About
The CRW is a cogless reaction wheel used as an attitude control actuator, providing less than 1 arcsecond pointing control thanks to its cogless design that achieves less than 0.1% torque ripple. It is available in a range of momentum capacities from 0.1 to 2000 Nms and consumes up to 10W peak power. The CRW supports tetrahedral SmallSat configurations as well as balloon-borne configurations, with 1U/2U versions weighing 100g per wheel, and is rated for use from terrestrial through LEO environments.
