About ISTracker

ISTracker provides real-time International Space Station tracking using the Open Notify API. View the current position, crew members, and learn about the ISS.

The position is the latitude and longitude of the point directly below the station, cached for one minute. The crew list is whatever Open Notify reports for the ISS and is cached for an hour; it can trail real crew changes. Station figures such as altitude (about 408 km) and speed (about 28,000 km/h) are typical values, since the orbit decays slowly between reboosts. See the FAQ or ISS facts for more.
