Attitude control devices, satellites, attitude control methods, and programs

摘要

The attitude control device (20) includes an ideal thrust direction calculation unit (22), an ideal attitude calculation unit (24), a target attitude calculation unit (26), and a torque calculation unit (28). The ideal thrust direction calculation unit (22) calculates the ideal thrust direction of the thruster. The target attitude calculation unit (26) calculates the target attitude, which is the attitude of the satellite that minimizes the deviation from the ideal attitude while the panel surface faces the sun within the range of the drive constraint of the attitude control actuator (14). To do. The torque calculation unit (28) calculates the torque for rotating the satellite from the actual attitude to the target attitude, and sends a torque command to the attitude control actuator (14).
