The CubeSense module is an integrated sun and nadir sensor for attitude sensing. It makes use of two CMOS cameras – one dedicated to sun sensing and another for horizon detection. The sun sensor has a neutral density filter included in the optics. Both cameras have wide FOV optics. The primary outputs of the sensor are two angles that can be used to calculate the sun and nadir vectors relative to the CubeSense camera boresights.
