摘　　要：提出利用激光跟踪仪建立精密三维控制网的具体方案,并对测量数据进行了相邻站拟合、边角重复测量统计等预处理。结果表明,相邻站数据拟合点位偏差在0.2 mm之内,距离重复测量精度为0.04 mm,水平角重复测量精度为2.48″,垂直角重复测量精度为3.92″。采用两种数据处理方法分别进行平面和高程平差,平面绝对点位精度0.08 mm,相对点位精度0.02 mm,高程点位精度0.06 mm,满足粒子加速器精密安装的要求。This paper presented a specific plan for the establishment of precise 3 D control network using laser tracker, and preprocessed the data by fitting between contiguous two stations and statistics of repeated measurement of sides and angles. The results indicate that the fitting offset between contiguous two stations are within 0.2 mm, the repeated accuracy of distance, horizontal and vertical angle respectively are 0.04 mm, 2.48 seconds and 3.92 seconds. This paper used two data processing methods to do plane and elevation adjustment respectively. The absolute positional accuracy, relative positional accuracy in plane and accuracy of elevation are 0.08 mm, 0.02 mm and 0.06 mm respectively, attaining the goal of installation of particle linac.
