Summary
A high-performance alternative to a propulsion-based reaction control system, reaction wheels provide spacecraft with control torque by means of momentum exchange between the satellite body and the rotating wheel.
The increasing popularity of these wheels coupled with our commitment to high-quality, fit-for-purpose components has resulted in NSS offering these wheels in a range of standard sizes (NRWA-T065, NRWA-T2, NRWA-T6, and NRWA-T80) or can offer a customized flywheel for mission optimization.
Applications
- High-performance three-axis torque and momentum exchange actuators for agile small satellite missions
- Momentum bias
- Inertial rate control for accurate pointing of imagers
Key features
- Wheel torque and momentum capacity suited to client mission requirements
- Current, speed and Torque control
- Simple digital interface to the spacecraft bus
- Integration with an optional gyroscope for inertial rate control and inertial angle control modes is possible on T065
- Hermetically sealed (T065 & T2)
- Long demonstrated lifetimes
