A new scheme of attitude control with active magnetic torque and aerodynamic stabilization torque was proposed for low-orbit micro-satellite (orbit altitude lower than 500km), in order to take full advantage of environmental torque. Simulation results show that the characteristic distance of satellite d_cc is the linchpin which influences the attitude control scheme. Suitable magnitude of d_cc should be chosen in order to meet the request of satellite attitude control system. All this shows that the satellite structure proposed in the current study has the potentiality of being used for experimental teaching and research.
