  • Software engineer within the project "SX5 - Scientific Service Support based on Galileo E5 Receivers" funded by the European Union (EU) ⇒ single frequency positioning and ionosphere monitoring applications based on the Galileo E5 AltBOC signal
  • Project manager within the project "Growing NAVIS" funded by the European Union (EU) ⇒ education, training and research transfer for ASEAN countries
  • Project manager and software engineer within the project "Advantages of C-band and L-band atmospheric remote sensing" funded by the European Space Agancey (ESA) ⇒ benefits of a Galileo C-band signal for atmosphere monitoring using attenuation- and ground based methods and radio occultation techniques
  • Project manager and software engineer within the project "COSMEMOS" funded by the European Union (EU) ⇒ assessment of  the scientific benefits of implementing cooperative meteo-marine data collection schemas, coupled with innovative on board sensor architectures based on current and future GNSS receivers and ad-hoc data processing / fusion techniques.
