In this paper, achieving of Stereo-Imaging scenario by a remote sensing satellite will be presented. Then a suitable attitude control system will be designed using 4 reaction wheels with pyramidal structure to fulfill large angle maneuvers of stereo-imaging scenario. The proposed attitude control system provide the satellite with the capability of nadir pointing and large angle maneuvers to take different images of a predefined zone from different point of view. In order to verify the performance of the designed attitude control system, a low-cost real time hardware in the loop test bed will be constructed. The constructed test bed is capable of assessing attitude control algorithms in a real time conditions. In the proposed test bed, accurate and real time modeling of satellite dynamics, space conditions, reaction wheels and gyroscopes will be done by the Simulator computer. Finally, performance of the designed attitude controller to achieve stereo-imaging scenario is investigated by implementing the algorithm in the hardware in the loop test bed in a real time condition.
