Research on Very Small Satellite Design and Development

本研究的目的是通过高校小卫星实验开发的努力，建立小卫星的设计和开发程序，积累相关技术，培养有经验的空间开发工程师。在四年的研究过程中，九州大学和东京大学这两所合作大学通过各自的努力，朝着这些目标取得了实质性的进展。九州大学建立了演示系绳技术的50公斤级卫星的系统架构和关键技术要素。另一方面，东京大学把精力集中在一颗非常小的1公斤卫星上，并验证了它在轨道上运行的能力。这些任务是在密切的技术交流和采用共同技术要素的情况下完成的，以便促进相互研究的合作，避免重复投资。两所大学已成立大学空间工程联盟，进一步加强合作。这被认为是一个重要的成果，将合作扩大到全国范围的运动，受到目前合作研究工作的启发。

The purposes of this research are to establish design and development procedures of small satellites, to accumulate related technologies, and to bring up experienced engineers in space development, through efforts of experimental development of small satellites in universities. During the four-year pursuit of this research, the partner universities, Kyushu University and Tokyo University, made substantial progress toward these purposes, through efforts toward respective goal adopted by each university.Kyushu University established system architecture and critical technology elements of 50 kg class satellite that demonstrates tether technology. Tokyo University, on the other hand, focused its effort to a very small 1 kg satellite and verified its capability to operate in orbit. These tasks were done under close technical exchanges and adoption of common technical elements, in order that collaboration of mutual research may be facilitated and overlapping investment may be avoided.Collaboration between two universities has been further strengthened by establishment of the University Space Engineering Consortium. This is considered to be an important outcome, by expanding collaboration to nation wide movement inspired by the present collaborative research work.
