Attitude Control System

Quick Info

ACS is an Attitude Control System for low earth orbit satellites. The design is based on the innovative developments of Prof. Udo Renner, “Institut für Luft- und Raumfahrt” of the Technical University Berlin, and integrated in the well known TUBSAT satellites.


With a space heritage of seven TUBSAT satellites in orbit, ACS is a very reliable System for long life operation. ACS consists on high performance, high dynamic 3-axis torque and momentum exchange actuators in connection with high precision fibre-optic gyros for the measurement of the angular movements. One additionaladvantage of this combination is that reaction wheel and gyro form a self contained control loop for the rate or the angle of the satellite so that the OBDH is off loaded from any control task.
