		<abstract>Nowadays, satellites with rigid and flexible components are increasingly being extended to advanced applications, where solar panels, communication antennas, telescopic structures and robotics arms must achieve better pointing accuracy requirements. On the other hand, the guaranty of the controller performance depends not only on its good design but also on the knowledge of all states to be fed-back in order to improve the overall control system efficiency. As a result, control system design methods that include parameters identification and/or states estimation need more investigation to know their capability and limitations. In this paper, a Kalman filter methodology is used to recover the unmeasured states (elastic displacement and its rates) considering that only the states associated with rigid motion are measured (angle and angular velocity). In order to investigate the robustness of the filter, the Kalman filter methology is tested with a satellite model compose of one, two and three flexible modes. One observes that the fidelity of the estimation process increase with the inclusion of more modes in the satellite model, which in turn not affect the performance of the Kalman filter procedure.</abstract>
