Space Station Tracker vs The Einstein Archive

Track the International Space Station in real time and see upcoming visible flyovers for your location. ISS Tracker helps you understand where the ISS is now, when it will pass overhead, and where to look in the sky. It is designed to be simple, useful, and privacy-first. LIVE GLOBE VIEW See the current location of the ISS and its orbital path on an interactive globe. The app displays approximately one full orbit and updates the station’s position with live telemetry, including latitude, longitude, altitude, and speed in miles or kilometers. UPCOMING VISIBLE FLYOVERS Find upcoming ISS flyovers based on your location. Viewing opportunities are calculated using your location and estimated visibility, helping you identify passes that may be visible to the naked eye. FLYOVER COMPASS VIEW Use the compass view to know where to look. Each flyover includes azimuth, compass direction, and elevation details for the start, maximum elevation, and end of the pass. PRIVACY-FIRST LOCATION USE Your location is used to show your position relative to the ISS and calculate upcoming flyovers. Location is requested only while using the app, and is never sent to third parties. The app does not use analytics, advertising, or tracking. ISS Tracker is built for skywatchers, space enthusiasts, educators, students, and anyone who wants a clear way to follow the International Space Station. Questions or feedback?
