Aerodynamic Torque exhibits non –resonance oscillation in satellite motion (original) (raw)

This paper deals with the non-linear oscillation of a satellite in an elliptic orbit around the Earth under the inuence of aerodynamic and gravitational torque. It is assumed that the orbital plane coincides with the equatorial plane of the Earth. Using BogoliubovKrylovMitropolsky (BKM) methods of nonlinear oscillations, it is observed that the amplitude of the oscillation remains constant up to the second order of approximation. Numerically time series, 2D and 3D phase spaces are plotted for Earth Moon system using Matlab. The existence of main and parametric resonance concludes the dierent frequency states which transit the motion from regular to an attractor that leads to chaotic state.
