Satellite Tracker: Sky Map AR

What's that moving light in the sky? Find out in seconds.

Satellite Tracker turns your phone into a live AR sky guide. Spot the International Space Station (ISS) overhead, watch a Starlink train pass, identify constellations, and explore over 12,000 satellites in real time — with stunning visuals and the same SGP4 orbital math NASA uses.

★ AR SKY VIEW
Point your phone at the sky. The app draws the ISS, Starlink, satellites, stars and constellations directly over your camera feed. Align the zenith arrow and tap to identify any moving light in seconds.

★ ISS TRACKER & PASS PREDICTIONS
Know when the International Space Station will rise over your location, how high it will arc, and how bright it will be. Set notifications for the next 2 or 6 hours so you never miss a visible pass.

★ STARLINK TRAINS
Track SpaceX Starlink launches and the famous "string of pearls" formations. Filter the sky to show only the constellation you want.

★ 3D INTERACTIVE GLOBE
Switch from the AR sky view to a stunning 3D Earth globe. Layer satellites by category — Starlink, OneWeb, GPS, Galileo, GLONASS, geostationary, debris swarms — and watch them orbit in real time.

★ CLASSIC SKY RADAR
Old-school polar radar scope showing every visible pass over your head with bearing, elevation, range and time-to-closest-approach. Perfect for satellite spotters with binoculars.

★ STARGAZING & CONSTELLATIONS
Identify stars and trace constellation lines over the real sky. Brightness-graded star catalog with names for the major bright stars in every constellation.

★ MASSIVE OBJECT DATABASE
12,000+ tracked objects from the official NORAD / Celestrak feed:
• Active weather and Earth-observation satellites
• ISS and crewed spacecraft
• GPS, Galileo, GLONASS, BeiDou navigation constellations
• Geostationary communications satellites
• Famous debris fields (Iridium-Cosmos collision, Fengyun-1C ASAT)
• Search by name or NORAD catalog number
• Color-coded by orbit class — LEO, MEO, GEO, HEO

★ LIVE TELEMETRY
Tap any satellite to see live altitude, velocity, range and Doppler shift, plus next-pass times for your exact location.

★ MADE FOR DARK SKIES
• Light-pollution presets (Urban / Suburban / Rural / Dark Sky)
• Calibration Report — visibility predictions adapt to YOUR sky and YOUR eyes after 30+ sightings
• Adjustable satellite limit for smooth performance on any phone
• Works offline once data is loaded — perfect for trips to dark-sky preserves

★ PRIVACY & PERMISSIONS
We use your location only to compute satellite passes overhead. No tracking, no third-party data sharing. Camera is required for the AR view; microphone is requested only if you opt in to record.

A favorite of amateur astronomers, satellite spotters, and curious sky-watchers worldwide. Download Satellite Tracker today and never wonder "what was that?" again.
