3. 3 Oxygen: Open and Operational Ground Segment

4. 4 The need from the user view point Today >83% of the EO data users, access data from more than 1 instrument/satellite close to 90% require other auxiliary data (e.g. met. or ground truth data) to process/correct the satellite data 80% of the users continue I.e. have established interfaces, tools procedures Today a lot of missions, instruments, data, tools, information off-the shelf technology exists However no coherent access technically no common international policy for data access and use Everybody only knows parts ; Users know even smaller parts Services providers spend up to 40% of their time getting access to data rather than providing the services Demand Resources Access Service

5. 5 Phase 1 (1980-1990) ESA to develop Europ. Technology for EO Data access Earthnet Programme Phase 2 (1990-2002) Large nationally funded infrastructure developments ESA to enable & support such national developments in the context of its and other individual missions Phase 3 (2003-2010) Develop global EO based service (independent of the space mission) Convert and tune infrastructure overcapacity to service needs Reach sustainability of services, benefits & budgets (existing operations to become more efficient) Benefit from now available off-the shelf technology (less development) Networking technologically and programmatically incl SMEs, contingency agreements among operators International EO standards Internationally agreed EO policy PDS technological evolution

6. 6 Oxygen: Why and how 1.User need for coherent access 2.Financial evolution requires to increase cost efficiency Smaller programmes reduced budgets Attract transition from research to other funding 3.Technological evolution leading to new ground segment partners and layout Co-ordination between partners Standardization Reuse of already available infrastructure

7. 7 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

8. 8 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
