Abstract

We propose polarimetric calibration of nano-satellites by pointing them towards solar panel farms or mirrors at solar thermal power plants. We show through simulations that both can provide significant polarization sources. Around a solar tower, this is obtained by polarized skylight reflected from mirrors. Photovoltaic solar panels, on the other hand, yield a strong polarized signal by reflecting direct sunlight around the Brewster angle. The signal is affected by aerosols. The aerosol uncertainty affects calibration tasks. Based on these findings, we simulate spaceborne polarimetric camera calibration.
