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 ...
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
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.

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 ...
In January 2019, WorldView-4 was announced to have suffered a failure in one of its control moment gyroscopes, and was considered no longer usable. [9] WorldView-4 was insured against satellite failure, and in spring 2019 the company owning the satellite, Maxar Technologies , which had acquired DigitalGlobe in 2017, announced that they had ...
Artist's depiction of a pair of O'Neill cylinders Interior view, showing alternating land and window segments. An O'Neill cylinder (also called an O'Neill colony, or Island Three) is a space settlement concept proposed by American physicist Gerard K. O'Neill in his 1976 book The High Frontier: Human Colonies in Space. [1]
