Key highlights
VAC02 is a fully integrated, versatile ADCS solution designed for CubeSats with 1U to 3U form factor. It is equipped with three reaction wheels, three magnetorquers as actuators and up to six fine sun sensors, two magnetometers, and three gyroscopes as sensors. This compact solution with Cortex-M7 computer provides exceptional pointing awareness and performance for smaller CubeSats.
