Satellite layout optimization design problems with complicated performance constraints are studied in this paper. In addition to the traditional geometric constraint, system centroid constraint, inertia angles constraint and dynamics performance, more complex design factors based on practical engineering requirements are considered, including thermal performance, CMA (compatibility, maintainability and accessibility) constraint and the special rules of the placement of special components. An enhanced interference algorithm based on finite-circle method (FCM) is proposed to handle CMA constraint, which can effectively control the distance between any two components. Moreover, to provide system engineers with the information of design space about dynamics and thermal performance, the accelerated particle swarm optimization (APSO) is proposed to optimize the constructed layout model globally. Finally, the feasibility and effectiveness of the proposed methodology are validated by a numerical test and an engineering example.
