satellitemap.space: real-time map of Starlink, OneWeb and 30,000 satellites

What it is

satellitemap.space is an independent tracking site created by a developer known as Justin and online since 2019. It renders the public satellite catalogue on an interactive globe in the browser (WebGL) and specialises in the internet constellations: Starlink first, with OneWeb and the navigation systems alongside. The header counts more than 30,000 tracked satellites. Positions are propagated from public element sets (the menu links to Space-Track status; the same data is available from CelesTrak), so what you see is the catalogue's view, refreshed continuously.

What you can do with it

• Watch a constellation live: filter to Starlink and see the shells, the trains of freshly launched satellites raising their orbits, and the gaps; filter to OneWeb and see its twelve polar planes at 1,200 km.
• Constellation data pages: growth over time, launches, decays and re-entries, orbits, ground stations and events, which give a quick answer to "how many Starlink satellites are up today" without processing data yourself.
• Tools: a re-entries monitor, a transit finder, TLE analysis, a photo simulator, a close-approaches detector, SatNOGS radio integration, a ride-share identifier, watchlists and a "LEO box score" that compares constellations side by side.
• Historical views to replay how the constellation was built.

Who it is for

Resellers who need a visual answer for a customer ("why is service better here since last spring"), installers explaining that a dish points north in the northern hemisphere because of where the inclined shells fly, analysts checking claims about launch cadence, and anyone curious. It is quicker than a research tool and more informative than a vendor map. For provider choice it is background only: the map shows satellites, not capacity, licences or prices, which is what our Starlink and OneWeb listings are for.

How to use it

1. Open the globe and select the Starlink layer; zoom to your region and hover a satellite for its designation, altitude and velocity.
2. Open the constellation data section for the growth and decay charts before quoting a figure; screenshot with the date.
3. Use the ground-station layer to see how far your site is from the nearest gateway, one of the factors behind regional latency differences.
4. Add satellites to a watchlist if you follow a specific launch.

Limits

It is one person's project, supported by donations, with no API guarantees; accuracy is that of public element sets (kilometres, not metres). It does not show beams, cell availability or performance. Use Starlink's availability map for what can be ordered and LeoLabs for professional conjunction data.
