The Attitude Determination and Control Subsystem (ADCS) is very essential for stabilizing the satellite in orbit and ensuring that it points in the direction it is supposed to point in. For a systematic understanding the functions and various components of ADCS, we have organized the contents in a systematic manner as shown below:
