Design of an ADCS test stand for nanosatellites

ADCS test stands are used for on-the-ground testing of satellite altitude determination and control systems. Their main purpose is to simulate time-vaying conditions similar to those found in outer space on a geocentric orbit. The paper presents the main component of the ADCS test stand – a Helmholtz cage used to simulate the orbital magnetic field. The design and integration of mechanical, electrical, electronic and software components that led to a highly uniform and precisely controlled magnetic field is described here. The validation process, including 3D scanning of the magnetic field, is presented. Remarks on the employed technology, limitations of the proposed solution, some design recommendations, and plans for future work are provided.
