2015-02-18 13:05:23| Space-careers.com Jobs RSS
With 1.700 employees worldwide, the CS Group is a leading IT company in France and in Germany, and a prime contractor in designing, integrating and operating mission critical systems. It has now been over 30 years that comprehensive CS solutions for space systems and applications, both on the ground and in space, have been part and parcel of this odyssey. Our German activities grow at fast pace and to face our costumers high level expectations and needs, we are looking for talented profiles having relevant experience in Space systems and applications. EPSSG will be based on a twosatellites configuration with respectively launch of the first satellite MetopSG A mid 2021 followed by the second satellite MetopSG B 18 months later. Two recurrent Metop SG A and B satellites will be provided and launched in order to achieve a minimum of 21 years of operations. Regarding the Space Segment, EUMETSAT will rely on cooperation with ESA for the development of the satellite and of a subset of the instruments. EUMETSAT will cooperate with other Partners for the acquisition of the other instruments including the METimage DLR, IASING CNES and ARGOS4 CNES. Regarding the Ground Segment, EUMETSAT will develop and procure its Ground Segment capitalising on existing Multi Mission Elements that are already in operation in the Headquarters as well as on the Satellite Application Facilities SAF Network, taking into account the lessons learnt from previous programmes. EPSSG will be the second generation of EUMETSATs polar system and as such will have a strong heritage from the existing EPS with its Metop satellites and operations, and from other elements of the EUMETSAT infrastructure in support of current programmes. TASKS The activities for the selected keyperson will be related to overall System aspects for endtoend instrument functional chains, i.e. involving the space segment satellites as well as the ground segment, the latter consisting of the data acquisition systems, monitoring and control systems, data processing chains and product dissemination facilities. In the frame of endtoend instrument chain activities, the keyperson will be part of the EPSSG System team and provide support for tasks related to mission performance allocations and budgeting, definition and specification of scientific algorithms for geolocation, radiometric correction and spectral calibration, definition of the approach for instrument calibration and product validation, specification of enduser products for imaging and sounding instruments. It is emphasized that a major part of the work to be undertaken by the engineer will be to follow up and assess the outcome of the ongoing activities done by different groups in the EPSSG team EPSSG system team, EPSSG instrument team, EPSSG science team and EPSSG ground segment team, and ensure that all the inter disciplinary activities are done in a systematic way, compatible with the EPSSG programme objectives and constraints. The activities to be followed up are in the following areas Development of the algorithms specifications Algorithms Theoretical Baseline Document ATBD, Detailed Processing Model DPM and processing specifications Product Generation Specifications PGSs, Product Format Specifications PFSs and Auxiliary Data Specifications ADS Development of reference processors that implement the functionalities defined in the processing and algorithms specifications, including verification of the EndtoEnd E2E performance requirements spectral, radiometric and geometric requirements Development of the operational processors with emphasis on the implementation of the processing algorithms and their compatibility with EndtoEnd E2E performance requirements spectral, radiometric and geometric requirements Preparation of Instrument CalibrationValidation plans, including the definition of the approach for validation of the Level 1 and Level 2 products and of any related algorithms Development of the calibration, validation and offline monitoring facilities EndtoEnd E2E performance requirement spectral, radiometric and geometric requirements allocation and budgeting performed by space segment and instrument providers, specifically when dealing with processing algorithms. Typical activities to be undertaken by the engineer are Contribute to the consolidation and maintenance of the system requirements relevant for the development of the EPSSG enduser products, including tracing to enduser requirements and tracking of the status of compliance any incompatibilities to the EPSSG System requirement baseline need to be identified and resolved Confirm that the operational processors which are developed as part of the EPSSG ground segment are able to meet the EPSSG E2E performance requirements spectral, radiometric and geometric requirements any inconsistencies and noncompliances need to be identified and resolved Support validation of products and verification of processing algorithms, specifically the cross comparison of products generated by the operational processors against output of reference processors Review and contribute to the preparation of algorithms specifications and product specifications to confirm and ensure their consistency with the System requirements and design documents Review space segment and instrument documents e.g. ATBD, DPM, Instrument Calibration and Characterization Specification to identify implications for the processing specifications of the operational processors. Assess implications ofcontributions by the processing algorithms to E2E performance requirements and contribute to the compilation and documentation of E2E performance budgets any noncompliance with the EPSSG System E2E performance requirements need to be identified and resolved review the adequacy of related tools for E2E performance modelling and, as needed, support development of complementary inhouse modelling tools Support regular reviews of System, Space Segment and Ground Segment documentation relevant for EPSSG data processing chains and E2E performance requirements spectral, radiometric and geometric requirements Participate in formal reviews and technical meetings at system and ground segment level Support preparation of documentation for System level reviews Support coordination of interdisciplinary meetings relevant for data processing chains Support studies internal or external and evaluate their results when relevant for data processing chains, including specification and validation of algorithms Consolidate the verification approach for System E2E performance requirements spectral, radiometric and geometric requirements and maintain the related verification matrix. Most activities will involve interactions with other teams, primarily in the LEO division, and also, as relevant for the work, with engineers at partner agencies. PROFILE The keyperson shall have the following experience and background University degree in the domain of engineering, science, or equivalent Direct involvement in the following areas, with at least 3 years of combined experience Specification of level 1 algorithms for geolocation, spectral and radiometric correction and calibration and of level 2 geophysical algorithms, for spaceborne observation systems as imaging andor sounding instruments Mission performance analysis, budgeting and verification for spaceborne observing systems as imaging andor sounding instruments. The following experience would be an additional asset Knowledge of relevant spaceborne observation instruments EPSSG satellites will embark sounders and imagers from the ultraviolet to the microwave range, a scatterometer and a radiooccultation instrument. The keyperson shall be able to fulfil the assigned tasks with a minimum of supervision, have a systematic approach to work, be able to plan hisher work and to cope with tight schedules and multiple tasks. Heshe shall have the capability to write accurate and consistent technical documentation. Good communication skills verbal and written are important. Heshe shall be willing to work in a team of engineers and in cooperation with industry and partner agencies. The official languages of EUMETSAT are English and French. The working language for the position is English and therefore the keyperson must be able to work effectively in this language. How to apply Please consider the following points before applying Please submit your complete application documents in English. An attached cover letter should mention your availability and salary expectations. Interested applicants should submit their CV to marina.ludwigcssystems.de with CC to francoisxavier.laffontcs.fr with the job title.
