Reaction wheels configuration
WebMar 15, 2010 · The satellite reaction wheel’s configuration plays also an important role in providing the attitude control torques. Several configurations based on three or four reaction wheels are investigated in order to identify the most suitable orientation that consumes a minimum power. WebABSTRACT The purpose of this paper is to identify the low-power Reaction Wheel ( RW) configuration for a 3-axis satellite attitude control at high and middle inclination orbits. All of the proposed R W configurations are evaluated through the numerical simulations with respect to an identical reference mission.

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.
