Cnes main strategy l.jpg
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)


Cnes operational activities l.jpg
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


Space operations in cnes 1 6 l.jpg
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


Space operations in cnes 2 6 l.jpg
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


Space operations in cnes 3 6 l.jpg
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


Space operations in cnes 4 6 l.jpg
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


Space operations in cnes 5 6 l.jpg
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)


Flight operations in cnes 6 6 l.jpg
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



  • Challenges l.jpg

    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
