摘　　要：在较大区域(近万平方公里)建立高等级的GPS控制网不是一项普遍的工作,特别是网的设计、起算点选取、新点位布设、施测、基线解算、独立基线选取、GPS网平差和精度评价等。成功的经验对以后的工作具有借鉴和指导意义。It was not the common work to establish the high grade GPS control network in a relatively large area（ nearly ten thousand square kilometers）,particularly to the design of the network,selection of the starting point,setting of the new points,surveying,base line processing,selection of the independent base line,GPS network adjustment and the precision evaluation and so on. The successful experience had the implications and the guidance for the work in the future.
