About
The RWA05 is a reaction wheel developed by Berlin Space Technologies (BST) for use in small satellites. It is designed to provide precise attitude control for spacecraft. The unit can be optionally delivered with an integrated fibre optical gyro, which further enhances its precision capabilities. BST has a significant track record with this product, having delivered over 100 units to various customers. The RWA05 has demonstrated its reliability and performance in orbit, with space heritage dating back to 2015. Its specifications include an angular momentum storage of 5 arcsec, a net torque of 14mNm, and a typical operating speed of 5000rpm. Speed control accuracy is maintained at +/- 2rpm. The device communicates via an RS422 data interface. It has a compact size of 105x107x110mm and a design life of 5 years. The mass varies depending on the configuration: 1700g with the integrated gyro and 1500g without it.
