Abstract

This paper presents a control algorithm for three axis attitude regulation of a 2U CubeSat by means of gravity gradient and atmospheric torques. The inertia tensor of the spacecraft is modified to keep the spacecraft in a gravity gradient stable configuration. A Lyapunov-based control law acts simultaneously to improve the pitch angle regulation performance using atmospheric torque.
