Overview
Europe's civil global navigation satellite system — owned by the EU and operated through EUSPA, with ESA as the design and procurement agent — offering high-accuracy positioning independent of GPS.
Member satellites
Individual members of large, fast-changing constellations are not enumerated here — their rosters change continually, and this encyclopedia does not invent a fixed list. The constellation is modelled as a single entity connected to its operator and orbit.
