Abstract
A rotational rate gyroscope ( ) for detecting rotation thereof comprises a base member ( ), a primary oscillator ( ) supported by its primary oscillator suspension ( ) so as to be movable with respect to the base member ( ), and a secondary oscillator ( ) supported by a secondary oscillator suspension ( ), separate from primary oscillator suspension ( ), so as to be movable with respect to the primary oscillator ( ). The secondary oscillator suspension ( ) is designed such that movement that can be applied to the primary oscillator ( ) can be transferred to the secondary oscillator ( ), whereas the movement of the secondary oscillator ( ) effected by the Coriolis force substantially is not transferred back to the primary oscillator ( ). In addition thereto, the major surfaces of the primary oscillator ( ) and of the secondary oscillator ( ) extend substantially in the same plane, with the movement of the primary oscillator ( ) and/or of the secondary oscillator ( ) also taking place in this plane.
