Galileo program

First called GNSS-2 or Galileosat

The Galileo satellite navigation system will consist of a total of 30 spacecraft in three planes in medium Earth orbit, which will each be occupied by nine satellites, and with three spares satellites distributed on the three orbital planes. At an altitude of 23,616 kilometers and an inclination of 56 degrees, the system will provide accurate positioning data to users as far north as 75 degrees longitude.
Before this system is operational, the EGNOS payload (European Geostationary Navigation Overlay Service) will be included in Artemis and 2 Inmarsats. It will send signals that will be used to enhance GPS measurements.
