Space-Based Solar Power (SBSP) is an innovative solution for providing power to general users. The concept involves positioning one or several high-powered photovoltaic solar stations on a highly and if possible continuously sunlit orbits and transmitting the harvested energy via high frequency beam (from narrow RF up to visible domain) to the envisaged users. In the past, use cases primarily focused on ground stations, while nowadays the idea to directly supply spacecrafts on orbit is becoming more and more attractive. The present work, intended as the final product of the double master's degree program between Politecnico di Torino and ISAE-Supaero, result of the final internship at Thales Alenia Space, focuses on this last trend.
