ESTEC

CubeSpec is a 12U CubeSat designed for high spectral resolution spectroscopy of visible light, marking ESA's first astronomy CubeSat. It utilizes a High-Precision Pointing Platform (HPPP) developed by KU Leuven to enhance its attitude control system. Testing occurred at ESTEC's ORBIT facility, simulating space conditions for accurate tracking of target stars during its in-orbit technology demonstration.
