 note = {第11回宇宙環境シンポジウム (2014年12月10日-11日. 大阪府立大学 I-siteなんば), 大阪, 11th Spacecraft Environment Symposium (December 10-11, 2014, I-site Namba, Osaka Prefecture University), Osaka, Japan, A low-orbit spacecraft receives large air drag because neutral atmosphere gets denser in lower earth orbit. A thermosphere model NRL-MSIS00 was establishes based on measurement data of neutral atmospheric density and it is currently used for spacecraft drag estimation. However, the model is unable to be applied to the super low Earth orbit because measurement of neutral atmospheric density at this altitude is difficult due to high density of air. In order to obtain neutral atmospheric density, an accelerometer is used to detect deceleration of spacecraft due to air drag. In the case of super low altitude air density estimation, highly sensitive and wide-range accelerometers that can detect 10(exp -8) - 10(exp -2) m/s2 is required. Thus a new type of accelerometers which consists of contactless optical displacement sensors and magnetic actuators that has enough controlling force is proposed. This research investigates of elemental technology of the new type accelerometer. An experimental model of the new type of accelerometer demonstrated detection of two-DOF acceleration. A six-DOF accelerometer extended from the two-DOF will be constructed., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530019007, レポート番号: JAXA-SP-14-012},
