About
NewSpace Systems’ NRWA reaction wheels provide spacecraft attitude control through momentum exchange between the satellite body and a rotating flywheel. The product line offers four standard sizes (T065, T2, T6, T25) with customized flywheel configurations for mission-specific optimization. The flagship NRWA-T065 has accumulated over 3 million failure-free operational hours since first flight in 2014 with zero reported single-event upsets. More than 800 units have been sold with the line baselined on four constellation programs. Control modes include current, speed, and torque control via a simple digital spacecraft bus interface, with an optional integrated gyroscope available on the T065.
