ACS is looking for a consultant to support the EPSSG EUMETSAT Polar System Second Generation Programme at EUMETSAT. The focus of the work is on endtoend 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 keyperson would be involved in tasks such as mission performance allocations and budgeting, processing chain specification, approach for instrument calibration and product validation. ACS has more than 30 years experience in delivering solutions for Earth Observation satellites Ground Segments. Based in Rome, Italy and in Darmstadt, Germany, we delivered systems currently in operation in 20 countries worldwide and have a long record of successful projects carried out for ESA, EUMETSAT, EMSA and many other Space Agencies and Research Centres. ACS recently established German subsidiary ACSD aims at better serving our customers based in Darmstadt area. ACS offers pleasant, international working environment at customer site very competitive salary attractive benefit package tailored on specific exigencies training and personal growth within ACS group, full support from a high technology company for relocation to Darmstadt. The activities for the selected keyperson will be related to overall System aspects for endto end 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. 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 consultant 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. 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 o 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 o 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 working language for the position is English and therefore the keyperson must be able to work effectively in this language.
