Codesign mechanics / attitude control for a simplified AOCS preliminary synthesis

This paper aims to present the advantages of a multibody modeling approach, adapted to all kinds of satellites. This approach gives not only a linearized satellite model at a nominal parametric configuration but also a linearized parameterized model available on a parametric range. Resulting dynamic models are representative of the couplings between different axes and the impact of flexibility. The two contributions of the paper concern the ability of these dynamic models to simulation purposes and the parameterization of the overall satellite model in terms of the inclination of a flexible appendage, useful for a parametric sensitivity study
