Dual Optimization and Control of VLEO Relay Systems via Multiplexed/Classical Multimodel MPC

Space: Science & Technology
Very low Earth orbit (VLEO) satellites face marked challenges in downlinking large volumes of data due to short ground station contact windows. To address this, we propose a data relay multisatellite system (DRMSS).
