| 摘 要： | GPS测量的大地高精度达到了3×10-6～4×10-6,本文结合城镇控制测量对GPS高程拟合情况进行了分析。研究结果表明,通过施测少量均匀分布的GPS点的水准高程,采用BP神经网络方法拟合GPS点正常高可以部分替代水准高程或三角高程。

| Abstract: | The accuracy of geodetic height GPS measurement has reached 3×10-6~4×10-6.This paper analyses GPS elevation fitting in the light of town control surveying.Research shows that surveying height of a small amount of evenly distributed GPS points using BP neural network for GPS height fitting can replace part of leveling or trigonometric leveling. |
