Status flow of human spaceflight mission and implementations in flight control strategy

A flight control strategy is a procedure which is confirmed before mission and executed during mission. It imports mission status and produces commands by calculation. In this paper, started from basic principle, status transition of complex human spaceflight mission is defined as status flow. Thereafter, the thought of strategy making based on status flow is proposed. The status flow and strategy architecture is defined strictly so that it can be used for defining complex flight control strategies and improve reliability of the overall mission together with the inherent spacecraft system fulfilling the needs of complex human spaceflight missions in the future.
