中文摘要：
为检验“微型核”航天器设计平台的功能,对星载电子系统进行优化设计.采用主流的SoC设计方法,通过功能模块化映射将ARM7内核,C8051单片机、RFIC射频模块等单元模块集合为一体,借助软件设计平台,形成了具有丰富I/O接口,高处理速度的星载电子系统原理样机.在与哈尔滨工业大学TS-1星载计算机的功能对比中,“微型核”星载电子系统出色的完成了星务管理、数据采集传输,姿态轨道控制等多种任务,控制精度满足任务要求.结果表明基于SoC的星载电子系统有能力替代现有的星载计算机成为未来微型航天器的核心.
英文摘要：
To validate the functions of general cell spacecraft design platform and the methodology of designing on-board electronic systems based on SoC, a design of the on-board electronic system is demanded. The design has integrated the fashionable modules including ARM7, C8051 and RFIC together into a prototype that possesses redundant I/O interfaces and high-performance on computing. Compared with Ts-1 launched by Harbin Institute of Technology, the prototype achieves the same excellent performance by implementing multiple tasks such as satellite housing, data processing as well as attitude and orbit controlling. The result reveals that the designed prototype is capable of taking the core place of the present on-board computer in the days ahead.
