Popis:	Japan Aerospace Exploration Agency (JAXA) 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 every JAXA satellite. It has passed over 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, we decided to redesign IRU. Aiming is high-reliability and high-accuracy. The study has started in FY2001. In FY2005 IRU redesign was completed and we prepared every document needed for Flight Model (FM) production. 資料番号: AA0049500078 レポート番号: JAXA-SP-06-006
