A gyroscope is a spinning wheel whose spin axis can move relative to some reference mount. For the sake of simplicity, the major components of the gyro are comprised of:
The Spin Motor, the main characteristic of which is "angular momentum".
The Gimballing System which is the structure carrying the spin motor. The gimballing system isolates the spinning rotor from the gyro-case if the gyro-case turns around the outer gimbal axis or if the gyro-case turns around the inner gimbal axis.
