A control moment gyroscope (CMG) is an attitude control device generally used in spacecraft attitude control systems. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum .
Gyroscopic control may refer to: Control moment gyroscope , an attitude control device generally used in spacecraft attitude control systems Gyroscopic control (gaming) , accelerometers to as a control input
These are rotors spun at constant speed, mounted on gimbals to provide attitude control. Although a CMG provides control about the two axes orthogonal to the gyro spin axis, triaxial control still requires two units. A CMG is a bit more expensive in terms of cost and mass, because gimbals and their drive motors must be provided.
A gyroscope flywheel will roll or resist about the output axis depending upon whether the output gimbals are of a free or fixed configuration. An example of some free-output-gimbal devices is the attitude control gyroscopes used to sense or measure the pitch, roll and yaw attitude angles in a spacecraft or aircraft.

Gyroscopes failed on several occasions on the Hubble Space Telescope and had to be replaced several times. However, these were a different design called a gas-bearing gyroscope, which have certain benefits but experienced some long-term reliability issues. [39] JWST will have six gyroscopes, but only two are required for pointing. [38]
A Gyroscopic stabilizer is a control system that reduces tilting movement of a ship or aircraft. It senses orientation using a small gyroscope, and counteracts rotation by adjusting control surfaces or by applying force to a large gyroscope. It can be: Some active ship stabilizers adjust "active fins" of the ship or apply force to a large ...
The control panel for the Minneapolis-Honeywell C-1 gyroscopic autopilot, used on B-24 bombers. The gyroscopic autopilot was a type of autopilot system developed primarily for aviation uses in the early 20th century. Since then, the principles of this autopilot has been the basis of many different aircraft control systems, both military and ...
