Attitude Control Systems (ACS) are essential for maintaining the orientation of spacecraft and satellites in space. These systems use various sensors and actuators to determine and adjust the position of the vehicle, ensuring it remains stable and pointed in the desired direction. Common sensors include gyroscopes and star trackers, while actuators may involve reaction wheels or thrusters. The primary goal of an ACS is to manage the spacecraft's attitude, which is crucial for tasks like communication, navigation, and scientific observations. By effectively controlling orientation, the system helps optimize the performance of instruments and ensures proper alignment with targets, such as Earth or other celestial bodies.
