Attitude Control Systems
Attitude Control Systems (ACS) are a set of subsystems that enable a spacecraft to maintain its orientation and pointing with respect to a reference frame. ACS is responsible for controlling the spacecraft's attitude, which is the orientation of the spacecraft with respect to an inertial frame or a celestial object. The subsystems that make up ACS include sensors, actuators, and control algorithms. Sensors provide information about the spacecraft's attitude, while actuators apply torques to the spacecraft to adjust its attitude. Control algorithms process sensor data and generate commands for the actuators. ACS is critical for the success of a mission, as it enables the spacecraft to perform its intended tasks, such as pointing a scientific instrument at a target or maintaining communication with Earth.
