Attitude Control: Methods and Devices

This lecture covers different types of attitude control methods used in space missions, including gravity gradient, magnetic torquers, spinning spacecraft, momentum devices like reaction wheels, and thrusters. It explains how magnetic torquers work, their torque expression, and provides examples of their application, such as on the Hubble Space Telescope. The concept of spinning spacecraft and three-axis stabilized spacecraft controlled by reaction wheels, Control Momentum Gyros, or thrusters is also discussed.
