Our RWA-15s have accumulated over 2.5 million hours in space. The RWA-15 has an outstanding design heritage based on hundreds of space-qualified units launched to date. At least 25 units are in orbit today, with the longest unit operating for more than 14 years. The RWA-15 has performed on various remote sensing programs with demanding high-performance requirements, IKONOS, LEO, QuickBird, SWIFT and QUICKSAT.

The RWA-15 is a high-torque reaction wheel assembly with integrated electronics. It provides reaction torque for pointing and attitude stabilization of satellites demanding high-reaction torque and low-induced vibration. The high-performance torque motor achieves exceptionally low-torque ripple performance over the full-speed range. Internal electronics provide motor commutation, torque control, voltage regulation, wheel telemetry and self-protection circuitry.
