Jim Anning's International Space Station API

Jim Anning's International Space Station
The International Space Station API is a free web service built by developer Jim Anning. The API maintains a database of Two Line Element (TLE) data for the International Space Station (ISS). When a user makes a request, the API finds the nearest valid TLE and calculates the station’s location. The API returns the latitude, longitude, altitude, and velocity of the ISS at any given time.
