光学经纬仪一测回水平方向标准偏差测量不确定度评定

Evaluation of Uncertainty of Measurement for One Measuring-Process Standard Deviation in Back Horizontal Direction of Optical Theodolites

分析了检定光学经纬仪“一测回水平方向标准偏差”的误差来源 ,并确定了它的合成标准不确定度和扩展不确定度。

In this paper, the error source of one measuring process standard deviation in horizontal direction of optical theodolites is analyzed. The combined standard uncertainty and expanded uncertainty of this standard are evaluated.
