2 European Ground Systems Common Core (EGS-CC) Joint undertaking led by ESA (ESTEC & ESOC) together with European Primes and National Space Agencies. EGS-CC & ASI K. Hjortnaes/N. Peccia ESTEC/ESOC 28/11/2013 Slide 2

3 Background Within Europe, different monitoring and control systems are used by different organisations; Some of them are common to Mission Operations and Spacecraft Assembly, Integration and Testing (AIT), most are specific. Often multiple systems are used even within the same project by different companies or at different levels (e.g. payload/system) or at the different development phases. Little synergy across missions and mission phases. Difficult to exchange data and procedures between the various stakeholders. Many of the existing systems are reaching their end of life Become excessively complex with time Use old software technologies and hardware platforms Are difficult to maintain and modernise 3 EGS-CC & ASI K.

4 The EGS-CC Motivation 1. To develop and maintain a European Ground System Common Core (EGS-CC) for the next generation MCS/EGSE systems for the benefit of end-to-end usage (AIV/OPS) 2. Ensure interoperability of facilities between project phases and between programs (institutional and/or commercial). 3. Ensure a maximum commonality between EGSE and MCS, including common data and procedures. 4. Support the competitiveness of European Industry when supplying end-toend space systems on the world market. 5. Allow small and medium enterprises ( non-lsi") to operate in a product oriented market, supplying quality products within a standardised context. 6. Profit from the cost benefit of one common core, by sharing development, validation, sustaining and maintenance. 7. Cost and risk reduction when implementing space projects. EGS-CC & ASI K.

5 Schedule 2009; request from industry to address the approaching EOL of existing Ground Support Systems (MCS/EGSE) ; Harmonisation meetings involving ESA, the Large System Integrators, the National Agencies to define and agree on the perimeter of a collaboration to develop a European Ground System - Common Core. Jan ; System definition (Phase-A) Partners ESA (ESTEC and ESOC) CNES DLR UKSA Astrium Satellites & Astrium Space Transportation OHB Systems ThalesAleniaSpace - France and Italy ASI has been invited to join (expressed interest but wanted to wait due to lack of resources) EGS-CC & ASI K.

6 Commitments All parties considered it of strategic importance. Memorandum of Understanding for initial phase was drafted and signed Commitments include: The development of the EGS-CC shall be done in open competition following the normal ESA procurement process and favouring the role of the SME s for the implementation phase. Adoption of the EGS-CC for institutional missions Adoption of the EGS-CC for commercial missions after successful validation in institutional missions An extended Collaboration Agreement has been drafted during 2012, reviewed by all stakeholders legal departments and is in the signature loop.
