A vibratory angular rate sensor includes a vibrating element instead of a rotating element as in gyroscopes. The vibratory sensor can withstand high accelerations, has long operating life, and is not costly. A new configuration for a vibratory sensor is proposed and analyzed. The proposed scheme has high mechanical gain and low sensitivity to changes in its parameters. An experimental prototype was built and tested, and the results show good agreement with the analysis.
