摘要

Recent trends in scientific low Earth orbit satellite missions involve small, low-cost satellites communicating with multiple low-cost ground stations. We propose a peer-to-peer multicast ground distribution scheme accompanied by a best-effort broadcasting mechanism with randomized retransmissions that is tailored for such satellite missions. Through our simulation tools, we assess the performance of the new, low-cost model; evaluate the benefits of decentralized ground distribution; and quantify the trade-off between data reliability and data return volume.
