3. CNES main strategy Serving Society • Access to space • Sustainable development • Civil applications • Space Science – preparing the future • Security and Defence • ESA or National program • (including bi-multi lateral cooperation)

4. CNES Operational Activities • CNES Space Operations • - Low Earth Orbit satellites • - Geostationary satellitepositioning and station keeping • - Mission Control Centres • - Navigation : EGNOS, Galileo • - ATV-CC • Station Network andMultimission Facilities • Preparation of new missions/concepts : autonomy, formation flying • Space Debris

5. Space Operations in CNES (1/6) Low Earth Orbit (14 satellites in orbit) Sustainable development : Earth Observation : Spot satellites Oceanography : Jason1 (Proteus) Climate Monitoring (A train) : Parasol (Myriade), Calipso (Proteus) Earth Electromagnetic Environment : Demeter (Myriade) Space Science Astronomy : Corot (Proteus) Security and Defense Earth Observation : Helios satellites Constellation : Essaim(4 satellites) (in preparation) Jason2 : oceanography Smos : Soil Moisture and Ocean salinity Pleiades : Earth observation Helios2B : Earth observation for defence Elisa : Electric intelligence Picard : Solar physics and climatology satellite Microscope : fundamental physics project & several still in phase 0 or A

7. Space Operations in CNES (2/6) • Geostationary telecommunications satellites • Telecom2 satellites (2 satellites in orbit) • LEOP operations : for CNES (national satellites), national or international organisations or industry • more than 50 satellite positioning operations completed to date • (in preparation) • Athena in cooperation with Italy for Defence • Mission control Centres • For science : for programming the payload or the mission (e.g : Rosetta, Cadmos, Corot) or for processing data to be distributed to scientific community (e.g : Doris, Altimetry, Polder, Cluster, etc) • For civil applications : French Mission center for Cospas/Sarsat (search & rescue) or EGNOS (navigation) • for sustainable development application by receiving mission data (through associated receive antenna) preprocessing and sending to users/scientific : Demeter, Parasol, Altimetry,etc • (in preparation) • Sevaral related to satellite/mission to be launched

8. Space Operations in CNES (3/6) • Navigation • EGNOS : European Geostationary navigation Overlay System : improvment GPS performance by augmentation • Hosting entity and operator with French Civil Aviation authority of EGNOS PACF (Performance Assessment and Checkout Facility) which handles all system operations and check its performance • Hosting entity for EGNOS components (reference stations in French Guyana, South Africa and France) Galileo : expertise, performance monitoring, LEOP in conjunction with ESOC

9. Space Operations in CNES (4/6) ATV-CC operations control centre for European cargo spacecraft designed to resupply the International Space Station • The ATV-CC is the main control centre for the Automated Transfer Vehicle (ATV). ESA has tasked CNES with developing and operating this centre, located at the Toulouse Space Centre. • The ATV-CC will operate and coordinate all ground facilities involved in ATV operations, working closely with control centres in Houston and Moscow • The Toulouse Space Centre will have mission responsibility throughout the ATV flight and ISS rendezvous phases, and on the ATV’s return (during the de-orbiting phase). • First launch is scheduled end 2007 on Ariane 5 from Kourou

10. Space Operations in CNES (5/6) Operational facilities 12 dedicated or multimission satellites or mission control centres 4 S band TT&C ground stations (multimission) 1 Operational Orbitography Centre 10 dedicated or product line TT&C antenna (S, Ku, X) 3 main control rooms for critical operations (LEOP)

11. Flight Operations in CNES (6/6) In preparation and the future • Autonomy : on orbit control (demeter), and R&D actions • Formation flying : r&D, Phase A SimbolX • Space Surveillance • Included in our orbit control activities • However some works are in progress to get a more operational facilities at French and/or European Level • Close approach monitoring for satellites under our control • by a debris • by a satellite non controlled by CNES • between our satellites • Collision risks monitoring • Collision risks screening • Collision risk management • Management of close approach • Atmospheric reentries of satellite (ATV, IADC exercice) • Launch collisions risk prediction

12. Mission model

13. To succeed in our missions in due quality and time To optimize our human/financial resources To integrate in our ops organisation how to keep knowledge/expertise on very old satellite with regard to attraction to new satellite or mission very challenging To meet as much as possible the international recommendation for the end of life satellite (re-deorbiting, passivation, etc) even for old satellite not designed for that To complete the interoperability for our ground station network (CCSDS SLE) Space debris : To improve the process for dealing with “close approach / collision risks” Preparation of the future New missions (innovation, risk, synergy, etc) Impact of the on board autonomy Impact of the flying formation Challenges
