abstract = "This work is related to the dynamics of rotational motion of
artificial satellites, that is, its orientation (attitude) with
respect to an inertial reference system. The attitude
determination process, in general, involves the knowledge of
nonlinear estimation techniques and is essential to the safety and
control of the satellite and payload. The aim of this work is to
study the influence of real data of the CBERS-2 (China Brazil
Earth Resources Satellite) satellite in the attitude estimation
process when the estimator is the Unscented Kalman Filter (UKF)
and the attitude is represented by quaternion incremental. The
attitude sensors available are DSS (Digital Sun Sensor), IRES
(Infrared Earth Sensor), and the gyros. For nonlinear systems, the
UKF uses a carefully selected set of sample points to map the
probability distribution more accurately than the linearization of
the standard Extended Kalman Filter (EKF). Herein the proposal is
to estimate the attitude and the drift of the gyros obtained by
the UKF and EKF with quaternion incremental and compare them. The
results show that, although the EKF and UKF have roughly the same
accuracy, the UKF leads to a convergence of the state vector
faster than the EKF. This fact was expected, since the UKF
prevents the linearizations needed for EKF, when the system has
some nonlinearity in their equations.",
