The IADCS-100 from Berlin Space Technologies is a ADCS System that is designed to provide high accuracy and precision attitude control for CubeSats. This ADCS system has attitude pointing of less than 1 degree and supports the 12C +RS-422, and RS485 interface. The iADCS-100 system includes a star tracker, reaction wheels, gyro module, magnetometer, accelerometer and Magnetorquer. It has a power consumption of 1.15-2.7 W. It has a mass of 400 g and measures 105 x 91 x 32 mm3 in dimension. The ADCS system incorporates the ADCS algorithms from the LEOS platform and allows full ADCS functionality including nadir pointing as well as autonomous target acquisition and tracking.
