摘要
针对导线测量中棱镜常数设置错误的情况,分析了导线验算无法检核棱镜常数使用错误的原因,研究了棱镜常数使用错误对平差结果的影响,提出了导线测量中棱镜常数使用是否正确的检测方法,通过使用该方法可以避免距离测量的粗差,从而保证导线测量的精度。
This paper analyzed the reason that the using fault of prism constant could not be detected during traverse checking calculation, according to the incorrect setting of the prism constant in traverse surveys, then studied the influence Of prism constant on traverse adjustment ,put forward the checking method of the prism constant setting. The method could avoid the error of prism constant using and ensure the precision of traverse survey.
