| Abstract: | In order to indicate actual displacement objectively and reasonably,a robust estimation with minimum first order norm of displacement component is offered to determine relative stability displacement,and it does not have to make any assumption for deformation of points,being different from ordinary quasi-stable adjustment.A new form of geodetic coordinates is adopted to express displacement for effectively judging relative stable points with horizontal and vertical orientation.Two stages of data from GPS deformation monitoring net in Shanghai area are calculated with this method to prove that this method is feasible and effective for strain analysis. |
