| 摘 要： | GPS测量已能够提供毫米级的平面坐标，但因似大地水准面与参考椭球面的差距，使得高精度的GPS大地高不能直接应用于生产实践。如何将GPS大地高转化咸水准高程，并使其保持一定的精度，一直是人们研究的热点。在介绍GPS高程拟合模型的基础上，通过实测数据验证了GPS高程拟合代替水准测量的可行性。

| Abstract: | Plane coordinates of millimeter level accuracy can be got by GPS survey, but precise GPS ellipsoidal height isn＇t applied in practice, because of the separation between quasi-geoid and reference ellipsoid. So it＇s always a hot topic how to transform GPS ellipsoidal height into level elevation and to keep certain accuracy. Based on the introduction of GPS elevation fitting model, the availability that leveling is replaced with GPS elevation fitting is verified using measured data. |
