Spin-stabilized satellite with Sun-pointing active magnetic attitude control system
Abstract:
The angular motion of an axisymmetrical satellite equipped with the active magnetic attitude control system is considered. Dynamics of the satellite is analytically studied on the whole control loop. Two coarse sun-pointing algorithms and nutation damping are studied. Fine sun-pointing algorithm is implemented last. Two different algorithms are proposed. Active magnetic attitude control system time-response with respect to its parameters is analyzed, orbit inclination is of particular interest. Numerical simulation is carried out.
