Taking Advantage of Geomagnetic Storms for B-Dot Attitude Control in Small Satellites.

The geomagnetic field models are presented with the external field influences taken into account. Magnetometers detect the external field, although most geomagnetic field models do not account for it. It is crucial to take into account how the external field affects the small satellite's other components. Furthermore, variations in the external field have the ability to affect the satellite's orbit and modify the spacecraft's drag, which could result in an altitude decrease and, eventually, mission failure. Consequently, to guarantee a successful mission, a comprehensive comprehension of the external field's influence on the small satellite's subsystems is required. In this work, the magnetorquers apply the magnetic control during the nanosatellite's detumbling phase. Although magnetic control cannot achieve three-axis control instantaneously, it can in near-polar trajectories due to the continuous variation of the magnetic field. In order to determine whether the geomagnetic storms may be exploited to our advantage by producing greater field variations, this study focuses on the extent to which it contributes to the magnetic control of the small satellites.
