| 摘 要： | CPS测量的高程系统是GPS大地高系统,它以参考椭球面为基准面,而我国采用的高程系统是正常高系统,是以似大地水准面为基准面.二者不是处处平行,所以需要将GPS大地高转换为正常高,求出已知点的高程异常,从而拟合出未知点的高程异常,本文主要阐述了多项式高程拟合模型中的二次多项式拟合和三次多项式拟合.通过对这两种常用的多项式... |

| Abstract: | The GPS survey forming a Elevation System is the GPS Geodetic Height system which takes reference ellipsoid as the datum plane;and the elevation system of China is the normal height system which takes the quasigeoid as the datum plane.The two are not always parallel,so it needs to transform Geodetic Height to normal height system,that is calculating the height anomaly.This paper focused on two and three polynomial fitting in polynomial fitting methods.By analysising these two common polynomial fitting model... |
