Questions
Is Orbital Traffic free?
Completely free. No ads, no subscriptions, no account required.
Does it work without an internet connection?
Yes — after the first load it works offline, and the catalog refreshes automatically the next time you're online.
Is my location ever sent anywhere?
No. What's Overhead uses your location entirely on your device to work out what's above you — it's never transmitted or stored, by us or anyone else.
What platforms does it run on?
iOS is available now on the App Store. It also installs as a full app on Android and desktop straight from your browser, no app store required.
Where does the data come from?
Real orbital data from CelesTrak, NASA/JPL, and Launch Library 2 — refreshed continuously, not simulated.
Is it to scale?
Orbital positions are exactly to scale — every altitude is drawn true, so the space station really does fly that close to the surface and the geostationary ring really is that far out. Object sizes are not, and cannot be: at a typical zoom one pixel covers tens of kilometres, so a satellite drawn true to size would be smaller than a single pixel. The dots are map markers, like a city on a road atlas.
