摘要： The method and apparartus in one embodiment may have the steps of: providing a two-dimensional axisymmetric oscillator having a beam containing two principal elastic axes and two principal damping axes; driving the beam with drive components to oscillate; driving, during a first period, the beam along a drive axis of the beam in a direction normal to one pair of faces of the beam while Coriolis coupled vibration is sensed along a sense axis of the beam normal to an orthogonal pair of faces of the beam; reversing, during a second period, drive and sense axes driving the beam; reducing a bias of the beam to zero; and reducing a quadrature of the beam to zero.

摘要： An exemplary vibrating mass gyroscope uses a mass disposed for movement along an x-axis and y-axis. First and second electrodes are disposed adjacent surfaces of the mass along an x-axis and y-axis. Circuitry, coupled to the first and second electrodes, provides during a first mode a dither driving voltage on one of the first and second electrodes causing vibrating displacement of the mass along the one of the x-axis and y-axis. The measurement voltage is sensed on the other of the first and second electrodes where the measurement voltage represents a first angular rate value. During a second mode, the circuitry provides a dither driving voltage on the other of the first and second electrodes causing vibrating displacement of the mass along the other of the x-axis and y-axis and measurement voltage is sensed on the one of the first and second electrodes where the measurement voltage represents a second angular rate value. A combiner coupled to the circuitry receives the first and second angular rate values, and generates a resulting angular rate value based on both the first and second angular rate values wherein common bias errors are canceled. The common bias errors cancel because the pickoff sensing axis is coincident with the forcing axis when the same electrode is used for both the forcing and for the pickoff.
