摘要
文章研究的目的是针对目前智能手机技术的飞速发展,开展智能手机商用货架技术在低成本卫星上的应用前景研究。结合目前美国宇航局和英国萨瑞公司先后发射的手机卫星,将手机相关先进技术应用到航天任务中,开展了智能手机中央处理器技术、数字射频技术、导航芯片和能源管理技术等最新进展调研,并与当前航天使用的相关技术进行对比,对其在卫星上的应用前景进行了分析。通过分析得出结论:开展智能手机先进技术在卫星上的应用,重点要突破智能手机商用货架技术在卫星上的应用研究。通过对合格的商用货架器件进行进一步的评价筛选,开展热真空温度环境测试、寿命试验、结构分析、抗辐照评估后,确定该器件能否适用于空间卫星研制。最终得出研究结论:智能手机使用的商用货架技术在低成本卫星上的应用,对于提高卫星产品的技术水平具有重要的创新意义。
In this paper,the prospects of COTS technology of Smartphone used in low cost satellite are studied.The development of navigation chip,digital RF technology, power management and central processor technology was investigated and its prospect was analyzed so as to apply cell phone technology in space mission as several cell phone satellites have been launched by NASA and sari INC of Britain. The key of study lies on the breakthrough of application of commercial intelligent cell phone COTS technology(commercial off-the-shelf) on satellites.Through thermal vacuum test,assessment of anti irradiation,life span test and structure analyze, the feasibility of commercial components on shelf could be acquired. The application of intelligent cell phone technologies on satellites has significance on the improvement of satellite technology.
