Abstract
This report is the introduction of a study of SG-CMG (Single-Gimbal Control Moment Gyro) for agile satellite maneuver in JAXA IAT. In this research, the Rest-to-Rest satellite maneuver by 4-CMG is planned. The feature of the CMG test system is described. Control low of the pair drive of CMGs is explained. It aims to verification of agile artificial satellite maneuver by the experiment and the research of up to date is announced.
