Swarms of CubeSats for kW-scale Space-Based Solar Power (16U4SBSP) Executive Summary Report (ESR) Study Open Space Innovation Platform (OSIP) campaign, “Innovative Mission Concepts Enabled by Swarms of CubeSats” Affiliation(s): Sirin Orbital Systems AG (Prime, CH), Delft University of Technology (Sub 1, NL), University of Strathclyde (Sub 2, UK) Activity summary: The “16U4SBSP” mission concept is a fundamental technology demonstration step for the realization of kW-/MW-/GW-scale Space-Based Solar Power (SBSP) based on flight formation, a distributed or aggregated swarm of small satellites contrary to conventional concepts of monolithic giant SBSP satellites. In this mission, a swarm of 16U CubeSats collaboratively supply wireless power via Radio- Frequency waves to end-users in different locations on the ground, for instance to provide backup power for emergency situations, and also for space-to-space commercial use-cases.
