The characteristic of this approach is the iterative weighted similarity transformation in which the displacement vector d is transformed into a datum determined by points with a smaller coordinate difference between two epochs. The article first gives a theoretical background of the approach, and then the approach is applied to the case of simulated measurements in two epochs. The calculated results of the deformation analysis approach with the robust methods in the present case do not differ significantly from the results obtained by conventional deformation analysis approaches.
