Nowadays, spacecrafts are employed for a wide variety of missions: Earth's observation and monitoring, deep universe investigation, communication and much more. For the success of these missions, it is essential that the satellite is correctly oriented during space flight and maintains this orientation with high pointing accuracy in spite of various perturbations. This objective is pursued by Attitude Determination and Control Systems (ADCS), which is responsible to determine the true attitude and to control the actuators to track desired orientation. In contemporary space missions, the design of ADCS is complicated by the fact that modern satellites are equipped with different large devices featuring low stiffness and moving parts, such as antennas and solar arrays.
