摘　　要：从GPS高程测量应用问题入手,简述了GPS高程拟合的原理,介绍了曲面拟合法、最小二乘配置拟合法和基于kriging统计的移动曲面法3种高程拟合方法,并通过某地区GPS/水准点数据进行了实验比较,得出了一些有益的经验结论。In order to solve the GPS elevation surveying problems in the project,the principle of GPS elevation fitting was discussed in this paper.Three GPS elevation fitting method:the surface fitting,the least squares collocation fitting,mobile surface fitting based on statistics of kriging was introduced,and compared by the GPS leveling experiment in certain area,several benefit conclusion were derived.
