摘要
本文简要介绍了GPS高程拟合的理论方法及数学模型，结合小测区GPS像控点测量的作业实践，对GPS高程拟合方案进行比较和分析，得出了起算点的空间分布、起算点的数量和拟合方法对高程拟合精度的影响，提出了解决此类地区像片控制测量GPS高程拟合的解决方案。
The theory of GPS height fitting is introduced briefly as well as the corresponding mathematical model in this paper. Combined with surveying practice of GPS control points in small survey area, some GPS height fitting schemes are compared and analyzed, and the influences of the spatial distribution, the amount of control points, and fitting methods on height fitting precision are concluded. At last, a solution to GPS height fitting in these regions is put forward.
