摘要
为了验证星载计算机的软/硬件性能,建立了以两个星载计算机为核心的卫星编队仿真验证系统。介绍了该系统的软、硬件构成,重点解决了动力学仿真机与星载计算机CAN总线双向数据传输、动力学仿真机以及星载计算机的进程同步、星载计算机的无线通信以及实时驱动STK场景动画显示等问题。在成功实现系统的基础上,进行了双星编队自主维持控制仿真。仿真结果校验了系统设计的合理性以及软硬件接口的正确性。
To verify the software and hardware performance of the on-board computer, a demonstration simulation system for formation flying satellites was established based on two on-board computers. The software and hardware architecture of the simulation system were introduced, and the key problems of the data communication between the dynamic simulation computers and the on-board computers via CAN bus, the synchronization of the dynamic simulation computers and the on-board computers, the wireless communication of the on-board computers, and the real-time visualization animation by driving STK were solved. Based on the developed processor-in-the-loop simulation system, the autonomous formation keeping control for dual satellites was performed. The simulation results demonstrate the validity of the simulation system and the correctness of the software and hardware interfaces.
