Paper Abstract

This paper shows the use and capability of magnetic desaturation for momentum management of relatively low altitude orbiting satellites. A multi-dipole model is presented which is a convenient representation of the Earth's magnetic field. An analytic representation of desaturation capability is derived that is intended for the sizing of magnetic systems. A unique method of magnetic desaturation is presented that uses the full capability of the magnetic system actuators. Simulation results are presented that show the effectiveness of employing this magnetic desaturation method on a satellite subjected to various external disturbances. These results are then compared to the results predicted by the analytical method.
