This paper proposes a method for identifying the modal parameter and estimating attitude and deformation of the large flexible structure such as the International Space Station by kinematic GPS. Eigensystem Realization Algorithm method is used for the modal parameter identification, and for attitude and deformation estimation, the Kalman filter is adopted based on its identified system dynamics. The proposed method was evaluated through the computer simulations and the ground-based experiments, and the results confirmed its feasibility.
