Dual suspension gyroscopic device having powered gimbal support

A dual suspension gyroscopic device includes a gyro having at least a single degree of freedom and defining an output axis, i.e., the sensitive axis of the gyroscopic device. The gyro is supported by a gimbal which in turn is supported in a case for unlimited angular displacement about the gimbal axis. The arrangement provides low torque suspension about the sensitive axis while permitting normal angular displacement about said axis and maintaining the gyro spin axis in a reference plane. A data transferring slip ring assembly is arranged with the gimbal support and the slip ring assembly and support arrangement is powered to minimize friction about the gimbal axis.
