Attitude Control
Attitude control is the system that keeps a spacecraft oriented correctly in space, pointing its instruments or antennas in the right direction.
TECHNICAL DEFINITION
Attitude control is the process of maintaining or changing the orientation of a spacecraft or aircraft relative to an inertial frame or another entity, typically using reaction wheels, thrusters, or magnetorquers to achieve desired pointing accuracy for sensors, antennas, and solar arrays.
BACKGROUND
Bigelow Aerospace was an American space design and manufacturing company which ceased operations in 2020. It was an aeronautics and outer space technology company which manufactured and developed expandable space station modules. Bigelow Aerospace was founded by Robert Bigelow in 1998, and was based in North Las Vegas, Nevada. It was funded in large part by the profit Bigelow gained through his ownership of the hotel chain Budget Suites of America.
