A 3-axis attitude control system hardware design for a CubeSat

[摘要] ENGLISH ABSTRACT: With CubeSats becoming popular as a cheap alternative to larger satellites, the needfor advanced miniature attitude determination and control systems (ADCS) arises tomeet the pointing requirements of satellite operations such as earth imaging and orbitmaintenance. This thesis describes the design of a complete ADCS for use on CubeSats.A previously designed CubeSat on-board-computer, CubeComputer, andne sun andnadir sensor, CubeSense, is incorporated in the design. The remaining requirements withregard to sensors and actuators were met by CubeControl, an additional module, thedesign, manufacturing and testing of which are described. CubeControl can implementmagnetic control with the use of a magnetometer and three magnetorquers. It is alsocapable of driving three reaction wheels for accurate active 3-axis stabilization.
