飞行控制模拟器,简称飞控模拟器,是飞控中心用来验证飞行程序和地面测控方案,训练操作人员的模拟仿真系统,为系统演练构造一个尽量逼真的任务环境.介绍了嫦娥一号飞控模拟器的功能、结构和使用模式.提出了带轨道根数跳时的新方法,使模拟器具备加速跳时至任意轨道段的能力,提高了任务演练的灵活性.建立了高精度轨道动力学模型,并首次在模拟器中直接嵌入了部分星载软件,大大提高了模拟器的保真度.同时专门设计了图形化的集中监控软件,方便了用户的操作和管理.该模拟器在嫦娥一号卫星任务准备中得到了充分的应用,为嫦娥一号卫星任务的圆满完成奠定了坚实的基础.根据该模拟器的开发经验,对未来模拟器的研制提出了几点建议.
Flight control simulator, referred to as flight control simulator, is a flight control center used to verify the flight program and ground measurement and control programs to train the operator’s simulation system for the system exercise to create a realistic environment as realistic as possible. Controlling the function, structure and mode of the simulator, a new method to track the number of track jumps is proposed, which makes the simulator have the ability of accelerating the jump to any track segment and improves the flexibility of task rehearsal.High precision orbit Dynamic model, and for the first time in the simulator directly embedded part of the onboard software, greatly improving the fidelity of the simulator.At the same time designed a graphical centralized monitoring software to facilitate the user’s operation and management.The simulator Which has laid a solid foundation for the successful completion of the Chang’e-1 satellite mission.According to the experience of the simulator development, some suggestions are put forward for the future simulator development.
