| Abstract: | This paper proposes a method and flow for data processing and stability analysis of deformation monitoring network based on the rank defect free network adjustment.The strategy can resolve the confirmation of robust iterative weights during several periods of observation.Then,analyzes the point’s stability of the network by the method of mean gap,which is proved practically and can reflect stability of deformation monitoring network correctly through the computational example. |
