Turn your phone into the ultimate AR Sky Guide. Identify lights in the night sky instantly. Whether tracking the International Space Station (ISS), watching a Starlink train, or identifying Constellations, Satellite Tracker provides professional-grade data with a stunning interface. NEW: AR STARGAZING MODE Stop guessing where to look. We've expanded our Augmented Reality view to include the stars! Identify Stars & Constellations: Align your phone to see constellation lines and star names drawn over the real sky. Satellite AR: Spot the ISS, Hubble, and thousands of satellites with precise zenith alignment. Unified View: See how satellites move through the constellations in real-time. NEW: AUGMENTED REALITY (AR) MODE Stop guessing where to look. Activate the AR Sky View and point your camera at the sky. The app overlays the exact position of satellites, the ISS, and celestial objects directly on your screen. Align the zenith arrow and spot objects in seconds. CORE FEATURES: Live Sky Radar & 3D Globe Visualize Earth and its orbiters like never before. Switch between a 2D Radar Scope for polar plotting or a stunning 3D Interactive Globe to see satellite trajectories relative to the Earth's day/night line. ISS & Starlink Tracker Get precise Pass Predictions. We calculate flyovers specifically for your location using the latest SGP4 propagation data. ISS Spotter: Know exactly when the Space Station will rise and set. Starlink Trains: Track the famous "string of pearls" satellite constellations. Notify Me: Set alerts for the next 2 hours or next 6 hours so you never miss a visible pass. Massive Database (NORAD/TLE) Access a catalog of over 12,000+ objects. From active weather satellites to space junk and classified bodies. Search: Find objects by Common Name or NORAD ID. Classify: Color-coded filters for LEO, MEO, GEO, and HEO orbits. Live Telemetry: View real-time altitude, velocity, range, and doppler shift. Power User Tools Offline Mode: Heading to a dark-sky preserve? Predictions work without internet access. Device Optimization: Adjustable "Satellite Limit" to ensure smooth performance on any device. Download Satellite Tracker today and join the community of sky-watchers. Never ask "What was that light?" again.
