Future Core Ground Segment Scenarios

Future Core Ground Segment Scenarios Pascal Gilles EOP-G Ground Segment Coordination Body Workshop 2015 ESRIN, 24 September2015 Ground Segment Coordination Body Workshop 2015 ESRIN 24 September2015 Pag. 1

Reasons for Change: Programmatic Programmatic End of in-orbit life of major ESA EO satellite missions (Envisat, ERS ) Budget composition and scales are changing: overall increase over years to come but decrease in ESA member states budgets and increase in EU budgets linked to Copernicus where focus is on provision of data to service providers designated by EC. End of EOEP funded mission operations and transition to LTDP. Ground Segment Coordination Body Workshop 2015 ESRIN 24 September2015 Pag. 2

Reasons for Change: Industry & Technology Trends Industry & Technology Trends Maturity of industry and technologies; increased appearance of service offerings. Mature IT and communications sector looking for opportunities also in EO. Aggressive stance of Google and appearance of initiatives from other, non-european Google type Cloud Service Providers mainly focussed on data/products. New media and channels for communication with user communities: Cloud, Social media, Link EO data. Ground Segment Coordination Body Workshop 2015 ESRIN 24 September2015 Pag. 3

Reasons for Change: Operations concept Missions profile From Envisat type missions to Earth Explorers type missions Smaller Focus on science Maturity of instruments requires technical and schedule flexibility Data Management User driven mission planning to systematic acquisition and limited mission planning (e.g. calibration, housekeeping) Systematic processing vs delayed on- processing Cyber Security protect data integrity and avoid data loss. Growing & Evolving customer community Science communities not in focus of currently funded GMES ground segment but called upon nationally to help deliver benefits of GMES. Application and service industry looking for improved to data/products. Ground Segment Coordination Body Workshop 2015 ESRIN 24 September2015 Pag. 4

ESA UNCLASSIFIED For Official Use AWG - 12th March - Page5 ESA EO GS Operations Concept Evolution: Objectives Improve the availability and facilitate the exploitation of data Better serve a broader user community Improve the overall missions operability, reliability and availability Sustainably reduce operating cost to meet budget constraints Ensure preservation and of data and associated information in the long term Develop advanced tools supporting such functions/processes. Leverage technological evolution and continuous decrease of HW costs Use commercially available (European) products whenever possible Standardise, streamline and simplify interfaces to support modular concepts

ESA UNCLASSIFIED For Official Use AWG - 12th March - Page6 ESA EO GS Operations Concept Evolution: Core features of the target concept One core EO GS Reference Operations Concept for all ESA and TPM missions Modularity and flexibility: can be tailored as necessary to meet individual mission needs Compatible with historic (ERS/Envisat/TPMs), current (Sentinels, Earth Explorers, TPMs) and future EO missions Definition of the reference operations concept based on the following principles: Limit HW procurement (e.g. rely on IAAS type services) and focus on Streamline, simplify and standardize interfaces between functional blocks with a view of minimizing dependencies between those blocks and allow maximum flexibility for theit implementation Focus on long term data and associated information preservation, curation and The CORE PDGS shall be one of the elements fuelling the future network of Earth Observation Community Platforms

Procurement Terminology Operations contract: classical contract for an operational facility (e.g. PACs or Stations) where ESA is deploying own HW and SW in the facility and places a contract with the facility owner to operate these systems Service Contracts: contract where the Contractor executes ESA-defined processes for the activities in scope under agreed levels of quality and performance (Service Level Agreement). While ESA is defining and enforcing the appropriate technical requirements, e.g., on equipment compatibility, interfaces, performance, security and reliability, it is the Prime Contractor s responsibility to propose and manage a Consortium and to deploy the necessary means, including adequate infrastructure and competences, to provide the abovementioned services (i.e. ESA will refrain to impose or provide any technological platform or CFIs).
