摘要
对于GPS网空间直角坐标系与原有城市控制网的高斯平面直角坐标系之间的转换,本文介绍了一种新的方法,即借助于一个区域性辅助椭球,由此得出的GPS测点的高斯平面直角坐标所依据的中央子午线位置和边长归算面均能与城市控制网原有基准一致。
In order to reduce the GPS baseline vector to the datum of the urban control network, this paper presents a new method, in which an auxiliary ellipsoid is introduced and applied by means of the initial value of terrestrial network.
