  1. Earth Observation space systems - Thematic Centers- WGISS-2009 D. Roumiguières

  2. Outline • Thematic centre role in space systems • CNES Earth Observation missions and Thematic centres • Thematic centre functional environment • Thematic centre partners

  3. E-Phase functional architecture breakdown (space system operator point of view) Routine Mission Operation phase (Starts after satellite in-orbit commissioning ) Space System Management (operate, maintain & adapt) Mission Data exploitation Users community, Services Space segment Mission segment Cal Val - Mission Programming Center - Mission Data receiving network - Data storage/archiving - Data processing (low levels, sensor dependant) - Data Quality control - Performances monitoring - Processing improvements - Satellites / payload - Command Control Center - CC ground stations network • Users community interface • Data / products dissemination • Users feedback

  4. CNES Earth Observation missions Space System Management (operate, maintain & adapt) Mission Data exploitation Users community, Services Space segment Mission segment Cal Val Payload/Sensor oriented Thematic oriented Earth Observation systems Thematic Centers Images Altimetry Sounding Spot, VGT, Hélios, Pléiades, Venµs POSTEL ICARE Jason 1, Jason 2, Envisat, Doris, Cryosat2,AltiKa, HY2 ETHER Polder, Parasol, Calipso, IASI, SMOS,Megha-tropiques AVISO/IDS … • - One space system may feed several Thematic Centers • - One Thematic Center may use data provided by several space systems

  5. Space systems data Users Thematic Center Added value products In-situ data • The Thematic Center is an assembly point for : • Space system data • In-situ data • Computational models •  The added value products are the integration of these 3 elements • The Thematic Center collects users feedback to : • Improve interfaces and products dissemination • Improve products performances • Develop new products and services • The thematic center may be involved in CALVAL process (doted arrow) Models Users feedback

  6. Thematic Centers / Partners • - CNES is mainly involved in space data providing, other data and models being provided by partners • - CNES and partners work together at • Added value products development • Data dissemination • Users feedback loop activation.
