Air bearing is a functional test infrastructure for satellite Attitude Determination and Control Subsystems (ADCS). Its working procedure and frictionless movement simulates the zero-g condition which Satellite experience in the orbit. By using this, satellite is capable to rotate around 3 axis roll, pitch and yaw.
Air bearing is necessary to evaluate the ADCS Algorithms and Softwares. Also, the performance of Actuators and sensors of the satellite can be tested in real situation to minimize the risk of error.
