Abstract
Provided herein is a Coriolis vibratory gyroscope ('CVG'). The CVG includes a first plurality of actuators electrically coupled to the vibratory member and arranged about a drive axis of the CVG and operable to obtain a control signal from the controller and provide a voltage sufficient to cause and maintain the vibratory member to vibrate in a first mode of oscillation; a second plurality of actuators electrically coupled to the vibratory member and arranged about a sense axis of the CVG and operable to detect a voltage based on a second mode of oscillation of the vibratory member caused by a rotation of the CVG about an axis of rotation and to provide a counter-balancing signal sufficient to null the voltage based on the second mode of oscillation, wherein the controller is operable to determine a rate of the rotation of the CVG based, in part, on the counter-balancing signal.
