Satellite Tracker 3D Sky Radar

Satellite turns the night sky into a live, interactive map. Watch the International Space Station, Starlink trains, Hubble and thousands of satellites orbit Earth in real time on a beautiful 3D globe — then step outside and actually spot them.

Powered by a first-party SGP4 orbital engine and live public data from CelesTrak, NOAA and The Space Devs, Satellite computes exactly what's visible from where you are, the moment it happens.

A REAL-TIME 3D GLOBE

• A photoreal Earth (NASA Blue Marble) with day/night, drifting clouds and city lights

• Every tracked satellite orbiting live at its true position

• Tap any satellite to see a 3D model, its orbit path and live telemetry

• Multiple globe styles: Realistic, Night Lights, Vector, Minimal — with cloud, ring and orbit layers

• Pinch to zoom, drag to spin around the planet

NEVER MISS A PASS

• Personalised visible-pass predictions for your exact location

• Rise/peak/set times, direction, max elevation and brightness

• Tiered reminders — a heads-up 30 minutes before, then "go outside" minutes before the pass

• Add any pass or launch to your Calendar with one tap

• Knows when a satellite is sunlit vs. in Earth's shadow

PLAN TONIGHT — IS IT WORTH GOING OUTSIDE?

• A Stargazing Score that blends darkness, the Moon and cloud cover into one number

• Live darkness countdown — astronomical night start/end, sunset and sunrise

• Moon phase, illumination and rise/set times, all computed on-device

• Tonight's visible passes and an aurora heads-up when the Kp index spikes

LIGHT POLLUTION & DARK-SKY MAP

• See the Bortle class, sky brightness (SQM) and limiting magnitude for any spot

• Built on a bundled VIIRS-derived world atlas — works fully offline

• Pan the map to scout darker skies near you before you drive out

SUN & MOON TRANSITS (astrophotographers, this one's for you)

• Find when the ISS or any satellite crosses the face of the Sun or Moon from your location

• Precise timing and angular separation, computed entirely on-device

SKY EVENTS CALENDAR

• Upcoming meteor-shower peaks, solar and lunar eclipses, and Full/New Moons

• Countdowns so you can plan ahead

RED NIGHT MODE

• A full-app red filter that protects your dark adaptation at the eyepiece

SKY VIEW (AR)

• Point your phone at the sky and see satellites as 3D models, labelled, exactly where they are

• Identify mode: aim the reticle at a light to find out what it is

ROCKET LAUNCHES

• Upcoming launches worldwide with live countdowns

• Launch-pad maps and Live Activities on your Lock Screen

• Track SpaceX, NASA, ULA, Arianespace, ISRO and more

SPACE WEATHER & AURORA

• Live planetary Kp index with a 3-day forecast and solar-wind speed

• Aurora viewing chance calculated for your latitude

• Beautiful charts powered by real NOAA SWPC data

EXPLORE THE CATALOG

• Search 300+ satellites: stations, Starlink, weather, navigation, science and the brightest objects

• Notable Objects — jump straight to the ISS, Hubble, Tiangong and other icons in orbit

• Find Starlink: see Starlink passes by your location or any coordinates

• ISS Live: a NASA live stream plus who's currently aboard the ISS and Tiangong

• Favorites and custom Collections, synced across your devices with iCloud

BUILT THE RIGHT WAY

• Works offline with cached data; refreshes when you're online

• Widgets for your next pass and space weather

• Apple Watch app and Siri Shortcuts

• Your location never leaves your device

Whether you're a casual stargazer hoping to catch the ISS, an astrophotographer planning a shoot, or a space enthusiast who never wants to miss a launch - Satellite is your window to everything above.
