浅析相对无偏估计在测量平差中的应用

Discussion on the application of relative unbiased estimation in measurement adjustment

通过分析测量平差实际问题,提出相对无偏估计,并利用实例验证,得到结论是测量平差是当观测量完全等价时,采用相对无偏估计更能正确得到其最或然似值。

By analyzing the practical issues concerning measurement adjustment,this paper brings up relative unbiased estimation and adapts case verifications,the result of which shows that when the measurements are equal to each other exactly,the best possible approximate value of the measurement adjustment can be obtained correctly by adapting of the relative unbiased estimation.
