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).

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

The MMEs provide the following functions for MTG

Slide: 10

§

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

MTG Operational Availability

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
  • rder to comply with the agreed format specifications does not contribute to
  • perational availability of the ground segment.

Slide: 12

datasets received and that meet the quality thresholds datasets scheduled to have been sent or made available

*For a given period and removing the part corresponding to the scheduled outages and the external outages

MTG Timeliness

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).

Slide: 13

Time difference The foreseen end of acquisition of the last contributing data

*from a sample, a dwell, a swath, a granule

The end of reception

  • f the corresponding

data by the users

*before decryption and decompression
