TLE / SGP4
Live satellite tracker
Catalog objects from public orbital elements, shown on the 3D globe. Specialist pass tables still win for a single site; the advantage here is satellites next to flights, news, and hazards.
Orbits versus radar
TLE + SGP4 is a prediction from published elements. It is not a dish lock. Conjunction and debris views are extra layers with their own honesty labels.
How to use this view
- Launch in 3D with Satellites on.
- Click a bird for name and catalog id.
- Use the ISS or Starlink pages if that is the actual query.
- Turn Earth clutter off so the orbit is visible.
Data source, update rate, and limits
Public TLE catalogs (CelesTrak-class). Propagation is computed in the client. Catalog refresh is minutes, not milliseconds.
Maneuvers lag the TLE. Classified objects are absent. Do not aim a laser or a legal claim at a propagated dot.
Questions
Is this real-time radar?
No. It is orbital mechanics on public elements.
Can I see satellites over me tonight?
Zoom to your city, enable Satellites, and use ISS pass tools if you care about one bright object.
Where is Starlink?
The Starlink tracker enables that constellation mode. Dense draws are expensive; Premium may apply.
Do you track space debris?
Conjunction and debris-related layers exist as public catalogs, not as a collision-avoidance service.
Why use this instead of a specialist?
Because the same desk can show a launch, a storm, and an orbit without three subscriptions.
