Live Satellite Tracker
Real-time position, ground track, and pass prediction using SGP4 orbital propagation. Loads live TLE data from CelesTrak where possible; falls back to manual paste if your browser blocks the cross-origin request.
Propagation via SGP4 (satellite.js, embedded locally — MIT licensed). TLE data source:
CelesTrak. The satellite fleet list is shared with the GEO Eclipse Calculator tool, and the ground station presets use the same station list intended for the upcoming Link Budget Calculator ground-station table. Accuracy degrades the further the current time is from the TLE epoch shown above each satellite's live panel — for GEO satellites this is typically fine for days to a couple of weeks; for LEO satellites, fetch a fresh TLE if it's more than 1–2 days old.
