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
