Patent ID: 7481110

Claim:
A method for quadrature-bias compensation in a Coriolis gyro, whose resonator is in the form of a coupled system comprising a first and a second linear oscillator, in which the first oscillator is attached to a gyro frame of the Coriolis gyro by means of first spring elements and the second oscillator is attached to the first oscillator by means of second spring elements, having the following steps: determination of the quadrature bias of the Coriolis gyro, production of an electrostatic field, in order to vary the mutual alignment of the two oscillators with respect to one another, with the electrostatic field producing a constant electrostatic force which causes a change in the alignment of the first spring elements and/or a change in the alignment of the second spring elements, and with the alignment/strength of the electrostatic field being regulated such that the determined quadrature bias is as small as possible.
