| Abstract: | The liquid slosh and the attitude dynamics of a three-axis stabilized satellite with offcentered liquid filled containers are investigated in the present paper.An equivalent mechanical model of liquid filled rigid body system has been set up. Using this model,the attitude stabolity of the satellite is investigated and a stability criterion when the attitude motion is constrained to pitching is obtained. |
