Hardware-in-the-Loop (HIL) and Software-in-the-Loop (SIL) System for Cubesat ADCS Testing

This paper proposes a low-cost testbed for a CubeSat attitude control system using Helmholtz coils to mimic the geomagnetic field in Low Earth Orbit. The testbed consists of square coils arranged along three axes, allowing for precise magnetic field control along the X, Y, and Z axes. The system is managed by a Hardware-in-the-Loop (HIL) setup, which enhances the Attitude Determination and Control System (ADCS) capabilities through closed-loop operation. This configuration ensures that the magnetic field can be accurately simulated, providing a realistic environment for testing and improving ADCS performance. Implementing such a testbed is not only cost-effective but also offers a high level of precision, making it a necessary tool for developing and testing CubeSat attitude control systems.
