    摘要： 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.

    摘要： A vibration-type angular velocity sensor (100) includes a first angular velocity sensor unit (101) and a second angular velocity sensor unit (102). In a predetermined period, the second angular velocity sensor unit performs a process of detecting an angular velocity based on secondary vibration of a vibrator (11) by a secondary side control circuit (17) and a process of detecting the angular velocity based on the secondary vibration of the vibrator by the primary side control circuit (16) by interchanging functions. The first angular velocity sensor unit detects the angular velocity in the predetermined period. The bias component of the first angular velocity sensor unit is calculated based on a first detection result detected by the first angular velocity sensor unit in the predetermined period and a second detection result detected by the second angular velocity sensor unit in the predetermined period.

    摘要： The present invention is concerned with a method of calibrating a vibrating gyroscope. The method comprises exciting a vibration along an excitation axis of a resonant structure wherein the excitation axis is positioned at a first angular position, sensing the vibration of the resonant structure on a first sensing axis of the resonant structure while the excitation axis is positioned at the first angular position, generating a first sensing signal indicative of the sensed vibration of the resonant structure on the first sensing axis, rotating the excitation axis in a continuous manner around the resonant structure to a second angular position, sensing the vibration of the resonant structure on a second sensing axis of the resonant structure while the excitation axis is positioned at the second angular position, generating a second sensing signal indicative of the sensed vibration of the resonant structure on the second sensing axis and adding the first sensing signal to the second sensing signal in order to derive a bias of the gyroscope.
