Unscented Kalman filter for spacecraft attitude estimation using modified Rodrigues parameters and real data
(2016-10-01)
In this paper, a sigma-point Kalman filter formulation for attitude estimation is derived using the modified Rodrigues parameters and real data of attitude sensors. The unscented Kalman filter algorithm is used for attitude ...

Low cost attitude estimation system. Performance evaluation on an airbearing based testbed
(Universidad de Buenos. Facultad de Ingeniería, 2015)
In this work, a low-cost attitude navigation system for spacecrafts is presented. The system fuses measurements from a three axis MEMS gyroscope and a CCD camera that identifies a known pattern of points (which emulate the ...
Unscented Kalman Filter Applied to the Spacecraft Attitude Estimation with Euler Angles
(Hindawi Publishing Corporation, 2012-01-01)
The aim of this work is to test an algorithm to estimate, in real time, the attitude of an artificial satellite using real data supplied by attitude sensors that are on board of the CBERS-2 satellite (China Brazil Earth ...
