More Information
Summary:The invention concerns a device (30) for determining an attitude of a satellite (10), the satellite comprising an attitude control system comprising a gyroscopic actuator (20) comprising a flywheel (21) mounted such that it can rotate about an axis of rotation and carried by a universal joint (22) articulated to rotate about an axis of rotation. This device (30) comprises: an attitude sensor (31) capable of measuring the attitude of the satellite; a position sensor (32) capable of measuring the angular position of the universal joint (22) about its axis of rotation; a speed sensor (33) capable of measuring the speed of rotation of the flywheel (21); and calculating means (34) configured to determine the attitude of the satellite (10) using the measurement of the angular position of the universal joint (22), the measurement of the speed of rotation of the flywheel (21) and the attitude measurement of the satellite (10).
