  1. Considerations for a European Global System Enrico Saggese Senior Vice-President forSpace Activities Coordination

  2. 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

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

  4. OBSERVATION: COSMO-SkyMedItalian Contribution to GMES A Spaceborne Dual Use Earth Observation System for Defence/Intelligence and Commercial Applications

  7. 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

  8. 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)

  9. COMMUNICATIONS: US TSAT Key Features Other Satellites • 5 ball constellation • Launch FY13 - FY17 • Lasercom crosslinks • Efficient radio frequency (RF) links (XDR+) • Packet based network • Dynamic allocation • Comm-on-the-move (COTM) • Protection against jamming, nuclear effects, detection Multi-access lasercom Airborne lasercom terminals Terminals Terrestrial Infrastructure COTM 1’ tracking antenna Network standards and interfaces High rate terrestrial networks and ground infrastructure Information assurance (Covers all segments) Robert M. Shea LtGen, USMC

  11. Communications Navigation Secure TLC Survey Space and Security: an integrated system Observation Meteo Intervention Cartography Alarms and Localisation Risk assessment Data Gathering

  12. 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
