OLFAR: Adaptive topology for satellite swarms

Low-frequency space observation is one of the developing directions in radio astronomy, as scientists try to reveal more of the universe. The Orbiting Low Frequency Array for Radio Astronomy project is aimed at developing a distributed radio telescope sensitive to ultra-long waves, by placing an array of antennas, far away from any terrestrial interference. It will consist of over 50 small satellites grouped in a swarm capable of collecting and processing astronomical data. The system will use its resources to the limit and will need an efficient communication topology in order to guarantee functionality. In this paper we present a clustering scheme that reduces data distribution efforts at the cost of decreasing imaging redundancy
