The NanoSat Air Bearing developed by Berlin Space Technologies is a test platform dedicated to test the ADCS of nano satellites. It was designed to have a very low moment of inertia to allow measurements with errors of less than 10% even for 1U Cubesats. The NanoSat Air Bearing is suitable for 1-3U Cubesats. Its modular design allows integration of Helmholtz coils and a sun simulator.
The first NanoSat Air Bearing has been built and successfully used for the implementation of the attitude control system (iADCS-100) of the Aalto-1 satellite.
