| Summary: | This report describes the feasibility of attitude determination and control of the student satellite MIST. It investigates the stability and controllability of the satellite system, it covers attitude determination based on magnetometer and sun sensor measurements available and finally compares two controllers and the resulting pointing accuracy of the satellite. The study shows that the pointing requirements can be met under nominal circumstances. === I denna rapport utreds hur noggrannt en studentsatellits attityd kan uppskattas och kontrolleras. Sensorerna och aktuatorerna består av en magnetometer, tre magnetiska spolar och sex solsensorer. Mätningarna filtreras och används i två olika regleralgoritmer, följt av en jämförelse mellan resultaten av de båda metoderna. Rapporten visar att satellitens noggrannhetskrav på attityden kan uppfyllas under normala förhållanden. |
