Ground Segment Coordination Body (GSCB) Status, Objectives and Workplan

1 Agenda • Why Ground Segment Coordination? • GSCB: what we are, who we are • GSCB organisation and tasks •Achievements • More work ahead

2 Why GSCB • Increasing number of EO missions and operating entities • Demand for EO data has evolved dramatically in the last decade – Amount and volume have increased by a factor 10 – More than 80% of the EO data users request and use data from more than one satellite • For GMES Space Component Programme (GSC) collaboration is essential in the sustainability of the EO data supply assured with a fleet of European EO satellites – Operational and sustainable user services – Avoid unnecessary duplication in technologies •Harmonizationof the various approaches in interfacing the user community and in the PDGS operations and engineering • Cooperation in the ground segment development, the operations and the data exploitation

EE OO AA pppp Ground ll ii Segment caca Harmonisation tt & ii oo Coordination nn ss

• In 2004, ESA's EO Programme Board ground segment task force revised the strategy to deal with these challenges in the EO ground segment

• It recommended cooperation and coordination among member states investing in and managing EO Payload Data Ground Segments

• Creation of the Ground Segment Coordination Body (GSCB) in June 2005

8 GSCB Membership

• Representation of the owners and holders of European and Canadian EO data and associated infrastructure – initially key institutional organisations (ASI, CNES, CSA, DLR, ESA, Eumetsat) – managing their EO ground segment operations and development

• ESA : – Provides secretariat support – Participates in all tasks and working groups – Uses this group as the main Ground Segment Coordination mechanism among Member States (ESA convention art. II.c)

9 Institutions and missions involved

10 GCSB Organisation

• Permanent consultation group

• Quarterly meetings

• Yearly report

• Ad-hoc technical working groups – When required by members to elaborate, review and recommend specific technical issues

• Workshops – Consultation of the wider EO Community, including the EO ground segment industry

11 Scope of the group

• Adoption of a common, coordinated and cost-effective approach on EO ground segment issues

• Facilitate exchange of information, discussion and agreements

• Define and propose: – operational cooperation schemes – agreements for sharing or exchange infrastructure and data – technical standards in the management of their EO data and the related ground segment infrastructure

• Members to provide recommendations to their respective programmatic bodies for implementation

12 Tasks (1/2)

• Ensure technical and programmatic coordination of all European activities concerning Earth Observation ground segment development and operation (e.g.: elaborate a common strategy for long term archiving- which data and how, set up contracts or projects inside and across their respective data holdings, Identify and report on different ground segment setup standards or approaches)

• Build agreements to share operations resources and existing infrastructure for the benefit of the user community (e.g.: Set up a network of mission planners and order desks, data can be held in other’s archive)

13 Tasks (2/2)

• Standardise the ground segment modules, its interfaces and the programmatic Service Level to access the different EO data sets to: • Serve service providers in an harmonised way • Serve the European scientific and commercial Earth Observation users • Provide a unified European technical standards and interfaces and approach towards GEOSS. • Easy the implementation and integration of new missions and EO data

• Monitor the implementation and results of the adopted jointly defined guidelines in the different GCSB members

• Recommend policy and programmatic issues as needed towards the respective bodies

15 Work Plan (2006 – 2008)

• Payload Ground Segment reference architecture • Interoperability – Heterogeneous Mission Accessibility (HMA) – harmonised access across heterogeneous missions • Common Strategy for long-term Earth Observation data preservation • Sharing of telecommunications networking infrastructure, both ground and satellite network • Sharing of design and technologies – Security requirements implementation – Data description, manipulation and generation • Coordinate and liaise with other coordination bodies (GEO, CEOS) • Liaison with standardisation bodies and initiatives (OGC, CEN, INSPIRE). – GSCB does not act as a new standardisation body. – identify and promote the use of a common set of standards

16 Achievement: Interoperability (HMA)

18 Achievement: Operations concept sharing • common Strategy for long-term Earth Observation data preservation – technical and managerial approach – data logistics, data access, security and archive operations, maintenance and evolution – including, data reprocessing and the data integrity – capitalise on policies already in force for preserving digital data archives (at ESA, national space agencies, EUMETSAT) – consider European Union initiatives like the CASPAR project – first draft proposal commented in GSCB and ESA DOSTAG – ESA long-term data preservation strategy, inspired in this draft proposal, to be presented to DOSTAG in 2007

• Sharing of telecommunications networking infrastructure, both ground and satellite network – cost-efficiency for the ground segment operators – cost-benefit of procuring higher capacity network infrastructure, aggregating the need from different EO operators, versus independent procurements – sharing concept and operational scenario to set-up the agreements among the different EO operators and the networking service provider – First case: data repatriation of EO data acquired in the Antarctica X- band acquisition stations to Europe. – Demonstration between ESA, KSAT (Troll Station) and DLR (O’Higgings Station) at end 2007 19 Achievement: PDGS reference architecture • identify the PDGS building blocks and its interfaces – reusing the experienced of the different ground segment owners and of industrial entities

• identify, eventually define, publish and recommend the adoption of the reference architecture for EO ground segments

• for a simple, user friendly, cost-efficient and inter-operable infrastructure to: – Ease the implementation and integration of new missions and EO data – Ease competitiveness in ground segment compatible elements development by industry – Serve the European EO data user community in an harmonised way. – Provide a unified European technical standards and interfaces and approach towards GEOSS.

• Workshop Information Sessions on: – Ground Segment architecture and operations concept – Security requirements implementation – Data and interface representation tools

20 Next Steps in the Work Plan

• EO Interoperability standards –First implementation for 2009 in the GMES Space Component – Definition of the harmonised EO data product formats and their quality certification – Implementation extensions and promotion into GEO

• Ground Segment standard architecture (building blocks and interfaces) – Consolidate high level architecture – Step-wise approach to interface standarisation: Select the main interfaces through this workshop • Common Strategy for long-term data preservation – ESA proposal to DOSTAG – Publish the Common Strategy paper

21 Conclusions

• The Ground Segment Coordination Body was created to: – Exchange information amongst mission developers in Europe and Canada – Harmonise the development of ground segment activities and optimize use of infrastructure – Ensure easy access to the maximum data available for a wide variety of users

• GSCB has to cope with the challenges of different national and programmatic policies – Dealing with public and private systems – Bringing together systems already in operations with those still in the planning phase

• GSCB is not a standardization body, but is giving a significant push toward to the definition of ground segment standards

• GSCB is planning periodic information meetings where the key players in the ground segment industry and government are invited
