This study describes the evaluation of on-orbit integrity and performance of high-torque reaction wheels. The on-orbit friction torques during Earth pointings and output torques during maneuvers are analyzed using the telemetry data to monitor the performance of the torques. The results of on-orbit data analyses show that these wheels maintain and execute desirable performances., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AC1600071000, レポート番号: JSASS-2015-4117}, publisher = {日本航空宇宙学会(JSASS), The Japan Society for Aeronautical and Space Sciences (JSASS)}, title = {ALOS-2搭載高トルクリアクションホイールの軌道上性能評価}, year = {2015} }
