About
The Honeywell HC9 Reaction Wheel Assembly (RWA) features plug-and-play attitude control system insertion with minimized vehicle integration time. Roughly nine inches in diameter, it is designed specifically for small satellites, offering higher momentum storage than the HC7 while maintaining high performance with reduced cost and lifespan versus larger heritage wheels. Uses integrated electronics with an RS422 digital interface.
