GPS网的建立必须经过图上设计和实地实施两个过程。GPS控制网的建立必须充分考虑控制点的点位、起算点的选择、连接方式、重复基线的选择和地面观测量的选择等各种因素。文章提出了基于AutoCAD2000的GPS网模拟设计新方法,讨论了AutoCAD电子地图上GPS网的表示方法,并利用Visual Basic 6.0语言编程,提取出GPS网信息,以控制点文件和基线向量文件保存。 The establishment of GPS network must go through the process of designing the map and implementing it in the field. The establishment of GPS control network must take full account of the control point of the point, starting point selection, connection, repeat the baseline selection and selection of ground observation and other factors. This paper presents a new method of GPS network simulation design based on AutoCAD2000, discusses the representation of GPS network on AutoCAD electronic map, and uses Visual Basic 6.0 language programming to extract the GPS network information to control the point file and the baseline vector file preservation.
