AAC hyperion's next generation, high-performance reaction wheels are ideal for highly agile small satellite missions requiring accurate pointing
The RW222 series reaction wheels are low mass, low power reaction control wheels, which allow CubeSats and other pico- or nano-satellites to control their attitude. Based on almost a decade of design and flight heritage from the RW210, which demonstrated impressive space-based capabilities stretching across a range of applications, the RW222 design not only utilises our trusted inherent architecture but incorporates new and improved design upgrades enabling superior performance, improved pointing and exceptional torque whilst maintaining our compact form factor. The RW222 is the perfect addition to your system if you require a highly agile satellite with precision pointing.
The RW222 series of reaction wheels feature an internal fire-and-forget controller, which frees up the host processor’s workload. Our reaction wheels feature an internal fire-and-forget controller, which frees up the host processor’s workload.
The standard configuration features up to 2 mN.m torque, and an I²C interface.
Different interfaces are available on request.
The RW222 is available with either 3.0 or 6.0 mN.m.s of momentum storage in both directions of rotation.
Miniaturised
Within this range of angular momentum storage (3 to 6 mNms), the RW222 series reaction wheels have one of the lowest mass and dimensions in the market.
Integration
Specifically designed for 1 to 3U CubeSat platforms, these low mass reaction wheels are also used in the iADCS series of attitude determination and control systems.
Design
The RW222 reaction wheels have been subject to continued improvement ever since their first flight in 2017. This agile design approach ensures that changing user needs with regards to micro-vibrations, bearings, or shock absorption will be met.
