The KU Leuven ADCS from CubeSat Pointing is an Autonomous Attitude Determination and Control System (ADCS) that is suitable for use in CubeSats. It consists of gyroscopes, photodiodes, magnetometers, a star tracker, a flexible extended Kalman Filter, reaction wheels, magnetorquers, and a fine PID controller. This ADCS system has a mass of 0.715 Kg. It has a pointing accuracy of 0.11-6.3 deg and detumbling of +60 deg/s. This ADCS system has an RW momentum capacity of 4 mNms and an RW torque of 0.5 mNm. It requires a DC supply of 3.3-5 V and has a power consumption of up to 1400 mW. The KU Leuven ADCS supports I2C and CAN data interfaces and has an SGP4 Orbit propagator with autonomous switching modes. It measures 90 x 96 x 50 mm and is used for autonomous Nadir, Zenith, Sun, and LLA pointing and autonomous desaturation of reaction wheels.
