| Abstract: | In this paper, the six degrees-of-freedom simulation mathematical model of the GNC system is built at first. And then it has also done some researches and discussions, such as how to eliminate the interconnection influence among the different control channels and among the motion equations, how to analyze the Influence of navigational errors on the impact point precision, how to investigate the influence of six degrees-of-freedom trajectory computation on the steering and guidance laws. Finally this paper has analyzed how to put together all subsystems of GNC of the reentry vehicle to implement six degrees-of-freedom mathematical simulation, and discussed some problems which could be solved by the integrative mathematical simulation. |
