The focus of the work is on end-to-end instrument chains, from acquisition of signals by instruments on board the satellites up to dissemination of derived products to End Users by the ground segment. The selected key-person would be involved in tasks such as mission performance allocations and budgeting, processing chain specification, approach for instrument calibration and product validation. The coordination with different teams involved in these activities plays a key role given the interdisciplinary nature of end-to-end instrument chains.
The key-person would be a member of the EPS-SG System Team in the Low Earth Orbit Division (LEO) at EUMETSAT.
The tasks of these positions include in particular:
•Identification of contributors to performances (radiometric / spectral / geometric); allocation / apportionment to elements of the instrument chains.
•Definition of approach for performance modelling; review of adequacy of related modelling tools.
•Compilation and analysis of end-to-end performance budgets, as needed collecting input from space and ground segment studies; cross check against applicable requirements.
•Definition of overall approach for the development, verification and validation (V&V) of the processing chains as part of the overall EPS-SG System.
•Identification of implications of processing concepts for System/ ground segment requirements, architecture and design.
•Identification of required tools and test data for the development and V&V of the processing chains; as relevant generation of technical documents to support tool development / procurement.
•Support for the development of relevant tools and the generation of required test data sets
•Following up of validation of processing algorithms and of verification of processing chains in the ground segment as relevant for System V&V of the end-to-end instrument chains.
Instrument calibration & product validation:
•Analysis of the implications of instrument calibration concepts for the System and ground segment and specifically for on-ground data processing.
•Support for the definition of the required infrastructure to perform tuning / maintenance of calibration data and to validate generated products. In addition the key-person will be involved in some more general tasks:
•Regular review of System level documentation dealing with requirements, system concepts, architecture and design, technical analyses, to identify information of importance for end-to-end instrument chains.
•In addition, and with the same aim, analysis of documents provided by other teams in EUMETSAT and by external partners.
•Support for coordination of interdisciplinary meetings of relevance for the instrument chains.
•Support for the preparation of documentation for System level reviews, during the covered period mainly the System Requirements Review and the Preliminary Design Review.
