摘要
本文讨论了在解析法求测距仪加常数时,通过将观测值分组,用方差分量估计原理来拟合测距仪精度评定公式α+bppm的方法。结合实测数据,还介绍了观测值的粗差检测等问题。
To determine the accuracy formula a+bppm of EDM, the variance component estimation can be applied by dividing all the observations into some groups while calculating the additive constant 'c' using analytical method. A case example is given and the problem of gross-error detection in observations also disscussed in this paper.
