Live Satellite Globe
Watch thousands of satellites orbit Earth in real time on an interactive 3D globe. Every position on screen is computed live in your browser from current orbital data — nothing is pre-recorded or animated on a loop.
What you can do on the globe
Spin, zoom and explore
Drag to rotate the Earth, scroll to zoom from the whole planet down to a single orbital shell, and watch satellites sweep past against real country borders and the day–night terminator.
Click any satellite
Select a dot to see what it is, how high it is, how fast it is moving, and the ground track it is following. Notable objects get a plain-English briefing of what the satellite actually does.
Filter by constellation
Show only Starlink, only GPS, only the space stations — or any custom group you have built — so the globe shows the fleet you care about instead of everything at once.
Put yourself on the map
Share your location and the globe marks where you are standing, so you can see which satellites are crossing your part of the sky right now.
Satellite positions come from two-line element sets (TLEs) published by Space-Track and CelesTrak, refreshed every two hours and covering thousands of active payloads across low Earth orbit, medium Earth orbit and the geostationary belt. AstroSat propagates those elements with SGP4 — the same standard model used by professional operators — inside web workers in your browser, so the globe keeps running smoothly without waiting on a server for every frame. Satellites are drawn in an inertial reference frame while the Earth rotates beneath them at its true sidereal rate, which is why orbits trace the familiar sine-wave ground tracks over time rather than staying fixed above one spot.
Frequently asked questions
How often do the satellite positions update?
Continuously. Positions are recomputed in your browser many times a second, and the underlying orbital data is refreshed every two hours.
Where does the orbital data come from?
Two-line element sets published by Space-Track and CelesTrak — the same public source professional trackers use.
Can I see a satellite orbit path?
Yes. Select a satellite and its orbit track is drawn on the globe so you can see where it has come from and where it is heading.
Does the globe work on a phone?
Yes. The globe runs in any modern mobile browser with touch controls for rotate and zoom, with no app install required.
