Abstract
A ring gyroscope which comprises a substantially circular and flexible ring which defines a ring plane, one or more primary piezoelectric split transducers configured to drive the ring into resonance oscillation, four or more mass elements which form a symmetrical mass distribution in relation to both a first and a second transversal symmetry axis and to a first and a second diagonal symmetry axis. The ring gyroscope also comprises a suspension structure configured to support the weight of the ring and the mass elements, wherein the suspension structure comprises N outer suspenders, where N is an integer greater than or equal to two, and each outer suspender extends along a ring tangent from a suspension attachment point on the outer edge of the ring to an anchor point.
