The Galileo system is satellite‐based navigation system currently under development by the European Union (EU). This development has completed definition and development phases and is nearly complete with launching operational satellites to achieve a 30 satellite constellation. Galileo operates in the L‐band with MEO satellites at height slightly above the GPS MEO satellites (23 222 km for Galileo versus 20 180 km for GPS). Galileo satellites operate in three orbital planes at an inclination angle similar to GPS. Galileo operates in three spectral bands known as E1 (1559–1592 MHz), E5 (1164–1215 MHz), and E6 (1260–1300 MHz).
