| 摘 要： | 在参数和起算数据的先验统计性质已知时，提出了基于滤波的顾及起算数据误差的赫尔默特估计法。这种方法估计出了相对于起算数据基准的精度，既充分考虑了起算数据的影响又没有增加计算量，并且将平差计算与随机模型的赫尔估计同时进行，使数据处理过程更加完善。

| Abstract: | This paper brings forward Helmert estimating based on filtering considering error of original data, when knowing the statistical apriority of parameter and original data. The precision of this method is relative to the norm of original data. This method considers the effect of original data and the amount of count is not added. At the same time, estimating and Helmert estimating are carried through, that makes the disposal of data more perfect. |
