Look up. Someone's passing over.

Follow a satellite
Tap one to see when it flies over you.
Where to point
Live azimuth and elevation for the pass you pick, measured from your location. Point at the AOS mark before the pass starts, then follow the track until LOS.
Live pointing
Doppler shown is for receiving. Transmitting to a satellite needs an amateur radio licence or other authorisation where you are.
Upcoming passes, next 2 days
Pointing table
Computed with SGP4 from the latest public orbit data (CelesTrak). Elevation is geometric, with no correction for atmospheric refraction. Accuracy is typically a few kilometres with fresh data, usually close enough for handheld and Yagi antennas. Get fresh elements before pointing a narrow-beam dish. Not for navigation, safety-critical use, or operating spacecraft.
Every pass over you
Green rows are passes you can see with your own eyes: the satellite is in sunlight while your sky is dark. The rest fly over in daylight or in Earth's shadow.
Free Starlink Wi-Fi at 35,000 feet
More airlines now use Starlink, the same satellites on the globe, for fast in-flight Wi-Fi. Many give it away free. Check your airline before you fly.
Free to look. Pay for the tools that do more.

Six minutes that make you feel connected
Right now there are people living 420 km above you, and the satellites that carry our calls, maps and messages cross your sky every night. Most people never notice. OrbitWatch tells you exactly when to step outside, where to look, and what you're seeing, so you can catch it with someone you love.
Wave at the astronauts
The ISS is the third brightest thing in the night sky. Get a heads-up before it rises, then share the moment with family or friends in other cities who see it too.
Plan the perfect shot
Know the exact second the station crosses the Moon or Sun, where to stand, and which way to point. These shots go viral, and they take minutes of planning instead of luck.
Point your antenna
Exact AOS, closest approach and LOS for any satellite, live azimuth and elevation, Doppler for your downlink, and a pointing table you can download.
Make space real
Teachers, scout troops and astronomy clubs get a live board of tonight's passes and the story behind every satellite overhead.
