I am Filali Sadik Oumaima, i have obtained my diploma from ENAC as an engineer in space aeronautical telecommunications in 2020. In the same year and in the same university, I got my master’s degree too in aerospace systems, navigation and telecommunication. In 2019, I did a 4 months internship in “Parthenope” university of Naples. In fact, I've worked on the least median squares as a robust estimator for GNSS positioning. For my final study project, I joined M3systems in February 2020 to work on the integrity of GPS and EGNOS systems positioning with the extended Kalman Filter. I am currently an R&D engineer in the same company where I work on different projects related to GNSS signal processing.
