Validation of Steering Law for a 4-Variable-Speed Single-Gimbal Control Moment Gyroscope Pyramid Cluster via Spherical Air-Bearing Testbed

Validation of Steering Law for a 4-Variable-Speed Single-Gimbal Control Moment Gyroscope Pyramid Cluster via Spherical Air-Bearing Testbed

• VSCMG: wheel speed is commanded with gimbal rate — the extra DOF lets the cluster slide past singularities.
• HIL: a Helmholtz cage replays the on-orbit field and a solar simulator sets the Sun line.
• This work: HIL validation of a weighted-pseudoinverse steering law, 4-unit pyramid.
