例对GPS拟合高程、水准、大地水准面几种获得高程的方式进行对比分析,给出能有效解决高程问题的方案,具有重要的现实意义。With the popularity of CORS,using the CORS base station for initial data to rapid deployment of controlnetwork,but due to the CGCS2000coordinate frame of CORS base station,therefore,can only get the control pointsof the earth high.This paper analyzed on GPS Fitting elevation,leveling,the geoid obtained several methods comparatively and gave a good solution to the problem of the elevation scheme,which has extensive practical significance.
