Three-Flywheel Assembly for Reduction of Attitude Jitter in Satellites
Multiple Flywheels Ensure Spacecraft Remain Functional if One or Two Flywheels FailThis three-flywheel assembly reduces attitude jitter caused by momentum actuators in satellites, improving its on-orbit pointing stability. Spacecraft with momentum actuators suffer form attitude jitter and high frequency oscillations due to imbalance in the rotors of...
