abstract = "This paper presents the attitude estimation using Kalman filter,
the PID control strategy and the momentum dumping technique using
magnetorquers for the Brazilian satellite CONASAT. Attitude will
be represented in quaternions, so the Kalman filter will be
implemented using the reduced order covariance, to avoid the
singularity of the covariance matrix. The reaction wheel
desaturation will be made using the Conventional Cross Product Law
(CCPL) and a bang-bang strategy, for comparison by means of the
magnetorquers. The results show that the Kalman filter estimates
correctly the gyroscope bias, allowing the PID controller to keep
the attitude error below 5°, even during the satellite passage
through the Earths shadow. The wheels speed decreased to the
reference value (zero) in about 4500s, using either CCPL or the
bang-bang strategy.",
