摘要
本文对世界首颗独立完成地月转移、近月制动、环月飞行的微卫星"龙江二号"进行了介绍。首先阐述了龙江二号的任务目标和总体方案;然后重点分析了轨道设计与控制、复杂电磁干扰的标定与抑制、宽视场三维基线干涉测量等关键技术难点;接着回顾了任务的实施过程;最后详细介绍了低频射电探测仪、沙特光学相机和VHF/UHF通信模块与学生微型CMOS相机等有效载荷,并展示了上述载荷获取的初步成果。
Longjiang-2,the world’s first microsatellite that completed lunar transfer,lunar insertion and lunar orbiting independently,is introduced in this paper.Firstly,the mission objects and design overview of the microsatellite are expounded.Then,the technical difficulties of the microsatellite,including orbit design and control,measurement and suppression of onboard electromagnetic interference,and wide-field 3 D baseline interferometry,are analyzed.In addition,the implementation process of the mission is reviewed.Finally,the onboard payloads,including the low frequency radio interferometer,the Saudi optical camera,the VHF/UHF radio and the student CMOS camera,are elaborated;Moreover,the flight results of the onboard payloads are presented.
