Live ISS Tracker & Real-Time Space Station Map
Live ISS Tracker
This is our live window on the International Space Station. The map updates in near real time: latitude, longitude, altitude, speed, visibility – plus a trace of where it's just been. It refreshes every few seconds so you're always current.
Watch the International Space Station move across the map in real time. The position updates four times per second so you see smooth, continuous motion.
Curious when you can see it over your location? Try our Next ISS Pass tool, it gives exact times, directions and brightness. Scroll on for the Earth video feed, data notes and answers to common questions.
Live 4K Earth View from ISS
Watch Earth live in 4K from Sen's video cameras on the International Space Station, downlinked via NASA. This is the world's first continuous 4K livestream from space, empowering you to see our planet like astronauts do. Note: The feed includes an orbital position overlay and automatic camera switching. Around 20 hours of live video daily.
About This Dashboard
ISSINFO is developed and maintained by Neil Johnson, a Software Engineer at Microsoft with 30 years of experience in IT and building real-time data systems, and Leo Johnson, an Astronomy student with a focus on orbital mechanics and space science outreach.
We built this tracker to provide accurate, real-time ISS tracking using professional-grade orbital propagation (SGP4/SDP4 algorithms) combined with authoritative TLE data from CelesTrak. Our goal is to make space accessible to everyone—whether you are a student, educator, amateur astronomer, or simply curious about what is orbiting overhead.

Satellite Tracker FAQs
How often is the ISS position updated?
The map updates four times per second (4Hz) giving you smooth, real-time tracking. You can click "Follow ISS" to keep the station centered on screen, and adjust your zoom level while following to see more or less of the surrounding area.
Can I track other satellites besides the ISS?
Yes! Click the Satellites button above the map to toggle Tiangong (China's space station), the Hubble Space Telescope, Landsat 9, NOAA-20 and Vanguard 1. Each satellite shows a colour-coded orbit path and live position. You can also get pass predictions for Tiangong and Hubble.
How accurate is the live map?
Ground track accuracy is generally within a few kilometres of the actual position. For visual spotting where timing matters, use the Next Pass page for local predictions.
Why might I not see the ISS even during a pass?
You need darkness or deep twilight while the ISS is still sunlit. Daylight passes and those when the station is in Earth's shadow are invisible to the naked eye.
Altitude vs elevation?
Altitude (around 400 km) is the station's height above Earth. Elevation in pass predictions is the angle above your horizon during a flyover.
Where do you get the data?
Live positions come from Two-Line Element (TLE) orbital data published by CelesTrak. We run these through an SGP4 propagator to calculate positions four times per second. Crew information comes from Open Notify, and country names use OpenStreetMap Nominatim. Thanks to these providers and the open-source community.
How can I plan my next sighting?
Head to the Next Pass tool. It auto-detects your location (or you can enter coordinates), lets you choose ISS, Tiangong or Hubble, and lists visible passes with direction, elevation and brightness (magnitude).
