摘要
微纳卫星组网应用可大幅度提高航天装备的能力,较单颗大卫星具有明显的优势。首先,介绍了国内外微纳卫星组网的研究情况,以组网侦察应用为例分析了星间测量与通信链路的技术需求,并进行了系统架构和体制设计;其次,在星座设计基础上开展系统仿真,并提出了一体化设备实现方案;最后,分析了微纳卫星组网系统中几项重要的关键技术及其解决方案,对系统的设计和工程实现具有参考价值。
The application of micro-nano satellite networking can highly improve the ability of astronautics equipment,which is obviously superior to single big satellite.Firstly,the research on micro-nano satellite at home and abroad is introduced,inter-sat measurement and communication link technological requirements are analyzed by taking networking reconnaissance application as example,and system architecture is designed.Secondly,system simulation is performed and integrated equipment realization scheme is proposed.Finally,several key technologies for micro-nano satellite networking system are analyzed,which has reference value for particular system design and engineering realizition.
