Most people have looked at a flat satellite map before — a Mercator projection covered in fast-moving dots. It shows you where satellites are, but it does not show you how they orbit. A flat map cannot capture altitude, inclination, or the true three-dimensional geometry of a constellation. 3D satellite tracking solves all of that.
SatFleetLive now includes a full interactive 3D globe, powered by CesiumJS and real NORAD orbital data, that lets you explore over 14,000 satellites in accurate real-time orbits — directly in your browser, with no download or account needed. This guide explains how it works, what to look for, and how to get the most out of it.
What Is 3D Satellite Tracking?
Traditional satellite trackers display satellites on a 2D world map. While useful, this representation has a critical flaw: it projects a sphere onto a flat surface, which distorts distances, sizes, and especially orbital paths. A polar orbit shown on a 2D map looks like a diagonal zigzag — when in reality it is a smooth circle around Earth.
A 3D satellite tracker renders Earth as a realistic globe and positions each satellite at its true altitude above the surface. You can orbit the view, zoom in on specific regions, and directly observe how different orbital families — LEO, MEO, and GEO — relate to each other in three-dimensional space.
The 3D mode uses CesiumJS — an open-source WebGL globe engine — combined with the SGP4 propagation model and live TLE data from CelesTrak/NORAD. Every satellite position is computed in real time inside your browser. No server-side rendering, no lag. The globe updates satellite positions every 2 seconds.
2D vs 3D: Why the Globe Changes Everything
The difference between a flat tracker and a 3D globe is not just cosmetic. It fundamentally changes what you can understand about satellite behaviour.

How to Use SatFleetLive's 3D Mode
Switching to 3D takes one click. No registration, no download, no plugin — the entire globe runs in your browser using WebGL.
- Open SatFleetLive Go to satfleetlive.com. The tracker loads by default in 3D mode. If you are in 2D, you will see a "3D (Beta)" button in the top bar — click it to switch.
- Navigate the globe Left-click and drag to rotate the Earth. Scroll to zoom in and out. Right-click and drag to tilt the camera angle. On mobile, use two fingers to pinch-zoom and one finger to rotate.
- Apply filters Click ▼ Filters in the top bar to select which satellite categories to display. Selecting just "Space Station" will isolate the ISS for a clean view of its orbital path. Selecting "GPS" shows you the entire MEO navigation shell.
- Click any satellite Clicking a point on the globe opens the satellite info panel showing its name, altitude, velocity, latitude, and longitude — all updated live. A dashed orbital path arc appears showing its trajectory for the next two hours.
- Search by name or NORAD ID Type any satellite name (e.g. "ISS", "Hubble", "GOES-16") or its 5-digit NORAD ID in the search bar. The camera flies to that satellite and opens its info panel automatically.
- Enable "Only Visible" Toggle the Only Visible button to filter to satellites currently above your horizon and in sunlight — the ones you could actually spot with the naked eye tonight. Your location is used locally and never sent to any server.
3D mode requires a browser with WebGL support — all modern versions of Chrome, Firefox, Edge, and Safari on desktop and mobile support this. On older or lower-powered devices, performance may be reduced when displaying all 14,000+ satellites simultaneously. Use the filters to reduce the rendered count for smoother performance.
What You Can See in 3D
International Space Station
Watch the ISS race across the globe at 27,600 km/h. In 3D, its 400 km altitude is visible above the surface and its 51.6° inclination is immediately apparent — it never passes over the poles.
Starlink Constellation Shell
Enable "Starlink / Internet" to see the full Starlink mega-constellation arranged in precise orbital shells at ~550 km altitude. The geometric symmetry of the constellation is only apparent in 3D.
GPS Navigation Shell
The 31 GPS satellites orbit at 20,200 km — far above the dense LEO swarm. In 3D you can clearly see why their higher altitude allows just 24–31 satellites to provide global coverage.
Geostationary Weather Satellites
GEO satellites like GOES-16 and EUMETSAT's Meteosat appear nearly motionless in an arc above the equator at 35,786 km — visually distinct from all the racing LEO traffic below.
Polar Orbiting Satellites
Sun-synchronous weather and Earth observation satellites — like MetOp and Sentinel — orbit in near-vertical paths. In 3D, their coverage of the entire globe including the poles is immediately obvious.
Your Location on the Globe
Your position appears as a red marker on the 3D globe. Enabling "Only Visible" highlights every satellite currently above your horizon — showing you exactly which part of the sky to look at.
Understanding Orbits in 3D: LEO, MEO and GEO
One of the most educational things you can do with a 3D satellite tracker is observe the three main orbital families simultaneously. In 2D they overlap into visual noise. In 3D the distinction is immediate and intuitive.
Low Earth Orbit (LEO) — the fast inner swarm
LEO satellites — Starlink, the ISS, weather satellites — orbit between 160 and 2,000 km above Earth's surface. In 3D, they appear as a dense cloud just above the globe, moving rapidly. A single Starlink satellite crosses your field of view in seconds when zoomed in. The geometric structure of constellations like Starlink — precise orbital planes evenly distributed around the globe — is only fully visible in 3D.
Medium Earth Orbit (MEO) — the navigation shell
Enable the GPS filter and zoom out. You will see 31 dots forming a sparse but regular pattern at roughly 20,200 km — three times the diameter of Earth away from the surface. They move slowly compared to LEO satellites. This is why GPS satellites are easy to track with a fixed dish antenna: they are far enough away to move slowly across the sky.
Geostationary Orbit (GEO) — the stationary arc
At 35,786 km above the equator, GEO satellites barely move. Enable the Communications or Weather filter and zoom out to see the full picture: a ring of dots hovering in a perfect arc above the equatorial plane. From their vantage point, each one covers about 42% of Earth's surface continuously — the 3D view makes this immediately obvious in a way no flat map can replicate.
Open SatFleetLive in 3D, enable all filters, and slowly zoom out until you can see all three orbital shells at once. The inner LEO cloud, the sparse MEO ring, and the stationary GEO arc paint a complete picture of humanity's presence in space — 14,000+ objects, all orbiting in real time.
Tips for Getting the Most from 3D Mode
Isolate one category
With all filters enabled, 14,000+ satellites create visual noise. Deselect everything except "Space Station" or "GPS" to explore one orbital family cleanly.
Zoom to orbit altitude
After clicking a satellite and seeing its orbit path, zoom the camera out to match its altitude. You will see the orbit as a complete circle — often tilted at a striking angle.
Compare LEO and GEO together
Enable both Starlink and Communications at the same time. Zoom out until both orbital shells are visible. The contrast in altitude, speed, and density is dramatic and educational.
Search for famous satellites
Try searching "Hubble", "JWST", "GOES-16", "LANDSAT", or "NOAA-20". Each occupies a distinct orbit you can explore in 3D after the camera flies to it.
Combine with Next Passes
Find a satellite in 3D, note its NORAD ID, then switch to Next Passes to find exactly when it will cross your sky — then step outside and watch it live.
Use filters for performance
On mobile or older hardware, rendering all 14,000 satellites can be demanding. Deselect Starlink and Other to reduce the count to a few hundred for a much smoother experience.
