Abstract

A method for determination of the zero error of a Coriolis gyro. Appropriate disturbance forces are applied to the resonator of the Coriolis gyro such that at least one natural oscillation of the resonator is stimulated that differs from the stimulating and read oscillations. A change in a read signal which represents the read oscillation and results from the stimulation of the at least one natural oscillation is determined as a measure of the zero error.
