CONCEPTUAL RESEARCH ON OPTIMIZATION OF SYSTEM PARAMETER OF OPTIC REMOTE SENSING SATELLITE

Combined with the traditional satellite design and modern optimization method, a flowchart of satellite system optimization design is presented. First, mission objectives and mission requirements are decided. Then, the optimal selection of satellite system scheme is processed with the method of fuzzy multiobjective optimal selection. Finally, the design variables, constraint conditions and objective functions of satellite system parameter design optimization are determined and the optimization models of cost, performance, ratio of cost to performance, reliability and multiobjective are built. Furthermore, the results of four single objective optimizations and their multiobjective optimizations are compared.
