About the tracker

Explore satellites on a live 3D map

TransitSatellite uses current orbital elements to calculate where tracked satellites are located above Earth. Positions are updated continuously in your browser while orbital data is refreshed periodically from the source catalog.

Select a satellite to view its altitude, velocity, latitude, longitude and trajectory. You can also connect your location to estimate upcoming passes and determine whether an object is above your horizon.

Current satellite positions

View calculated locations for space stations, scientific spacecraft, weather satellites and other tracked objects.

Interactive orbital paths

Select an object and follow its projected trajectory around the interactive Earth globe.

Satellites above you

Connect your location to calculate horizon visibility and estimate upcoming satellite passes.

Satellite tracker questions

Are the satellite positions live?

Positions are continuously calculated from current orbital elements. Orbital source data is refreshed periodically rather than received as second-by-second telemetry from each spacecraft.

Can I see which satellites are above me?

Yes. After granting location permission, TransitSatellite calculates the direction, elevation, distance and upcoming passes for supported tracked objects.

Does a predicted pass guarantee visibility?

No. Clouds, haze, terrain, buildings, light pollution and satellite brightness can all affect whether a spacecraft is visible with the naked eye.
