摘要:
在利用GPS建立公路勘测首级控制网时,控制网本身特性决定了异步环边长较为悬殊,若按常规方法将所有合格的基线一同进行平差则存在明显的不合理性.本文从工程应用的实际出发,提出了一种行之有效的优化处理方法.此法的实质就是在内业平差处理时将形成异步环的较长边仅用于基线成果的检核,不纳入网平差计算的范畴,在不损失观测值精度的前提下能以较大幅度提高整个GPS网的点位精度.工程实践表明,此法具有较好的工程实用价值.
Abstract:
In establishing GPS framework of highway survey, the long-edges of asynchronism loop are widely different by itself feature. It is obviously unreasonable if all qualified baselines are adjusted in light of routine method. In this paper, an effectiveness optimization treatment method is put forward. The essence of the method is that the rather longer edges of asynchronism loop are only used in checking baseline observation results and not used in adjustment treatment.Not reducing the measurement precision, the method can raise the point precision of GPS framework. Engineering practice indicated that the method is of some practical engineering value.
