Galileo
Operated by European Union
Data current as of 2026-07-20.
Galileo is the European Union's civil satellite navigation system, run through the EU Agency for the Space Programme and ESA. Its satellites orbit in medium Earth orbit and provide global positioning independent of GPS and GLONASS.
Galileo accounts for 3 cataloged objects, of which 2 are in orbit and 2 are active. 1 have reentered. The first launched in 1989, the most recent in 2025. The busiest year was 2025, with 2 added. Most fly near a 54-degree inclination with an orbital period around 845 minutes.
