Abstract:The attitude information of spacecraft can be obtained by the sensors attached to
it using a star tracker, three-axis magnetometer, three-axis gyroscope, and a global
positioning signal receiver. By using these sensors, the spacecraft can be maneuvered by
actuators that generate torques. In particular, electromagnetic-torque bars can be used
for attitude control and as a momentum-canceling instrument. The spacecraft momentum can
be created by the curr… Show more
