Attitude Dynamics of Spinning Magnetic LEO/VLEO Satellites

With the growing popularity of small satellites, interaction with air in low and especially very Earth orbits becomes a significant resource for passive angular stabilisation. However, possibility spin motion remains considerable challenge missions involving aerodynamically stabilised satellites. The goal this paper was to investigate attitude arbitrarily spinning satellites LEO VLEO under action aerodynamic, gravitational, magnetic torques, taking into account aerodynamic damping. Using an umbrella-shaped deployable satellite as example, study demonstrated that both regular chaotic regimes are possible motion. occurrence chaos verified by means Poincaré sections. results revealed that, prevent motion, active control reliable deployment techniques needed.
