For the satellites launched into relatively low circular orbit (height of the orbit less then 400 km) aerodynamic satellite stabilization can be used. It orients the axis of symmetry of the satellite along the tangent to the orbit. Aerodynamic restoring torque in pitch and yaw is provided by a special very light stabilizer. To damp transient oscillations of the satellite one uses two single-degree-of-freedom gyros connected with the satellite body through a viscous-spring restraint. The gyro rotor is linked to the satellite through a damping device, and the oscillations of the satellite cause its precession producing dissipation of energy of oscillations of the satellite-gyros system. Moreover, the single degree-of-freedom gyros produce additional restoring torques in yaw and roll when the system deviates from its equilibrium orientation. The aerodynamic and the gyroscopic restoring torques are used to provide three-axis aerodynamic stabilization of the satellite. A similar aerodynamic stabilization system was installed in the Cosmos - 149 and Cosmos-320 russian satellites. Semipassive aerodynamic stabilization system can be used in small satellites to investigate physical processes in the atmosphere and to determine atmospheric parameters. Here some investigations of the attitude motion of small satellites with aerodynamic system are given.
