An opportunity for an experienced engineer to provide support on site at ESTEC to the Earth Observation Future Missions Division (D/EOP-SF) with the development of end-to-end simulators and System Engineering Tools and to support Mission Performance and System Engineering activities
The Future Missions Division at ESTEC is tasked with preparing new EO missions and technologies. To support this work a contractor is required to work with the definition, development and exploitation of end-to-end simulators for future EO missions, aiming at a coherent and representative modelling of each element of the system (satellite, payload, ground processing) contributing to the end-to-end mission performance, and maximising the synergies and reuse of building blocks from one simulator to the next. Further support will be required in the definition, development and exploitation of System Engineering Tools for future EO missions.
Responsibilities / Duties
Duties will include but are not limited to the following two areas:
Area 1 – End-to-End Simulations for future EO missions:
- Support the definition and development of the End-to-End (E2E) Mission Performance Simulators for future EO missions, including elaboration of SOW and technical specifications, participation to progress meetings and reviews.
- Contributing to ensure the technical coherency and completeness of the simulation of the observation system, including, as needed, functional analysis, system level budgeting, system performance analyses, modelling of spacecraft and/or payload subsystems and related data processing to meet system and mission requirements.
- Install and use those E2E simulators on the EOP-SF IT infrastructure for mission performance evaluation and system trade-offs for future EO missions.
- Provide feedback from end-to-end mission performance simulations and optimisations to the spacecraft and mission design.
- Ensure a consistent evolution and maintenance of the E2E simulators and a proper configuration and storage of the relevant input/output data sets.
- Initiate and support work in the area of modelling of system or sub-system aspects (spacecraft, payload, ground processing) for E2E simulators and System Engineering Tools.
- Support the development of generic building blocks and modules, and aim at maximum synergy and reuse of those building blocks and modules from one E2E simulator to the next making use of ESA OpenSF infrastructure.
Area 2 – System Engineering Tools for future EO missions:
- Participate to the development of new System Engineering Tools for preliminary analysis and sizing of future EO missions, ensuring a coherent and representative modelling of each element of the system (satellite/platform and its subsystems, payload, ground processing) contributing to the system performance.
- Participate to the evolution and maintenance of the existing System Engineering Tools used in EOP-SF.
- Use the above System Engineering Tools for system trade-offs, preliminary sizing and performance evaluation of future EO missions.
- Provide feedback from mission optimisation to the spacecraft and mission design.
Qualifications / Experience
- University degree (MSc minimum) or equivalent in Aerospace Engineering or another relevant engineering discipline.
- At least 4 years relevant industrial experience with a background in space system engineering and General knowledge of ESA Earth Observation missions.
- Background in space system engineering.
- Experience in mission analysis.
- Solid background on IT and computer programming including MATLAB, Python, STK, MS Excel and CAD software knowledge is an asset.
- Experience on modelling and simulation of observing system characteristics (spacecraft, payload, ground processing, orbit…) and how they impact mission data quality and relate to system requirements and scientific goals is desirable.
- Versatility to adapt to the specificities of each mission considering the wide range of possible EO observation techniques (e.g. optical/microwave, passive/active, imager/sounder, nadir/limb observation…) and platforms (e.g. mini/micro/nanosatellite), orbits (Sun-Synchronous or drifting, LEO/MEO/GEO/HEO).
- Experience with system performance simulation is an asset.
- Knowledge on optimisation techniques is an asset.
- Good English language skills
- Excellent interpersonal skills, a proactive approach, with initiative and capability to work independently.
- Problem-solving oriented attitude.
- Good organizational, communication and technical writing skills, with the ability to work in a diverse team environment.
- Capability to coordinate a large amount of inputs, synthesise, summarise and take
All roles within Telespazio VEGA have a defined closing date, however if a successful candidate is found before the advert expires the role will be closed early. We would therefore advise any candidate to apply as early as possible to avoid disappointment.
Location of the position is ESTEC, Noordwijk, The Netherlands
