Customer: Centre National d’Etudes Spatiales (CNES)

Programme: SWOT

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for CMP IVV, support in Technical and Operational Qualification and LEOP of SWOT mission are as follows:

• • Piloting of the IVV by CS GROUP, TQ/OQ tests by CNES

The features are as follows:

• AIV: development of LdP procedures and assignment, definition of strategy, plans and automated execution of tests (AIV tools for managing contexts, results, requirements) QT/OQ System Tests: preparation and support for the execution of compatibility/QT/OQ tests, development of ground operational procedures Support to Operations: resources integrated into the CNES teams for launch, in-flight acceptance and start of life (shifts, ground constraints)

Project implementation

The project objectives are as follows:

• Engineering assistance and support for the implementation of the system integration and qualification of the SWOT Satellite Posting and Maintenance Center implementing the ISIS Product Line
• ISIS missionization and integration on science cluster

The processes for carrying out the project are:

• Requirements management (STB, IF): Testlink and Excel
• Specific Process for Assembly, Integration, Validation Qualification of Control Ground Segments
• Qualification system tests of control ground segments: Compatibility, Technical and Operational Qualification

Technical characteristics

The solution key points are as follows:

• Configuration and deployment of CMPs: Nominal, Standby, SCP/SSV (experts) and test lines
• Operational qualification TM/TC ISIS chain: BDS configurations, sessions, SLE, COP, catalogs, TM visualization, TC histo
• Implementation of ISIS operational concepts: procedures, automation
• Experienced AIV team for rapid upskilling
