2. Summary
• Global Navigation Satellite Systems, such as GPS,
GLONASS, Galileo and Beidou, constitute a worldwide utility,
tightly interconnected with all other critical infrastructures
(electric power distribution networks, air traffic management
systems, railways, water and oil piping networks,
telecommunications;
• EGNOS and Galileo are the key elements of the European
PNT “system of systems”, a strategic and critical
infrastructure of the European Union;
• EGNOS, the European Geostationary Navigation Overlay
Service, is already fully operational and providing services;
• The Galileo global navigation satellite system, joint initiative
by the European Union and the European Space Agency, is
one of the most ambitious and technologically advanced
service systems being developed in Europe, by European
industries and with European resources.

3. Resumen
• Los sistemas mundiales de navegación por satélite, tales como
GPS, GLONASS, Galileo y Beidou, constituyen una utilidad de
todo el mundo, fuertemente interconectada con el resto de
infraestructuras críticas (redes de distribución de energía
eléctrica, sistemas de gestión del tráfico aéreo, ferrocarriles,
redes de agua y tuberías de petróleo, telecomunicaciones;
• EGNOS y Galileo son los elementos clave del "sistema de
sistemas" Europeo de PNT, una infraestructura estratégica y
crítica de la Unión Europea;
• EGNOS (European Geostationary Navigation Overlay Service)
ya está en pleno funcionamiento y hace prestación de servicios;
• El sistema de navegación global por satélite Galileo, iniciativa
conjunta de la Unión Europea y de l’Agencia Espacial Europea,
es uno de los sistemas de servicios más ambiciosos y
tecnológicamente avanzados que se desarrollan en Europa, por
las industrias europeas y con recursos europeos.

GALILEO Program Essentials
• Galileo is Europe's initiative for a state-of-the-art global
navigation satellite system, providing a highly accurate,
guaranteed global positioning service under civilian
control;
• While providing autonomous navigation and positioning
services, Galileo will at the same time be interoperable
with GPS and GLONASS, the two other global satellite
navigation systems;
• The fully deployed Galileo system will consist of 30
satellites (24 plus 6 spare) and the supporting ground
infrastructure.

35. Galileo IOV – Ground Control
Centres
© Axel Schultes Architekten
2 Complementary Control Centres:
• Ground Mission Segment (GMS)
in Fucino has the responsibility
for the mission aspects ,
• Ground Control Segment (GCS)
in Oberpfaffenhofen, to control
and monitor the constellation.
Both centres will be completed
to become fully redundant.
