摘　　要：针对小型化航天飞行器对综合控制系统的需求,结合目前国内外先进飞行器综合航电应用的经验,设计了一种以VITA74总线为基本架构的综合控制系统,使其在性能、功耗、体积等方面产生了大幅提升;利用SiP芯片内部的双核SoC芯片来运行主控程序及导航控制算法等功能,通过芯片集成的接口资源和可编程逻辑资源实现丰富的外围接口;给出了综合控制系统的硬件系统设计、软件系统设计及结构设计方案,并详细介绍了各个功能模块的设计思想;通过相应的性能测试试验,表明该系统工作正常,各项性能指标满足任务需求,可用于未来航天飞行器的使用。For miniaturized spacecraft’s demand of the integrated control system, combining the advanced aircraft integrated avionics application experience, a VITA74 bus based architecture space integrated control system was designed,which made a big increase in performance, power consumption, volume.The dual-core SoC chip inside the SiP chip was used to run the main control program and navigation control algorithm, and rich peripheral interfaces were realized through the interface resources integrated by the chip and the programmable logic resources.The hardware system design, software system design and structure design scheme of integrated control system were presented. The corresponding performance test showed that the system worked normally and all performance indicators met the mission requirements, which could be used for the future use of space vehicles.
