Abstract:

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.
