Abstract: A scheme of three axis passivity stabilization realized by using two main environmental torque (aerodynamic torque and gravity gradient) for low orbit microsat is presented.Restore torque for pitch and roll orientation is provided by gravity gradient. Restore torque for yaw and pitch orientation is provided by aerodynamic torque.The attitude stability analyses are presented and the simulations are also provided.The result shows that the satellite has simple structure and excellent control precision.
