NASA personnel handle a single Control Moment Gyroscope for the International Space Station.

Sebuah giroskop kontrol momentum atau control momentum gyroscope (CMG) adalah perangkat kontrol sikap umumnya digunakan dalam sistem kontrol sikap pesawat ruang angkasa. Sebuah CMG terdiri dari rotor berputar dan satu atau lebih gimbal bermotor yang sudut rotor momentum miring. Sebagai rotor miring, momentum sudut berubah menyebabkan torsi gyroscopic pesawat ruang angkasa berputar.
