1. A rebalance loop for a dry tuned rotor gyroscope having a rotor moveable about two orthogonal axes, means associated with one of said axes for producing an electrical error signal when a rate is applied to said one of said axes, means associated with the other of said axes for producing an electrical error signal when a rate is applied to said other of said axes, first means responsive to a first torque control signal for applying a torque to said rotor about one of said axes for restoring said rotor to a null position about said one of said axes and second means responsive to a second torque control signal for applying a torque to said rotor about the other of said axes for restoring said rotor to a null position about said other of said axes and said rebalance loop comprising:

  • first direct-axis circuit means responsive to one of said error signals for producing a first rate proportional torque signal and delivering said first rate proportional torque signal to said first means;

    second direct-axis circuit means responsive to the other of said error signals for producing a second rate proportional torque signal and delivering said second rate proportional torque signal to said second means;

    first cross-axis circuit means responsive to said one of said error signals for producing a first acceleration proportional torque signal and delivering said first acceleration proportional torque signal to said second means; and

    second cross-axis circuit means responsive to said other of said error signals for producing a second acceleration proportional torque signal and delivering said second acceleration proportional torque signal to said first means.
