Considerations for a
European Global System
Enrico Saggese
Senior Vice-President for
Space Activities Coordination
EUROPEAN AMBITION for BEING GLOBAL in:
• NAVIGATION: Galileo
• OBSERVATION: Optical and Radar Constellations
with Ground Moving Target Indicator
•
COMMUNICATION: A dual use wide band global
satellite communication system including a
Data Relay System

SAR
Navigation
NAVIGATION: Galileo Services
Open Access
Free to air; Mass market; Simple
positioning
Commercial
Encrypted; High accuracy;
Guaranteed service
Safety of Life
Open Service + Integrity and
Authentication of signal
Public Regulated
Encrypted; Integrity;
Continuous availability
Search and Rescue
Near real-time; Precise; Return
link feasible

Then it is time for…
…a European Space Radar Constellation with:
• GMTI (Ground Moving Target Indication)
• Target detection and geographic localization
It has to allow:
• Global visibility
• High coverage per day
• High access time
• Few minutes response time

MTI
• MTI, preliminary antenna size for “4-90 Km/h” (X-band):
– Antenna size in the elevation plane from 1.2 to 1.6 m
– Total antenna size in the azimuth plane from 6 to 9 m
– Two receiving sub-apertures, with displacement of 3.0 to 4.5 m.
• COSMO characteristics compliant with this design, but:
– Development of advanced on-board processors and Rx/Tx modules
– Development of ground processing
• Full operational constellation:
– 15-20 LEO satellites
– 2 B€ operational system (recurring costs)

UE, ESA, Industry Roles
• UE will coordinate/complement National Systems to
operate a global network
• ESA develops required technology through
– Galileo
– Sentinels responding to EO needs of GMES program
– DRS program
– Artemis satellite operations
• Industry will compete for system manufacturing and
deployment
