Global Attitude Acquisition of Spacecraft by Reaction Wheel

  

  • Online:2014-10-23 Published:2014-10-28

Abstract: Global attitude acquisition (GAA) refers to an attitude control process of recovering the norminal attitude or a new orientation, when a spacecraft loses attitude reference. To overcome the deficiencies of traditional GAA using thruster system or magnetic torquer as main actuator, which costs fuel consumption or more recapture time, a method of GAA based on reaction wheel is proposed here. By using the conventional configuration of the spacecraft, this method can realize orientation to any space target, and is proved to be efficient, good at engineering operation by onorbit results.

Key words: reaction wheel, global attitude acquisition, attitude control, onorbit demonstration
