Attitude Determination And Control
Attitude Determination and Control (ADC) is a subsystem of a spacecraft that is responsible for determining and maintaining the orientation of the spacecraft in space. ADC systems use sensors to measure the spacecraft's attitude and then use actuators to adjust the spacecraft's orientation as needed. The sensors used in ADC systems include sun sensors, star trackers, and inertial measurement units (IMUs). The actuators used in ADC systems include reaction wheels, thrusters, and magnetic torquers. ADC systems are critical for the success of a spacecraft mission, as they ensure that the spacecraft is pointed in the correct direction for communication, scientific observations, and other mission objectives.
