Abstract
A gyroscope system including multiple rotating or oscillating disks filters out disturbance acceleration inputs such as vibrations or jarring while detecting and measuring external angular velocity. The gyroscope disks are decoupled from a substrate to decrease the impact of external vibrations on the gyroscope operation. The gyroscope disks are rotated in opposite directions or oscillated out of phase to decrease the impact of disturbance vibrations and jarring while more accurately measuring external angular velocities applied to the system.
