经纬仪检定装置测量不确定度分析

ANALYSIS OF THE UNCERTAINTY IN THE MEASUREMENT OF THEODOLITE VERIFICATION DEVICE

重点介绍目前国内应用较多由地震研究所生产的 JSJ- ZB垂直角目标系统与多齿台组合 ,按计量要求对该装置误差来源、标准不确定度及扩展不确定度进行了较详细的分析和计算 ,经分析和实践证明该套装置可满足目前国内外各等级经纬仪室内检定要求 。

This paper introduces in detail the testing instrument which is composed of JSJ 2B vertical angled object system and gear divided table, and analyses and calculates the error source, standard uncertainty and extended uncertainty of the instrument according the measurement requirement. It is tested that this sort of instrument can satisfy the indoor testing requirement of the presont all kinds of classes theodolites at home or abroad, after the analysis and the experiments. Thispaper can be consulted by the new standard built units and related technologists.
