Abstract

One example includes a resonator gyroscope (10). The resonator gyroscope includes a sensing system (12, 50) comprising a plurality of electrodes (18, 54, 56, 58, 60, 62, 64, 66, 68) arranged about a sensitive axis (70) and configured to electrostatically force a resonator (16) into a substantially periodic motion based on a plurality of forcer signals (FRC) applied to the plurality of electrodes (18, 54, 56, 58, 60, 62, 64, 66, 68), and configured to provide an indication of rotation (ROT) about a sensitive axis (70) of the resonator gyroscope (10). The resonator gyroscope (10) further includes a controller (14) configured to generate the plurality of forcer signals (FRC) to provide the substantially periodic motion of the resonator (16) concurrently in each of a plurality of separate vibration pattern modes to measure the rotation (ROT) of the resonator gyroscope (10) about the sensitive axis (70) in response to a plurality of pickoff signals (PO) associated with the substantially periodic motion.
