Watchlists that stick
Group the objects you care about into named lists. They sync to your account and follow you across devices.
Your own objects
Paste a TLE or ephemeris and propagate your satellites live, right alongside the public catalog.
Alerts
Get notified when a watched object maneuvers, reenters, or has a close approach.
API access

FAQ
Straight answers.
- Is Vantafort free?
- Yes. Browsing the full catalog, conjunction and reentry events, and maneuver detections is free with no account. A free account adds watchlists, alerts, and lets you track your own objects.
- Do I need to install anything?
- No. Vantafort runs entirely in your browser: open the platform and the full catalog is live in seconds. There is nothing to download and no license to buy.
- What do I need to run it?
- Just a browser. Vantafort runs on all modern browsers, using WebGPU to propagate the entire catalog on your GPU. Nothing to install, no minimum spec.
- Where does the orbital data come from?
- From the US Space Force's public satellite catalog, via Space-Track. Elements are refreshed continuously, and every position you see is propagated live from the most recent set, not replayed from stored tracks.
- How accurate is the tracking?
- Propagation runs the full SGP4/SDP4 specification, including deep-space corrections, validated to sub-55-meter mean error against the standard Vallado reference test suite. Maneuver detection is validated against ILRS laser-ranging ground truth at 92.2% precision. Both methods are published, with full error analysis, in our research.
- Can I track my own satellite?
- Yes. With a free account you can paste a TLE or ephemeris and your object is propagated live alongside the public catalog in every view.
