ADCS-40m Integrated Attitude Determination and Control System

ADCS-40m is an integrated ADCS with four variable-speed, single-gimbal Control Moment Gyroscopes (CMG) which is suitable for 12U and 16U CubeSats.

It delivers the same performances compared to ADCSs designed for similar sizes of satellites but offers lighter weight, smaller volume, and less power consumption. Moreover, the user's onboard computer (OBC) only has to input attitude quaternion as the reference command or set the system to autonomous mode.

Attitude determination and control algorithms embedded in the ADCS computer take care of all the commanding tasks to the ADCS components. This enables the user's OBC to focus on the mission operation instead of calculating the complex system dynamics of the spacecraft.

Also, autonomous modes can allow the satellite to track terrestrial objects or the sun simply by setting the states of the ADCS.
