This system utilizes a real-time tip-tilt control loop on an NVIDIA Jetson platform to stabilize optical beams for satellite-to-ground quantum key distribution. By pairing a voice-coil fast steering mirror with centroid-based InGaAs camera feedback, the system achieves precise coupling despite atmospheric turbulence. Laboratory validation against synthetic, turbulence-matched disturbances confirms effective performance for high-bandwidth free-space quantum links.
