About TrackStarlink
TrackStarlink is an independent project that visualizes the SpaceX Starlink constellation in real time using public orbital data from CelesTrak. We compute satellite positions in your browser/server with the SGP4 model — no affiliation with SpaceX or Starlink.
Data sources
Orbital elements (TLEs) are sourced from CelesTrak and refreshed regularly. Positions are propagated using satellite.js.
