摘　　要：设计了硬X射线调制望远镜(HXMT)卫星数字伴飞系统,具有与在轨卫星相同的运行策略和控制模型。卫星发射后,通过配置参数使地面虚拟空间中的数字孪生体卫星与现实空间中的实体卫星状态一致,可"镜像"卫星在轨状态。结合数字模型状态量丰富、可加速运行、可反复运行的特点,在数字孪生体上开展卫星状态判读、卫星控制参数优化、卫星任务方案迭代仿真,得到上注至实体卫星的飞控数据,完成了卫星的任务规划和性能改善。The HXMT(hard X-ray modulation telescope)satellite’s digital twin companion sate-llite system is designed.The system has the same operation strategy and control algorithm as HXMT satellite on orbit.After launch,the system could simulate the actual state of HXMT sa-tellite on orbit by configuring parameters and status.With the digital twin,it is easy to simulate,optimize,and estimate.By simulation and optimization on digital twin,ground flight controllers could complete the mission planning and performance improvement.
