| Resumo | This work is applied to the dynamics of rotational motion of artificial satellites, that is, its orientation (attitude) with respect to an inertial reference system. The attitude determination involves approaches of nonlinear estimation techniques, which knowledge is essential to the safety and control of the satellite and payload. Here one focuses on determining the attitude of a real satellite: CBERS-2 (China Brazil Earth Resources Satellite). This satellite was launched in 2003 and were controlled and operated in turns by China (Xian Control Center) and Brazil (Satellite Control Center). Its orbit is near polar sun-synchronous with an altitude of 778km, crossing Equator at 10:30am in descending direction, frozen perigee at 90 degrees, and providing global coverage of the world every 26 days. The attitude dynamical model is described by nonlinear equations involving the Euler angles. The attitude sensors available are two DSS (Digital Sun Sensor), two IRES (Infra-Red Earth Sensor), and one triad of mechanical gyros. The two IRES give direct measurements of roll and pitch angles with a certain level of error. The two DSS are nonlinear functions of roll, pitch, and yaw attitude angles. The gyros furnish the angular measurements in the body frame reference system. Gyros are very important sensors, as they provide direct incremental angles or angular velocities. They can sense instantaneous variations of nominal velocities. An important feature is that it allows the replacement of complex models (different torques acting on the space environment) by using their measurements to turn the dynamical equations into simple kinematic equations. However gyros present several sources of error of which the drift is the most troublesome. Such drifts yield along time an accumulation of errors which must be accounted for in the attitude determination process. Herein one proposes to estimate the attitude and the drift of the gyros using the Least Squares Method. Results show that one can reach accuracies in attitude determination within the prescribed requirements, besides providing estimates of the gyro drifts which can be further used to enhance the gyro error model. |
