Abstract
Suspension stiffness about the input axis of a gyro is increased by selectively disabling suspension legs when the gyro float exceeds a predetermined deviation away from the equilibrium position. Float position may be measured directly or inferred from monitoring currents in the electromagnetic suspension system. Suspension legs are re-energized when the float returns to within the predetermined deviation from the equilibrium position.
