MTG Ground Segment Context MTG GS Major Components: • Ground Stations Facilities (TTCF, Ground Stations Dissemination MDAF) • Mission Operation Facility (MOF) • Data Processing Facilities (IDPF, L2PF) • Multi-Mission Elements (MMEs) Note: “Facility” = hardware + software Mission Operation Data Processing Archive and Retrieval EUMETSAT Headquarter SAF Network EUM/MTG/VWG/13/715994 Slide: 25 July 2013 4

Instrument Data Processing Facility (IDPF) The IDPF receives raw instrument data and performs: Science data extraction and chunking (for parallel processing); • Radiometric and spectral calibration; • Geometric rectification to a reference grid (FCI only); • Image Navigation and Registration; • Aggregation of chunks and formatting into output file. • It provides also capabilities for Algorithm Development, • Fast Scientific Validation and Reprocessing (at least 5 times faster than near-real-time processing). EUM/MTG/VWG/13/715994 Slide: 25 July 2013 7

Level 2 Processing Facility (L2PF) The L2PF generates meteorological products from the Level-1 data • produced by the IDPF . Flexibility and simplicity to include new products are key features of • EUMETSAT level 2 processing Contract(s) will foresee the capability to add in additional products, • potentially developed in house by EUMETSAT (including products developed by Satellite Application Facilities) Flexibility is also considered for the evolutions of existing products • during the development of the L2 Facility It provides also capabilities for Algorithm Development, • Fast Scientific Validation and Reprocessing.

Multi Mission Elements (MMEs) What are the Multi-Mission Elements ? Elements currently used in several Operational Programmes or evolution of them, and can be re-used for future • programmes, in particular for the MTG Ground Segment. These are identified as Multi-Mission Elements (MME) • The main reasons for considering re-use are: Reduced development risks and costs • Reduce long-term maintenance costs • Consistency towards end users • Easier, homogeneous operations • EUM/MTG/VWG/13/715994 25 July 2013

The MMEs provide the following functions for MTG Data Archive (MME DAC) § long term archival and retrieval of MTG mission data • user support and helpdesk services, including service registration • Dissemination (MME DIS) § dissemination of data to end users via EUMETCast, RMDCN/GTS and Internet • presentation of data via Internet (rolling archive, image generation) • ingestion of data from external parties into the GS • master and session keys for TC authentication and payload data encryption • Monitoring (MME MON) § analysis and reporting (including science and long term trend analysis) • centralised monitoring capabilities for the whole MTG ground segment • end-to-end production, service status, hardware, remote spacecraft telemetry • Infrastructure (MME INF) § network connectivity to/from the MMEs and inter-building • internet, RMDCN/GTS lines and network security • time reference, voice loop and data protection services • EUM/MTG/VWG/13/715994 Slide: 10 25 July 2013

Ground Segment Technical Challenges EUM/MTG/VWG/13/715994 Slide: 25 July 2013 11

MTG Operational Availability datasets received and that meet the quality thresholds datasets scheduled to have been sent or made *For a given period and removing the part corresponding to the scheduled outages and the available external outages Major contributing components of the Ground Segment Operational Availability are: Completeness; Accuracy; Timeliness Note: As opposed to Space Segment, any Ground Segment outage, planned or unplanned, • contributes negatively to the operational availability; Any systematic loss of quality introduced due to data formatting or compression in • order to comply with the agreed format specifications does not contribute to operational availability of the ground segment.

MTG Timeliness Time difference The end of reception The foreseen end of of the corresponding acquisition of the last data by the users contributing data *before decryption and *from a sample, a dwell, decompression a swath, a granule It excludes: delay introduced by transmission lines and networks outside EUMETSAT control • ( e.g. Internet, GTS). the processing time outside EUMETSAT control ( e.g. SAF processing time). • EUM/MTG/VWG/13/715994 Slide: 25 July 2013 13
