摘要
在高精度轨道安装与校准中经常会用到准直测量方法,准直测量中,视距和对中误差对精度影响较大。提出了一种全站仪任意设站的方法,能够有效缩短视距和避免对中误差,并对其精度进行了分析。结果表明,准直测量方法工作量小、精度高、操作简单,能够满足高精度大长轨道安装的精度要求,为同类工程提供了有益参考。
In the high-precision orbit installation and calibration,the aligment measurement method is often used. In the collimation measurement,the line of sight and the alignment error have a great influence on the accuracy. This paper proposes a method for arbitrarily setting up stations with total station,which can effectively shorten the line of sight and avoid the alignment error,and analyze its accuracy. The results show that the proposed collimation measurement method has small workload,high precision and simple operation,and can meet the precision requirements of high-precision long-long track installation,which provides a useful reference for similar projects.
