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 .

Classically, a gyroscope consists of a spinning mass, but there are also "ring laser gyros" utilizing coherent light reflected around a closed path. Another type of "gyro" is a hemispherical resonator gyro where a crystal cup shaped like a wine glass can be driven into oscillation just as a wine glass "sings" as a finger is rubbed around its ...
For example, the spinning rotor may be suspended in a fluid, instead of being mounted in gimbals. A control moment gyroscope (CMG) is an example of a fixed-output-gimbal device that is used on spacecraft to hold or maintain a desired attitude angle or pointing direction using the gyroscopic resistance force.
There were three control moment gyroscopes on Skylab, but only two were required to maintain pointing. [84] The control and sensor gyroscopes were part of a system that help detect and control the orientation of the station in space. [84] Other sensors that helped with this were a Sun tracker and a star tracker. [84]
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 ...
Demonstrated shuttle thermal protection repair techniques and enhancements to the Station's attitude control system. installed a base and cabling for an External Stowage Platform, rerouted power to Control Moment Gyroscope-2 (CMG-2), retrieved two exposure experiments, and replaced a faulty global positioning system antenna on the station.

The station's control moment gyroscopes (CMGs, or "gyrodynes") and main computer were shut down on 7 September, leaving Progress M-42 to control Mir and refine the station's orbital decay rate. [17] Near the end of its life, there were plans for private interests to purchase Mir, possibly for use as the first orbital television/movie studio.
