Active satellites projected from current TLE elements pulled from CelesTrak and propagated with satellite.js.
Categories
Surveillance / IMINT, SIGINT, GNSS (GPS, Galileo, BeiDou), Starlink and OneWeb mega-constellations, weather, the ISS and crewed vehicles.
Methodology
SGP4 propagation from TLE → ECI → ECEF → globe. Re-anchored every 6 hours. Altitude is plotted to scale; footprints are derived from beam geometry where the operator publishes it.
