JAXA has been developing Next Generation Star Tracker (STT). STT is the attitude sensor, which consists of hood, lenses, CCD, and some electric circuits. In acquisition mode, images of stars detected by CCD are compared with a star catalogue to determine the absolute orientation of a spacecraft without a-priori attitude information. STT is more accurate attitude sensor than earth sensor plus sun sensor system. Advanced Land Observation Satellite (ALOS) mounts large size Star Tracker to fulfill its high attitude accuracy requirement. On the other hand, we have been developing an autonomous Star Tracker whose size, power and mass is smaller than ALOS/Star Tracker., 資料番号: AA0049054046, レポート番号: JAXA-SP-05-008

This is the report of a study of high performance maneuver for artificial satellite. Especially, CMG (Control Moment Gyro) aiming to agile reorientation maneuver is discussed in this report. The number and the arrangement of the CMG cluster were examined, for Rest-to-Rest maneuvering. The performance presumption parameter to the first design estimate was derived. The CMG assembly design for agile maneuver is determined by requirement of angular momentum and the moment of inertia of satellite. The result of the CMG assembly arrangement should be discussed from the point of electrical energy consumption, precise weight estimation and cost., 資料番号: AA0049054045, レポート番号: JAXA-SP-05-008

科学衛星は、他の衛星と同様に、ミッションを達成するためにその姿勢を所望の方向へ制御する必要がある。最近の科学衛星においては、ミッションの高度化に伴い、姿勢制御系に対する要求も高まっている。本稿では、ミッション側からの要求をまとめ、それに対するJAXAとしての取り組みを紹介する。また、2004年度に再編された科学衛星専門研究委員会姿勢班の活動、および総合技術研究本部との協力体制について紹介する。, 資料番号: AA0049122100

Control technology of the Large Space Structure (LSS) is supposed to be one of the key technology in the future space activity, however, there are many problems which have not been solved. This research aims to solve such problems and to establish the basic technology of the LSS. In this research, Space Solar Power System (SSPS) is focused on as the very Large Space Structure, and the assembly and maintenance technique is studied. In this report, the result of this study in the FY2003 activity is described., 資料番号: AA0048129011, レポート番号: JAXA-RM-04-011

Results of research on large-scale, flexible space structures are reported. In this study, it is aimed to develop a lightweight inflatable structure by applying the thermoplastic composite. An inflatable tube is manufactured using a newly developed bundle of the thermoplastic composite. Through some experiments, the feasibility of its stowing, development, and rigidization are demonstrated. An innovative control system is also developed for the structural control of large and flexible structures. To accommodate the structural vibration of a very long period, the control system uses the fiber Bragg grating to measure the strain of the structure, and the piezo actuators to cancel the structural deformation. Architectures of distributed control systems are also discussed. Through experiments, the effectiveness of the control system is clearly demonstrated. Because these are promising fundamental technologies for the future spacecraft, it is important to continue the research and development and to have opportunities of space demonstration in the near future., 資料番号: AA0048129009, レポート番号: JAXA-RM-04-011

第58回宇宙科学技術連合講演会（2014年11月12日-14日. 長崎ブリックホール), 長崎市, 長崎県, "To realize advanced scientific satellites and earth observation satellites requiring more accurate pointing knowledge and higher angular-rate maneuver, we developed a precision autonomous star tracker for agile spacecraft, which is named as Autonomous Star Tracker NSTT (Next-Generation Star Tracker). NSTT realizes autonomous attitude determination without a priori information, keeps tracking stars under a satellite motion of up to 3 degrees/s, and provides high-accuracy attitude determination results. The formal qualification test of NSTT was completed in April 2014. Two flight models of NSTT have been manufactured and will be launched atop of the next X-ray observation satellite, ASTRO-H.This paper describes the technical challenges of NSTT and our solutions to them, summarizes the design and manufacture results of NSTT, and presents qualification test results of NSTT.", 資料番号: AC1500020000, レポート番号: JSASS-2014-4455
