In order to apply intelligent technology to enhance the intelligent capability of spacecrafts, the intelligent level from deployment viewpoint was given. The start point of qualitative levels is automatic, autonomous and autonomic. It includes such capabilities as execution, self-learning, system self-management, mission self-management, thinking and planning from the bottom up. The behavior degrees are bottom-reactive, middle-program and high-thinking. According to the above capability levels, a 5-stage model and an intelligent architecture named “people shape architecture” were proposed. A human-body shape architecture was formulated with two supporting technologies (plug and play, autonomic control) to construct intelligent body on higher level. In this model, based on spacecraft onboard interface services and ESA packet utilization standard services, management information base and electronic data sheet were used for dataoriented design. Corresponding to the intelligent level, appropriate supporting capability of ground system was discussed. People shape architecture has some features including layering, modeling, unification for constructing of intelligent bottom-up architecture, and is open to use intelligent technology in higher layers.
