摘要
首先建立了飞行器再入时制导、导航和姿控GNC系统一体化的六自由度数学仿真模型。然后对如何消除控制系统和运动方程的交连影响和导航误差给落点精度带来的影响进行了分析和讨论，同时还研究了六自由反弹道计算对导引和制导规律的影响。最后对飞行器再入时如何将制导、导航和姿控系统组合在一起进行六自由度数学仿真进行了分析和研究，并讨论了一体化数学仿真可解决的一些问题。
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.
