ABSTRACT:
A dynamically tuned free rotor gyro is equipped with a set of three case-fixed torquers equally spaced circumferentially about the drive axis beneath the rotor. Three pickoffs are arranged diametrically opposite the corresponding torquers beneath the rotor. The outputs of the three pickoffs are combined to produce a vector rebalance signal, which is nulled by the effect of the torquers. The vector rebalance signal is resolved into three separate control signals for the corresponding torquer drive circuits.
