 note = {Japan Aerospace Exploration Agency (JAXA), formerly named as National Space Development Agency (NASDA), developed Tuned Dry Gyroscope (TDG), as supreme precision rate sensor for satellite attitude control. JAXA also developed Inertial Reference Unit (IRU) using TDG. This IRU is used on almost every JAXA satellite. It has passed about fifteen years since the development. It is difficult to purchase some kind of electronics parts nowadays. Meanwhile, satellite system requires higher accuracy, more operation flexibility and so on. So, it was decided to redesign IRU. Aiming is high-reliability and high-accuracy. The study has started in FY 2001. In FY 2003 IRU redesign was completed. Prepared was every document needed. In FY 2004, an engineering model is built and its function and performance are qualified. In FY 2005, this study will be completed., 資料番号: AA0048057004, レポート番号: JAXA-RM-04-010},
