Attitude control of a spacecraft using two SGCMGs
This thesis presents new methods for controlling spacecraft using Control-Moment Gyros (CMGs). CMGs generate torque to change and maintain a spacecraft's orientation. The CMG control system is used specifically to provide three-axis altitude stabilization, precision pointing control and …
