OPTOS is a 3U Cubesat, designed by the Instituto Nacional de Tecnica Aerospacial of the Spanish Space Agency, Madrid. Carries APIS (Athermalized Panchromatic Image Sensor) to study the degradation of lenses in the space environment by imaging the same region repeatedly under the same light conditions, FIBOS (Fiber Bragg Gratings for Optical Sensing) to measure temperature by studying a laser beam travelling across the optical gratings, and the GMR (Giant Magneto-Resistance) system to study magnetic fluxes in the Earth's magnetic field.
