Study of Resonant Modes of Cubesat Nanosatellite Motion under the Influence of the Aerodynamic Moment

This paper considers the space motion relative to the center of mass of a CubeSat nanosatellite on a low circular orbit under the aerodynamic moment. The possibility of resonant modes of motion due to their inherent form factor of a rectangular parallelepiped and the presence of a small mass asymmetry (a transverse displacement of the center of mass from the axis of symmetry) is analyzed. We obtained the formulas for determining the critical value of the longitudinal angular velocity of a nanosatellite, at which the conditions for the appearance of resonances are satisfied. It is also shown the possibility of a roll resonance when the nanosatellite faces the incoming stream with one side edge and the average angular velocity of its own rotation is close to zero.
