Reaction Wheels Control System SatBus 4RW0 for SmallSat MIssions from NanoAvionics - Orbital Transports SmallSat Catalog

Reaction Wheels Control System SatBus 4RW0

NanoAvionics has designed reaction/momentum wheels (RW) which can be ordered as separate components or integral 4 reaction wheels redundant 3-axis control system, enabling precision pointing of the small satellite.

Reaction wheels includes DC brushless motors assembled in sealed housing providing no particle emissions and preventing contamination of peripheral devices.
