摘要
本文编写三维测量精度统计及单位权中误差计算程序,对BEPCII储存环2007年-2010年激光跟踪仪测量原始数据进行分析,计算相邻测站测量边角差。通过大量的实际测量数据分析,得到激光跟踪仪在环中实际的测角精度和测边精度,用以在测后平差中定权。
A program was written to analyze the precision of laser tracker in BEPCII storage ring, and calculate the mean square error of unit weight in the paper. The measuring data of laser tracker in BEPCII storage ring from 2007-2010 was analyzed, and the difference of distance and angle in adjacent measuring stations was calculated, including slantwise distance difference, horizontal dis- tance difference, horizontal angle difference and vertical angle difference. Finally, through the analysis on field measuring data, the ac- tual measuring angle precision and measuring edge precision were given to calculate the mean square error of unit weight in survey ad- justment.
