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.
