The RWA05 from Berlin Space Technologies is a Reaction Wheel that is designed for small satellites with a lifetime of 5 years in LEO orbit. It has a torque of 14.2-16 mNm and an angular momentum of 0.5 Nms. This reaction wheel has a mass of 1.7 Kg and a velocity of 0.5 Nms. It requires a DC supply of 5-32 V and has a power consumption of 0.5 W. This reaction wheel supports RS-422 and UART interfaces. It consists of an integrated fiber optical gyroscope that allows for precise control loops such as precise speed, angular rate, and angle control loops of satellites. This reaction wheel measures 105.0 x 106.6 x 109.5 mm.
