EUROPEAN AMBITION for BEING GLOBAL in:

• NAVIGATION: Galileo

• OBSERVATION: Optical and Radar Constellationswith Ground Moving Target Indicator

• COMMUNICATION: A dual use wide band global satellite communication system including a Data Relay System

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
