Abstract
A vibrating gyroscope includes a proof mass (); a spring suspension system () for suspending the proof mass; an electrical drive mechanism for vibrating the proof mass along a drive axis (x); and electrodes () for building together with at least a part of the proof mass () a capacitance system for detecting moves of the proof mass along a sense axis (z) perpendicular to the drive axis. The gyroscope is arranged so that quadrature forces generate displacements of the proof mass without substantially displacing the neutral point () of the proof mass along the sense axis (z). This may be achieved by tilting the proof mass while keeping its neutral point at a constant position along the sense axis, or by applying a constant electrostatic force.
