Satellite Trackers Real-Time Orbital Tracking
Track space stations, mega-constellations, navigation satellites, space telescopes, deep space missions, orbital debris and atmospheric re-entries in real time. From LEO to Voyager in interstellar space — live position, altitude, speed and orbital path updated every second.
The ISS orbits Earth at approximately 420 km altitude, completing one orbit every 90 minutes at 28,000 km/h. Track its exact position, crew manifest and upcoming visible passes.
Space Stations
Crewed orbital laboratories in low Earth orbit. Track each station's live position, altitude, speed, crew manifest and upcoming visible passes from your location.
Mega-Constellations
The largest satellite fleets in orbit — broadband internet constellations deploying thousands of spacecraft in low Earth orbit. Track every satellite in each fleet, monitor launch cadence and constellation build-out progress.
Space Telescopes
Track the world's most powerful space observatories — from Hubble in low Earth orbit to JWST at the L2 Lagrange point 1.5 million km away. Live position, current observation targets and image galleries.
Track any of 18,000+ satellites individually via the Satellite Directory →
Deep Space
Track spacecraft beyond Earth orbit — from the inner solar system to interstellar space. Live 3D solar system map with real-time positions powered by JPL Horizons ephemeris data and NASA Deep Space Network status.
Individual missions: Voyager 1 · Voyager 2 · Tesla Roadster · Parker Solar Probe · Europa Clipper
Debris & Re-entry
Monitor orbital debris distribution and track objects predicted to re-enter Earth's atmosphere. Includes risk assessments, predicted windows, and historical re-entry data.

What You Can Track on Orbital Radar
Orbital Radar provides free, real-time satellite tracking for every catalogued object in Earth orbit. Our tracking engine uses Two-Line Element sets (TLEs) from the US Space Force's 18th Space Defense Squadron combined with the SGP4/SDP4 propagation algorithm to calculate each satellite's position, altitude and velocity — updated every second directly in your browser.
From the International Space Station orbiting at 420 km to GPS navigation satellites at 20,200 km in medium Earth orbit, every tracker shows live telemetry, orbital path visualisation, pass predictions for your location and detailed mission context. The Starlink Tracker monitors SpaceX's rapidly growing broadband constellation — the largest satellite fleet ever deployed — while our Space Debris Map visualises the growing challenge of orbital debris across all orbital regimes. The Deep Space Tracker extends far beyond Earth orbit with an interactive 3D solar system map showing real-time positions of 25+ spacecraft — from Voyager 1 in interstellar space to Parker Solar Probe skimming the Sun — powered by JPL Horizons ephemeris data and live NASA Deep Space Network status.
Beyond individual trackers, the Satellite Directory lets you search and track any of the satellites in our database individually. The Satellite Maneuver Tracker detects and classifies orbit changes across the full catalogue — from Starlink orbit raises to military satellite plane changes — with a strategic watchlist monitoring inspector satellites and proximity operations in real time. Pair any tracker with Satellite Pass Predictions to know exactly when a satellite will be visible from your location, complete with sky charts, brightness estimates and countdown timers.
