Supply Chain: ESA > AIRBUS DS > CS Group SPACE

Context

ESA, Airbus DS, Werum, CS Group Romania, CS Group France

CS Group responsabilities for ESA CSC Reference System (RS) are as follows:

• Development of infrastructure, monitoring and Sentinel 2 processing chain ; IVV for all satellites ; Setup of the Github collaborative platform ; Support to Operations

The features are as follows:

• The reference system service provides 3 operational functions: systematic production and distribution service; Ad hoc production and distribution service; Environment to ensure the test, integration, validation, benchmarking of Sentinel data processors
• IVV of all developments: infrastructure / monitoring / security / production chain S1, S2 and S3

Project implementation

The project objectives are as follows:

• The RS is a key component of the CSC Ground Segment: it provides to the community a complete and open source processing and distribution environment software.
• Integrated with the Sentinel Data Processors, it has the capacity to substitute the nominal CSC Production and Distribution services.

The processes for carrying out the project are:

• Agile, Continuous integration, DevOps, DevSecOps, GitFlow, Licence compliance

Technical characteristics

The solution key points are as follows:

• Event-Driven architecture
• Micro-Service Architecture
• Independent deployment solution of the supplier
• Hardené Kubernetes platform
• Management of access and identities
• Indicator management (PI/KPI)
• High performance logs & audit
• Siem
