常规的粗差探测方法 ,不仅对粗差的定位效果不理想 ,而且对粗差大小的确定更显得无能为力。本文应用抗差估计理论 ,对一模拟水准网进行了粗差探测 ,结果表明 ,抗差估计不仅能准确地对粗差进行定位 ,而且也定量地反映了粗差的大小 ,并且实现了粗差探测和平差计算同步完成的目标。 Conventional gross error detection method, not only for poor positioning effect is not ideal, but also to determine the size of gross errors even more powerless. In this paper, the theory of anti-error is used to detect the gross error of a simulated leveling network. The results show that the anti-error estimation not only can accurately locate the gross error, but also quantitatively reflects the gross error, and realizes the gross error Detection and balance calculation to achieve the goal of synchronization.
