AVISO/IDS

  • - One space system may feed several Thematic Centers

  • - One Thematic Center may use data provided by several space systems

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

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.
