Abstract
A gyroscope is driven at a drive frequency and senses a Coriolis force caused by rotation of the gyroscope. The response of the gyroscope to a given Coriolis force may change due to changes in the gyroscope over time. A plurality of test frequencies are applied to the gyroscope, and the response of the gyroscope to those test frequencies is analyzed in order to track changes in the response of the gyroscope. Operational parameters of the gyroscope may be altered in order to compensate for those changes.
