Design of a Polarization Diversity System for Ground Stations of CubeSat Space Systems

In this letter, a new polarization diversity system for ground stations that operate CubeSat spacecraft is presented. This new system aims to minimize communications link losses caused by unpredictable variations of the radiation pattern of the antenna in spacecraft that spin freely. It is based on the combination of multiple signals orthogonally polarized. The ground station that controls the XaTcobeo spacecraft has implemented this system. The spacecraft has been launched recently and is still in Launch and Early Orbit Phase (LEOP).
