Magnetic systems for the ADCS of a femtosatellite

Magnetic attitude control systems are suitable for very small satellites, and yet provide a simple and robust method to detumbling and attitude control.

Resumo:Magnetic attitude control systems are suitable for very small satellites, and yet provide a simple and robust method to detumbling and attitude control. In this work we analyse the use of hard ferromagnetic materials and magnetorquers to control the attitude of a spherical femtosatellite. The model will propagate the orbit of the satellite (disregarding the effects of the atmosphere) by means of SGP4 or SGP8. Once the orbit is propagated, we will use a suitable model of the geomagnetic field (IGRF13 or WMM) to determine the magnetic field in the location of the satellite. Passive ADCS will be obtained by means of the use of hysteresis rods. In order to add some control, a set of magnetorquers will be designed.
