This satellite Attitude Determination and Control System (ADCS) is designed for CubeSats ranging from 1.5U, 2U, 3U, to 6U. A full set of attitude determination / actuator hardware and firmware is embedded. This subsystem combines 6 Fine Sun Sensors (FSS100 from Tensor Tech), 1 reaction sphere (RS100 from Tensor Tech), and a tactical grade gyroscope, to provide a pointing accuracy up to 0.2 deg (3-sigma) when the sun is capturable and 1 deg (3-sigma) when it is not. A GPS module can increase the attitude determination precision.
