摘　　要：空间站在轨组装和长期运营阶段涉及到多飞行器独立飞行、飞行器间交会对接、多飞行器组合体融合控制、多飞行器分离过程控制和飞行器返回再入等复杂飞行任务,完整、真实的飞行模拟是必需且至关重要的.基于时间同步、实时数据交换的分布式一体化仿真架构,设计了一种多飞行器协同的通用半物理制导、导航与控制(guidance,navigation and control,GNC)系统飞行模拟平台,可很好地满足复杂系统的飞行模拟需要.平台由若干灵活、可扩展的通用模拟器构成,单个模拟器通过配置可以实现任一飞行器的功能,能够独立对指定飞行器的全任务过程进行仿真.平台通过靶场仪器组B时间码(inter-range instramentation group-B,IRIG-B)信号进行时间同步,利用1553B总线完成动力学仿真数据实时交换,并在多模拟器之间通过协调机制实现热并网后进行协同仿真.该模拟平台成功应用于空间站飞行控制演练.A method for designing simulation platform of the spacecraft Guidance Navigation&Control(GNC)sys-tem is proposed.During the in-space assembly and long term operation of the Chinese Space Station,complex flight missions are involved,including multi-spacecraft individual on-orbit flight,space rendezvous and docking,multi-spacecraft combination fusion control,separation process control and spacecraft re-entry.The integrate and realistic flight simulation is necessary and vital.Based on time synchronization,real-time data exchange,distributed and in-tegrated simulation architecture,a universal multi-spacecraft collaborative Hardware-in-the-Loop(HIL)simulation platform of GNC system is proposed,on which integrate flight simulation with high fidelity is possible to be a-chieved.The platform consists of several universal simulators,which are highly flexible and expandable,and each can be configured as any specific spacecraft and perform the spacecraft’s whole mission process flight simulation in-dependently.The platform synchronizes time via IRIG-B code and exchanges dynamics data on 1553B bus in real-time,and multi-spacecraft co-simulation can be implemented after coordination accomplished among simulators.This simulation platform has been successfully applied in a spacecraft flight control drilling program.
