A verification method for non-along track imaging based on three axis air bearing table

摘要

In this paper, a non-along track imaging mode for remote sensing of satellite is introduced, and a ground experiment verification method is proposed, the feasibility of the control scheme is verified by mathematical simulation and physical experiment. The control requirements of satellite attitude in the non-along track imaging process are analyzed, based on the quaternion feedback control method proposed by Bong Wie, the attitude maneuver control law satisfying various constraints is given. By constructing a small three axis air bearing table control system and camera imaging system, the non-along track imaging scheme is verified. The experimental results show that the pointing control accuracy is better than 0.05 ° , the tracking accuracy of attitude angular velocity is better than 0.005 ° /s, and the imaging result of non-along track is good.
