Satellite Trackers Real-Time Orbital Tracking

Track space stations, mega-constellations, navigation satellites, space telescopes, orbital debris and atmospheric re-entries in real time. Every tracker shows live position, altitude, speed and orbital path — updated every second using SGP4 propagation.

Space Stations

Crewed orbital laboratories in low Earth orbit. Track each station's live position, altitude, speed, crew manifest and upcoming visible passes from your location.

Frequently Asked Questions

How do satellite trackers work?
Our trackers use Two-Line Element sets (TLEs) published by Space-Track and CelesTrak, combined with the SGP4 propagation algorithm, to calculate each satellite's position in real time. The result is accurate to within a few kilometres for most objects and updates every second in your browser. Learn more about TLEs in our What Is a TLE? guide.
How many satellites can I track?
Orbital Radar's satellite directory contains over 14,000 active satellites. Every catalogued object has its own profile page with live tracking. The dedicated trackers on this page highlight the most popular constellations and objects, but you can track any satellite in our database.
Can I see satellites from my location?
Yes — use our Satellite Pass Predictions tool to see exactly when any satellite will be visible from your location, with sky charts, countdown timers and brightness estimates. Most satellites are visible within 1–2 hours after sunset or before sunrise. Radio passes work any time — day, night, or through clouds.
What data sources do the trackers use?
Orbital elements come from the US Space Force's 18th Space Defense Squadron via Space-Track.org and CelesTrak. Supplementary data — mission details, operator info, launch dates — is cross-referenced from public catalogues and our own editorial research. See our data sources page for full details.
How accurate is real-time satellite tracking?
SGP4 propagation from fresh TLEs is typically accurate to within 1–5 km for well-tracked objects in LEO. Accuracy degrades as TLEs age or for objects with high drag variability. Our How Satellites Are Tracked guide explains the full tracking pipeline from radar observation to your screen.
What is the difference between LEO, MEO and GEO satellites?
LEO (Low Earth Orbit) is roughly 160–2,000 km altitude — home to the ISS, Starlink and most Earth observation satellites. MEO (Medium Earth Orbit) spans 2,000–35,786 km and hosts navigation constellations like GPS and Galileo. GEO (Geostationary Orbit) is at exactly 35,786 km where satellites match Earth's rotation and appear stationary. See our Types of Orbits guide for more.
