线路测量中GPS高程拟合的应用研究

The applied research of GPS high-rise fitting in route survey

介绍了GPS高程拟合原理,运用平面拟合和多项式函数拟合两种GPS高程拟合方法,对不同地形和长度的两个测区进行了处理,并比较了两种方法的优缺点,提出了选取GPS水准联测点时的注意事项。

With an introduction on the principle of GPS high-rise fitting, applying two GPS high-rise fitting methods of plane fitting and polynomial functions fitting, it processes two surveying areas with different terrain and different length, compares the advantage and disadvantage of two methods, and then proposes precautions in choosing GPS leveling joint method.
