The invention provides a lightweight spacecraft minimum safety system and an implementation method, aiming at reliable operation of a spacecraft in orbit, through configuration optimization of the minimum safety system, orderly power-up, cold and hot start and control time sequence configuration design are carried out on each component unit, and the reliability of the spacecraft is improved. The system configuration and construction method suitable for reliable operation of the lightweight spacecraft is provided, safe starting control logic and safe mode switching control logic of the spacecraft are achieved, communication of spaceflight energy flow, control flow and information flow can be ensured, the spacecraft operates orderly based on a minimum safety system, and the reliability of the spacecraft is improved. And effective support is provided for autonomous, safe and stable operation of spacecraft faults and ground emergency rescue. Through the configuration and construction method for the minimum safety system of the lightweight spacecraft, the reliability and safety of on-orbit autonomous execution of the lightweight spacecraft can be improved, and the influence of on-orbit faults on the safety of the spacecraft is reduced.
