GPS高程拟合的初步研究

Primarily Study on the GPS Height Fitting

全球定位系统(GPS)自从问世以来,已经在导航定位、授时、测速等方面发挥了巨大的作用,本次通过对GPS控制网中拟合高程的试验,对GPS高程拟合的应用和精度做了初步研究。

With the coming forth of Global Position System （ GPS）, GPS has been applied in navigation locating, time transfer, and testing speed, and other aspects, and performed important functions. This paper primarily studied the application and accuracy of GPS height fitting through the height fitting experiment of GPS control network.
