Reaction wheels configuration
Did you know?
WebThe reaction wheel exchanges momentum with the spacecraft body by accelerating or deccelerating the wheel, changing the wheel momentum magnitude, while the control moment gyroscope reorients the wheel, changing the wheel momentum direction (variable speed control moment gyroscopes are capable of both, and have many advantages). A reaction wheel (RW) is used primarily by spacecraft for three-axis attitude control, and does not require rockets or external applicators of torque. They provide a high pointing accuracy, and are particularly useful when the spacecraft must be rotated by very small amounts, such as keeping a telescope pointed at a … See more Reaction wheels are used to control the attitude of a satellite without the use of thrusters, which reduces the mass fraction needed for fuel. They work by equipping the spacecraft with an electric … See more For three-axis control, reaction wheels must be mounted along at least three directions, with extra wheels providing redundancy to the attitude control system.
