The NanoSat Air Bearing developed by Berlin Space Technologies is a test platform dedicated to test the ADCS of nano satellites. It is designed to have a very low moment of inertia which allows 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 iADCS attitude control system of the Aalto-1 satellite.
