Skyport is a free, browser-based 3D satellite tracker that shows the live position of every broadcasting satellite orbiting Earth. Built with Three.js and real orbital mechanics (SGP4 propagation from CelesTrak TLE data).
Skyport is a free, real-time 3D satellite tracker that runs entirely in your browser. It shows live positions of ISS, Hubble, JWST, Starlink, Tiangong, GOES weather satellites, and more using real TLE data from CelesTrak.
Skyport uses SGP4 orbital propagation with Two-Line Element (TLE) data updated hourly from CelesTrak — the same math used by NASA and NORAD.
