摘　　要：神舟七号(SZ-7)载人航天任务中释放的一颗微小伴随卫星(BX-1),首次开展了卫星在轨释放、对飞船观测和对轨道舱接近及绕飞等技术试验.该卫星首次进行了GaInP2/GaAs/Ge中国产太阳电池阵、锂离子蓄电池、微型液氨推进模块、小型化姿态跟踪控制模块、双焦距一体化可见光相机及小型化USB测控应答机等技术验证.本文介绍了SZ-7微小卫星的设计方案,讨论了形成稳定伴随飞行的轨道设计等技术,并根据卫星在轨运行情况对试验任务进行了评价.The BX-1 micro-satellite, successfully released from the Shenzhou-7 （SZ-7） module, accomplished the purposes of providing the images of the SZ-7 and demonstrating the ability to inspect the orbital module and conduct proximity operations around the SZ-7 module. The BX-1 was a demonstrator for many new space technologies, including GaInP2/GaAs/Ge solar cells, lithiumion battery, micro-ammonia thruster, micro-attitude tracking controller, camera with double-focusing systems and micro-USB-responsor. The criterion of forming the stable elliptic orbit around the SZ-7 module is discussed in this paper. The evaluation of the BX-1 micro-satellite mission is provided by flight datum.
