TOULOUSE

En résumé

After studies focused on electronic, signal processing and control, I ended with a Ph.D. in 1987 mainly dedicated to the automation of a polymer characterization facility by dielectric spectroscopy. Much of the work, not published to protect the invention, were about adaptive and self-tuning control.

After an attempted start-up, I started in the Aerospace & Defense Space Company (at Les Mureaux) in May 1989, first as a business engineer for the Functional Ariane 5 Simulation Facility, then for nearly seven years as a technical manager of the control algorithm and the GNC integration of the Ariane 5.

In March 1996, I transferred to the Cannes industrial site dedicated to satellites as a project engineer for thermal vacuum tests. For fifteen years, I have participated to satellites testing with, as a main task, solve problems upstream (thermocouple thermometry, measurement details, resolution recurring faults, etc.) Meanwhile, I developed identification algorithms, some for the CoG determination from inertia measurements on Schenck table.

In 2010, the test center reorganization allowed me to focus my activities on the signal processing. Therefore, several developments are emerging, particularly a simulator of satelite vibration test leading to communications: it currently continues to evolve and allows Thales Alenia Space to predict the test abort from a low level throughput. As my different expertise is therefore recognized internally as some of our competitors, I transferred the Expertise Department in 2013.

I am now waiting for a recognition of "Expert Thales Simulation and control of Testing" but it requires a IIIB position (excluding premium pay > 58 k€) when I am just a IIIA position since 1992 ( premium pay off about 46k€).
