Iss control moment gyroscope
WitrynaControl-moment gyroscopes (CMGs) have been used for attitude control on spacecraft that require large torques. A CMG consists of a spinning rotor and one or more motorized gimbals that tilt the rotor’s angular momentum. As the rotor tilts, the changing angular momentum causes a gyroscopic torque that rotates the spacecraft. WitrynaMotion Control Subsystem _____ The International Space Station (ISS) control system is composed of Russian and U.S. segments that maintain attitude control. When the Russian segment is in control, it uses attitude thrusters, which burn propellant. When the U.S. segment is in control, Control Moment Gyros (CMGs), manufactured by L3 ...
