Satellites and subsystems > Attitude > Attitude actuators > Reaction wheels > RW20 | 20 mNms
Key highlights
The RW 20 is designed for detumbling, attitude control, and torque or angular rate control of nanosatellites with a mean torque of 2 mNm.
The system is fully characterized and qualified according to the European Cooperation for Space Standardization (ECSS) and has an 8 years lifetime duration.
- Seamless Integration: Plug-andplay architecture with fully embedded electronics.
- Space-Proven Reliability: Radiation-tolerant design paired with high-grade stainless-steel bearing technology.
- Optimized Design: Compact footprint for easy accommodation within crowded satellite internal layouts.
Applications
Earth observation, science missions, and telecom constellations.
Missions requiring compact, radiation-tolerant components
Key features
- Operational lifetime: Minimum 8 years in LEO (model-dependent)
- Max Speed: Up to 6 000 RPM
Flight heritage
Few in orbit (since may 2025).
Flight-tested: Qualified through extensive testing and in-orbit performance validation.
