| 摘 要： | 近代平差的对象已从同类观测值扩展为同类不同精度或不同类多种观测量,且现在的测量手段早已不限于传统测量,这就不仅要研究不同类观测量参数估计的方法,而且还要研究如何准确地确定不同类观测量之间的权比,以提高平差结果的精度和可靠性。但由于粗差与随机模型误差的相互影响,使得平差结果的可靠性大大降低。将针对上述情况,提出含有粗差的Helmert方差分量估计方法,用于处理观测值含有粗差时的方差分量估计。

| Abstract: | In the Modern Geodesy,the object of Adjustment has enlarged from homogeneous observation to different accuracy or inhomogeneous observation,and now the surveying method has not limited to traditional measure.In order to improve the reliability of adjustment result,it is necessary not only to research the method of in homogeneous observation parameter estimation,but also to study how to exactly determine the power ratio of in homogeneous observation.But because of inter-influence of coarse error and stochastic model error,the reliability of adjustment result had been degraded greatly.In this paper,the method of Helmert Variance Component Estimation which including gross has been brought forward aiming at above-mentioned instance and dealing with variance estimation of observation including gross. |
