Key highlights
CubeSpace (CS) offers a wide range of robust reaction wheels perfect for CubeSats and SmallSats. Our reaction wheel range is designed for precision performance, reliability, ease of use, and manufacturability. Featuring a modular, space-proven design with in-house designed motors, high-load space-rated bearings, and advanced lubrication, our wheels can be easily optimized to meet mission-specific requirements. This is achieved by adjusting the motor or using alternative bearings or lubrication and does not impact manufacturability due to this design’s built-in modularity.
Additionally, our wheels are meticulously balanced using our state-of-the-art automated laser balancing machine, ensuring outstanding vibration tolerance through stringent micro-vibration testing. This high tolerance, with the option for additional damping, makes our reaction wheels an ideal choice for missions requiring high precision and stability. With a distributed supply chain and automated production processes, the CS reaction wheel range offers robust, customizable, high-precision wheels that can be rapidly manufactured at high volumes and competitive pricing.

Testing & qualification
Our satellite subsystems’ manufacturing, assembly, integration, and testing adhere to international space standards. We design these subsystems with carefully selected components and subject them to rigorous testing under ESA’s ECSS and NASA’s GEVS standards, including radiation, vibration, shock, and thermal vacuum tests. Utilising in-house test equipment enables us to validate product performance efficiently and cost-effectively, ensuring reliable and high-quality products and services for our ambitious partners.
