Abstract

A gyroscope including a mass capable of movement due to excitation and a mass capable of movement due to detection, a mechanism applying an excitation signal to the excitation mass in a first direction, a mechanism detecting the movement of the detection mass in a second direction orthogonal to the first direction, a mechanism detecting the movement of the excitation mass in the second direction, and a processor processing detection signals emitted by the mechanism detecting movements of the detection mass and the mechanism detecting movements of the excitation mass in the second direction, to obtain a phase bias, quadrature bias, and amplification factor.
