In this paper, we study on-orbit identification algorithm for Multi-Input Multi-Output Large Space Structure(LSS) system which has four RCSs and six atitude angles and rates measurement outputs. In the proposed method, the state-space model is firstly realized by singular value docomposion of Hankel matrices, then, by iterative least square curve fitting process, the modal shape is realized using time response signals. Its ability is confirmed through a numerical study.
