摘　　要：空间飞行器在复杂多变、环境恶劣的太空环境中需要保持连续稳定地工作数年。为了适应复杂的太空环境,完成空间中的探测、定位、通信等任务,星载电子设备以片上系统(SOC)作为主控芯片通过软件版本切换、地面上注更新以及软件程序纠错等软件动态部署技术,实现系统的软件重构功能。该功能很好地解决了星上载荷工作参数动态更新的需求,以及不同的飞行任务或任务的不同阶段需要采用不同工作模式的问题,提升了系统灵活性及可靠性。Space vehicles need to maintain continuous and stable operation in the complex and changeable space environment years.In order to adapt to the complex space environment and complement exploration,positioning,communication and other tasks in space,spaceborne electricity uses System on Chip(SOC)as the main control chip to switch software version,update the ground injection and correct the software program error and other software dynamic deployment technology,to achieve the system software reconstruction function.This function can be a good solution on the satellite requirements of dynamic update of payload working parameters can solve the needs of different flight missions or different stages of missions.The system flexibility and reliability are improved by using different working modes.
