对高精度全站仪用于大中型天线安装测量进行了有益的尝试。坐标测量采用TDA5005全站仪配合测距反射片，导出了测距入射角计算公式，提出了一种反射片加常数测定方法。在数据处理方面，讨论了标志厚度对面型的影响。计算发现，对于圆抛物面天线而言，曲面自由拟合法与CAD面型拟合法是相当的。天线机械调整效果得到了电测结果的验证。

A TDA5005 total station with a large mount of reflector tapes was successful used in a large antenna's installation.The algorithm of distance incident angle was drawn.A new method for tape distance constant was developed.The offset correction for tape was also discussed.From this paper,it was found that the two methods,which were called surface free fitting and CAD surface fitting,were all the same for circular paraboloid.The effect of mechanical adjusting was proved by electronic testing.
