The RWA-05 by Berlin Space Technologies is a reaction wheel assembly with integrated fibre optical Gyro (RWA) for small satellites. The integrated gyro allows precise control loops such as precise speed, angular rate and angle control loops as they have been pioneered on Berlin satellites since 1994.
