多期复测水准网的动态平差

On the Dynamic Adjustment of Levelling Networks for Repeated Observations in Different Epochs

  • 摘要: 本文在2、3的基础上,提出了两种多期复测水准网的动态平差方案:①、附有速率参数λ的线性运动模型下的动态平差;②、附有加速率参数γ的非线性运动模型下的动态平差。并简述了这两种平差方案的选择原则及其对平差结果带来的差异。最后论述了水准网动态平差的几个重要特性。

     

    Abstract: On the basis of2 and3,this paper put forward two dynamic adjustment schemes of repeated observations in different epochs:(1) a dynamic adjustment of linear kinematic model with a velocity parameter λ;(2) a dynamic adjustment of nonlinear kinematic model with an acceleration parameter γ.This paper deals with the principle for the choice between these two adjustment schemes and the difference of the results from these two kinds of adjustments.Finally,some important characteristics of a dynamic adjustment of levelling networks are presented.
