Títol: Magnetic systems for the ADCS of a femtosatellite

Data inici oferta: 14-10-2022     Data finalització oferta: 14-05-2023



Estudis d'assignació del projecte:
    MU AEROSPACE S&T 15
    MU AEROSPACE S&T 21
Tipus: Individual
 
Lloc de realització: EETAC
 
Paraules clau:
femtosatellite, adcs, hysteresis, magnetorquer, magnetosphere
 
Descripció del contingut i pla d'activitats:
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 permanent magnets, 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 a permanent magnet and
the use of hysteresis rods. In order to add some control, a set
of magnetorquers will be designed.
