Abstract
A navigation system includes a Coriolis vibratory gyroscope, a voltage input supply, and a controller. The voltage input supply is configured to supply a first voltage input to the Coriolis vibratory gyroscope at a first bias voltage, and supply a second voltage input to the Coriolis vibratory gyroscope at a second bias voltage, the second bias voltage being different than the first bias voltage. The controller is configured to detect a difference in responses of the Coriolis vibratory gyroscope to the first bias voltage and the second bias voltage, and determine a gyro rate of the Coriolis vibratory gyroscope as a function of the difference in responses and a correction term.
