OpenSN: open-source emulator for large LEO satellite networks
OpenSN, from Beihang University, emulates LEO satellite networks with one container per node so that real routing software runs on every satellite and gateway. It scales across machines and builds mega-constellations 5 to 10 times faster than StarryNet. Published in IEEE TPDS, August 2025.
Mega-constellations in three minutes: O3b mPOWER, OneWeb and Starlink
A concise academic explainer (November 2023) of non-geostationary constellations, comparing SES's O3b mPOWER in medium Earth orbit with OneWeb and Starlink in low Earth orbit, made alongside a Frontiers paper on connecting space missions through NGSO constellations. Good for the orbit and orbital-plane basics.
Hypatia: LEO satellite network simulation framework (ETH Zurich)
Hypatia is the reference open-source framework for simulating LEO networks: it generates a constellation and its routing over time (satgenpy), runs packet-level ns-3 simulations (ns3-sat-sim) and renders Cesium visualisations. From the IMC 2020 paper; 518 GitHub stars, last update May 2024.
