Abstract
Gimbal ring 32 has torquer positioner 34 and position detector 36 connected by servo loop 38, 40. Vibration sensor 52 on ring 32 provides ring vibration signals to amplifier shifter 54, 58 and the resultant signals are added to the servo loop at amplifier 40 to damp out the detected vibration.
