UCS Satellite Database

This database from the Union of Concerned Scientists is a listing of operational satellites currently in orbit around the Earth. The database includes basic information about more than 800 satellites and their orbits, but does not contain the detailed information necessary to locate individual satellites. Users can find information about a particular satellite; identify sets of satellites having a common characteristic, such as altitude or mission; and sort or aggregate data about the whole population of satellites.
