abstract = "A spacecraft attitude estimation approach based on the Unscented
Kalman Filter is derived. For nonlinear systems the Unscented
Kalman Filter uses a carefully selected set of sample points to
map more accurately the probability distribution than the
linearization of the standard Extended Kalman Filter, leading to
faster convergence from inaccurate initial conditions in attitude
estimation problems. The filter formulation is based on standard
attitude-vector measurements using a gyro-based model for attitude
propagation. This paper compares the performance of a new
technique, the Unscented Kalman Filter, when two different
mathematical constructs are used to represent the attitude: the
Euler angles and quaternions. In this study, the attitude of
satellite is estimated with real time algorithms using real data
supplied by gyros, Earth sensors and Sun sensors that are on board
of the CBERS-2 (China Brazil Earth Resources Satellite).",
