Abstract:Aiming at the development problems in the spacecraft control system software, including complex management, disordered development process and low-level of collaboration, a collaboration evolution method of the spacecraft control system software was proposed. Firstly, the activities and strategy of the software evolution process is defined and analyzed. After that, the strategy rules to direct the process of the spacecraft control system software evolution was established. Based on this method, the process of the software evolution could be constrained effectively, and the related participants could be coordinated as well. The development quality and efficiency of the spacecraft control system software would be increased significantly.
