摘要
地面导线测量中,通常使用GPS静态测量的方法获得未知点坐标,因此一般不存在支导线测量;但井下测量时无法进行GPS定位,常常面临支导线测量的情况。为解决这一问题,本文提出了几种支导线测量方法与相应的精度保障措施,分析了改进后的支导线测角精度。结果表明,加测陀螺坚强边可以极大地提高支导线测角精度,相关方法可以为支导线测量工程提供参考。
In the ground traverse survey,the method of GPS static survey is usually used to obtain the coordinates of unknown points,so there is generally no branch traverse survey;however,GPS positioning cannot be carried out in the underground survey,so branch traverse survey is often faced with.In order to solve this problem,this paper puts forward several survey methods and corresponding accuracy guarantee measures,and analyzes the improved angle measurement accuracy of branch traverse.The results show that the angle measurement accuracy of the branch traverse can be greatly improved by adding the strong edge of the gyro,and the relevant methods can provide reference for the branch traverse measurement engineering.
