摘　　要：全国三级GPS大地控制网是基础测绘长期的建设项目,充分利用各类工程建设的高等级GPS控制点,不仅可以提高三级GPS大地控制网布设精度,而且还可以加快三级GPS网的建设。提出了基于高等级GPS控制点的三级网计算方法,并针对某区域进行了试验分析。The third-order GPS geodetic network is a long-term construction project of national basic surveying. Making full use of advanced GPS reference points of all kind of project can not only improve the accuracy but also accelerate the construction of the third-order GPS geodetic network. The calculating method based on advanced GPS reference points for the third-order GPS geodetic network is introduced and the data of an area is used as an example.
