A GNC Double Super-Real-time Hybrid Simulation System Applied To Long Period Guidance Task

A GNC mathematical simulation system with double super real-time hybrid simulation capability is proposed to meet the rapid and reliable simulation test, when the system applied to the long time consuming GNC autonomous navigation and guidance task. The system can use with two kinds of super real-time simulation capabilities, named "super real-time of running acceleration" and "super real-time of state jump". Super real-time of running acceleration can realize the closed-loop super real-time simulation of GNC system in the whole process of task "control action" with high simulation accuracy, but the simulation super real-time acceleration ratio is relatively not high. State jump super real-time is recursive oriented to super real-time rapid state in the task "no control" free operation stage. For the long-period guidance mission, it greatly improves the simulation acceleration ratio with the way of ignoring the task "irrelevant" process. These two super real time technologies can be used in coordination and mixed simulation, which can combine the advantages of both, to perfectly meet two demands of the simulation authenticity and rapidness of GNC long period guidance mission.
