1. A gyroscope for determining a rotation rate, comprising:

  • a drive frame springedly coupled to a base of the gyroscope;

    a drive structure configured for causing a drive frame of the gyroscope to oscillate; and

    control circuitry configured for;

    determining an amplitude of the oscillation of the drive frame,comparing the amplitude to a setpoint, andadjusting the oscillation of the drive frame based on the comparing of the amplitude and the setpoint.
