You will have the opportunity to provide support to the Ground System Definition & Verification Office at the European Space Agency.

Tasks and Activities
  • Monitoring the development of the Level 2 Software developed through a contract.
  • Ensuring the integrity of the Level 1B and 2 ground prototype processors and its algorithms to meet the necessary functionality and performances, taking into account system, instrument, geophysical model and calibration/validation facility aspects and the Ground segment PDS interfaces constraints.
  • Ensuring the integrity of the L1B and L2 performance simulators developed through a contract, and maintaining an up to date operating copy at ESTEC.
  • Preparing and maintaining performance budgets and analysing impacts on the Swarm mission performances resulting from deviations during the development programme.
  • Ensuring the proper verification and validation methods are proposed and implemented.
  • Support the preparation of agreements with potential calibration facilities.
  • Support campaign and the analysis of the data collected.
  • Identifying and resolving problem areas.
  • Providing necessary inputs for the scientific meetings.
  • The assessment of the delivered scientific processing algorithm in Python.
  • The assessment of the delivered Instrument Quality Tool IQT v2-alpha and its ability to process real instrument data (PFM Focal Plane SubSystem data, S4 enhanced EM data, …).
  • The assessment of the delivered Level-1 Reference Processor and perform a comparison of the results with the IQT.
  • The development, implementation and validation of (complex) key data generation tools for the instrument calibration and performance verification tasks, as defined in the S4 on-ground calibration plan and in the L1b processing specification;
  • The support to the closed-loop testing between the S4/UVN measurement data, the IQT v2 and the calibration keydata to demonstrate adequacy, completeness and accuracy of the level-0 to level-1b data processing algorithms and the calibration keydata.
  • The contribution to meetings within ESA, industry and EUMETSAT.
