Sattrack — Real-time 3D Satellite Tracker

Sattrack is an open web application that computes real-time satellite positions from TLE (Two-Line Element) data and visualizes them on a 3D globe. It can simultaneously track thousands of satellites — including STARLINK, the ISS, Earth observation satellites, and communication satellites — letting you explore their orbits and current positions in your browser.

What you can do

• Visualize the live positions of thousands of satellites on a 3D globe
• Select an individual satellite by NORAD ID or name and follow it with the camera, including its orbit line
• Filter by satellite group (STARLINK, SatNOGS, etc.)
• Automatic updates based on the latest TLE data from Celestrak (orbit propagation uses SGP4)
