Oxygen: Open and Operational Ground Segment



The need from the user view point



PDS technological evolution



Oxygen: Why and how

  • User need for coherent access

  • Financial evolution requires to increase cost efficiency

      • Smaller programmes  reduced budgets
      • Attract transition from research to other funding
  • Technological evolution leading to new ground segment partners and layout

      • Co-ordination between partners
      • Standardization
      • Reuse of already available infrastructure


Oxygen Objectives (1/2)

  • Oxygen is a concept aimed at

  • Facilitating access to EO data from ESA and other missions

  • Increasing sustainability of EO data provision widening the range of offered data sources

  • Making the operations of EO missions more efficient



Oxygen Objectives (2/2)

  • Oxygen has started officially almost 2 years ago and is ongoing to enlarge the benefits of EO .

  • It has been preceded by a series of precursor activities aiming at ease the users’ life:

    • harmonization of the user client interfaces (EOLI based) in a Multi-mission environment
    • Introduction of standard state of the art technology e.g. Web Mapping or access to MUIS catalogue using XML/SOAP


EOLI – ESA’s Multimission EO Catalogue



Principles



Interoperability - harmonized data access



Mission independent and modular

  • PDS harmonization

    • Detailed definition of open architecture
    • identification of generic-common elements, specific mission elements and define standard interfaces
  • Evolution of existing system rather than new developments

    • Evolution of the common elements to integrate new missions


Implementation Plan



1st Phase (2003 – 2005)

  • Analysis of existing infrastructure

  • EO Web Portal for awareness of missions, user services, products, information and service providers

  • Service Support Environment: for easing provision of Services by Service Providers

  • Integrating upcoming EO National projects in Europe

    • Feasibility assessment at political, technical and programmatic level (Terrasar-X, Radarsat-2, Cosmo, Pleiades)
    • Pilot activities for interoperability between catalogues, order and online distribution systems (standards in SOAP/XML)


2nd Phase (2005-2006)

  • Prepare the ‘EO Data Access Component’:

    • Define the interoperability Standards for the harmonized access to heterogeneous missions
    • Co-ordination with the major satellite owners / industry
    • integrate the national missions and other non-European missions to respond to user needs for access to ‘maximum number’ of mission data

  • re-uses all components of the INFEO initiative (JRC/CEO) and adds new features

  • comprised of sub-sites to provide access to various data types

      • directory of resources
      • calendar
      • maps
      • catalogues
      • services …


2) Simple interoperable catalogues
