The Airbus CMG 75-75 S is a compact and high-performance control momentum gyroscope (CMG) solution designed for large satellites. Some of its key features include rigid preload in the bearings to withstand launch loads, satellite integration, highly accurate pointing performances, precise balancing of the wheel and very low friction in the gimbal bearings for very low disturbances, as well as integrated dampers to filter residual disturbances. The product weighs 69 kgs and can operate for ten years in the low earth orbit (LEO).
