摘　　要：探讨了GPS高程拟合的原理及精度评定,并结合淮南某矿区GPS平面控制网及三等水准网计算结果,采用GPS水准方法拟合出高程,将其与水准高程进行对比,对GPS高程测量的应用进行了探讨,提出了一些结论和建议,对研究GPS水准测量具有重要的意义。The principles of GPS height drafting and precision calcultion are probed into, and combined with GPS plane control net of somewhat mining area of Huainan, and the calculation result of third level net draws up height by GPS level method, contrasts them with level height in order to inquire into the application of GPS height measure, provides some solusion and suggestion, which has a great significence for reasearching on GPS level measurement.

关 键 词：GPS水准 高程拟合 高程异常 正常高
