ABSTRACT. ALL THE SATELLITES POSSESS COMPONENTES THAT CAN MOVE TO AND FRO, AS A LIQUID COMBUSTIBLE IN A TANK, OR TO OSCILLATE AS IF IT WAS A MASS-SPRING-DAMPER SYSTEM WITH DAMPING OR NOT. THOSE DISPLACEMENTS OR OSCILLATIONS PRODUCE OSCILLATIONS IN THE PROPER VEHICLE, DISTURBING ITS ATTITUDE (MOVIMENT AROUND THE MASS CENTER).
THE OBJECTIVE OF THIS WORK IS TO STUDY THOSE DISTURBANCES USING A MASS-SPRING-DAMPER SYSTEM TO SIMULATE THOSE VIBRATIONS AND TO QUANTIFY ITS EFFECTS IN THE SATELLITE ATTITUDE MOVIMENT, THAT MEANS, IN ITS ANGULAR VELOCITIES AND ATTITUDE ANGLES.
KEYWORDS: VIBRATIONS, MASS-SPRING-DAMPER, ATTITUDE
