In order to solve the shelter problem of GPS network and state control points conjunction, a method of constructing virtual vector was put forward in this thesis.

针对GPS控制网与国家控制点联测时遮挡严重的问题,提出了一种虚拟基线的方法,即通过常规方法测出GPS网中某点与国家控制点之间的基线构造元素,并利用WGS84地心坐标系与站心地平直角坐标系之间的转换模型计算出国家控制点的WGS84地心坐标,然后根据GPS商业处理软件的基线格式构造出GPS网中某点与国家控制点之间的虚拟基线,并入整个GPS控制网中进行平差解算。
