Context

CS Group responsabilities for Sentinel-2 Mission Performance Center are as follows:

• Service management,
• ESL (Expert Support Laboratories) Coordination,
• ESL L1 Radiometry Lead,
• L1 Processor Prototyping (S2 IPF),
• L2A Processor Packaging (Sen2Cor),
• Tools Maintenance (QCC).

The features are as follows:

• Calibration – update on-board and on-ground configuration data to meet product quality requirements
• Validation – assess the quality of generated data products
• Quality Control – routinely monitor sensor status and check if derived products meet quality requirements along mission lifetime
• Data processors evolutions definition
• L2A Processor&Tools corrective and perfective maintenance – manage updates of Sen2Cor,quality control tools,calibration tools and auxiliary files
• End-to-end system performance monitoring – monitor performance of Sentinel-2 system operations(including the instrument)and assess the system
