Abstract

A sensor is disclosed for detecting a rotational motion about a resulting sensitivity axis. The sensor includes at least two dual mass gyroscope units, each of the gyroscope units are adapted to detect a rotational motion about a sensitivity axis of the respective gyroscope unit. The sensitivity axes being parallel to each other and to the resulting sensitivity axis. The gyroscope units are interconnected at the inertial masses of the gyroscope units which cause the gyroscope unit to operate synchronously.
