Research on spacecraft design for ORS based on the systems theory

The unpredictability and uncertainty of Operationally Responsive Space (ORS) missions have brought new challenges to traditional spacecraft design methods, in which the satellite and the launch vehicle are designed independently. In this article, a novel integrated design method for ORS spacecraft design has been proposed by analyzing the characteristics of the ORS missions according to the system theory. Firstly, the feasibility of the integrated design method is analyzed. Then, qualitative analyses of integrated design method for the subsystems of the traditional satellite and the launch vehicle are carried out. Finally, the advantages of the integrated design method are demonstrated through quantitative research, especially for the uncertain space missions. Simulation results show that the integrated design method is an effective technology to realize unpredictable ORS missions.
