Attitude Control System
Attitude Control System (ACS) is a subsystem of a spacecraft that is responsible for maintaining the spacecraft's orientation and stability in space. ACS uses various sensors, such as gyroscopes, accelerometers, and star trackers, to determine the spacecraft's attitude and correct any deviations from the desired orientation. ACS also uses thrusters, reaction wheels, and magnetic torquers to apply corrective forces and torques to the spacecraft. The ACS is critical for the success of a mission, as it ensures that the spacecraft's instruments and antennas are pointed in the right direction and that the solar panels are facing the sun for power generation. ACS also plays a crucial role in the safe operation of the spacecraft, as it can be used to avoid collisions with other objects in space.
