Free. No account, no subscription, no ads. The free version tracks everything, not just the ISS. Ten thousand satellites are flying over your head right now. SatRadar shows you every one of them, where they actually are, doing what they actually do — drawn from the same orbital telemetry that mission controllers and ground stations use every day. Open the app and the sky is already alive. Accurate to the second: real orbital telemetry, the same TLE data NORAD publishes, checked against ground truth. This is the sky we built. The Space Age started as one beep from Sputnik in 1957 and turned into a near-continuous procession of launches that has put more than ten thousand active spacecraft above us — Starlink and OneWeb meshing the planet in broadband, the GPS / GLONASS / Galileo / BeiDou networks holding civilisation's clocks, weather sentinels watching whole oceans, the ISS and Tiangong with humans aboard. SatRadar lets you watch all of it move, in real time, at the scale it actually is. Free to use, with no account required: • The International Space Station and Tiangong, traced across the sky in real time • The complete global navigation networks: GPS, GLONASS, Galileo, and BeiDou • Weather sentinels watching from geostationary perches: GOES, NOAA, METEOSAT • Full orbital trails on the GNSS fleet, so you can see the mathematical poetry of a 12-hour orbit at a glance • Tap any satellite to see what it is, where it is going, and how high above you it sits right now A one-time Starlink unlock opens the full mesh — nearly ten thousand satellites appearing as a living lattice around the planet, every laser cross-link drawn between its real endpoints, every hop between birds animated in actual sequence. The same unlock brings the rest of low Earth orbit with it: OneWeb threads its broadband shell, Iridium NEXT lights up the polar planes, the commercial Earth-observation fleets from Planet, Spire, and IceEye start watching, and the communications constellations of Astranis, O3B, Orbcomm, and Globalstar show up in their actual orbital planes. It is the most complete picture of human activity in low Earth orbit you can hold in your hand. A second one-time unlock — Time Travel — turns the whole thing into a time machine. Go back to October 1957 and the sky empties to a single object: Sputnik 1, circling a planet that had never seen an artificial moon. Move forward and watch it fill in: GPS through the 80s and 90s, the ISS assembling itself from 1998, the low-Earth shell suddenly igniting as Starlink starts launching in 2019 — sixty birds at a time, piling up into the mesh that wraps the planet today. Every satellite appears on its real birthday and moves on its real orbit. Six decades of the Space Age, laid out in front of you. The smoothness is the point. Real-time orbital propagation at constellation scale is genuinely difficult — most viewers buckle under a few hundred objects. SatRadar runs a custom GPU-side SGP4 propagator that holds every satellite at sixty frames a second, on a phone, while you rotate the globe and zoom from city to constellation in one continuous gesture. A few more touches that took a while: • Day and night terminator drawn live across the Earth, with atmospheric scattering at the edge • A stylised, richly textured globe — 8K Earth with live map tiles at close zoom • A star-accurate sky: the Sun, Moon, and the brightest stars in their true positions, every frame • Follow any satellite: lock the camera to it and ride along as it crosses the planet Both unlocks are optional one-time purchases — the app is complete without them. Never a subscription. Family Sharing supported, restored automatically across your iPhone, iPad, and Apple TV. Look up. Then look here. We are absolutely a spacefaring species — finally, suddenly, ridiculously — and you are walking around under the proof of it.
