摘要
本文提出了T2000电子经纬仪与PC-1500计算机联机系统（简称TPC系统）及工作原理。该系统能实现对大型设备精密校准测量的数据采集，传送、处理自动化。作者成功地把该系统用于抛物面天线的校准测量。文中详细说明了数据处理方法，分析了各项主要因素对天线校准测量的误差影响。结论指出：TPC系统能达到±0.6毫米的点位精度，不失为用于大型设备安装或精密校准测量的一种先进手段。

This paper introduces a system that two Wild T2000 electronic theodolites are lin ked with a PC-1500 pocket computer (TPC system) The system can-, be used in auto matically collectting, transmitting and processing the measurement data of large equip ment The author have successfully surveyed a large paraboloid antenna with the system The paper discnbes data deallmg method of calibration survey for the antenna by three dimension angly intersection, the formula of transforming the coordinates of point on the antenna's surface from the survey coordinate system to a standard coordinate system, and the formula of calculating normal correction The paper also analyses the effects of errors in the antenna measurements It is pointed out in the end of the paper that the TPC system can reach ?. 6mm mean position error It is a advanced system used to survey large paraboloid antenna
