Tolong jelaskan mengenai Giroskop kendali momentum

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.

Georgia Tech's Panagiotis Tsiotras has studied variable-speed CMGs in connection with flywheel energy storage and has built a spacecraft simulator based on them: faculty page

Virginia Tech's Christopher Hall has built a spacecraft simulator as well: faculty page

Texas A&M's John Junkins and Srinivas Vadali have written papers on VSCMGs for use in singularity avoidance: faculty page

Cornell's Mason Peck is researching CMG-driven nanosats with the Violet spacecraft: Violet project page

Space Systems Group at the University of Florida under Prof. Norman Fitz-Coy have been researching on the development of CMGs for pico- and nano-satellites and on various steering logics for singularity avoidance SSG

Professor Brij Agrawal at the Naval Postgraduate School has built two spacecraft simulators, at least one of which uses CMGs:

Honeywell Defense and Space Systems performs research in Control Moment Gyros  They also have developed a spacecraft simulator driven by CMGs: CMG Testbed Video

Naval Postgraduate School's Marcello Romano has studied variable-speed CMGs and has developed a mini single gimbal control moment gyro for laboratory experiment of spacecraft proximity maneuvers faculty page
