Real time engineer
Acting as computing project manager before and during the Corot mission, Philippe is in charge of a team of 5 engineers which are under contract to the CNES/INSU for 3 years. These engineers come from IUP (Professional University Institute), hold a DESS, and have at least 2 years of professional experience.
Philippe was trained in an IUP for industrial computing. Then he passed the DEA (French equivalent to a masters) in the same field, and obtained an engineering degree by taking CNAM evening classes.
Tasks for the CoRoT mission
The computing on the MI concerns the preparation of the mission : Philippe defines software to test
the commands for all the modules of the case, the DPU (Data Processing Unit), the acquisition line, the control of the camera, and the constraint box (temperature, photoelectric stability, synchronization), ...
The computing on the MV deals with the mission itself : Philippe designs the on board software. He also defines the specification, and the follow-up and the validation of flight software (tests and acceptance procedures). He develops software in collaboration with partner laboratories.
" I appreciate the numerous collaborations, for instance I work with a laboratory in Berlin on the flight software, and with a lab in Vienna on the definition of the extractor module, and the positioning software for the satellite, etc.
Software project manager of the Ground Segment, Sylviane, prepares the software necessary for the reception on Earth of the data transmitted by Corot during the mission. This data must be shaped and recorded in databases, before being used by the community. The Corot team in LESIA defines this data processing. 10 to 12 continuous observation runs of several months will be done during the Corot mission (which last between 2,5 and 3 years).
After two years of preparatory classes in physics and chemistry, Sylviane passed a "maîtrise" in signal processing. She worked 5 years as an engineer at Thomson, and passed a CNRS competitive examination to become an engineer in space data processing. Actually, she worked 12 years as head of the computer system for the LESIA laboratory. Then, she was promoted to research engineer (IR). Finally she became the person in charge of the Corot data analysis, in the Ground Segment.
Tasks for the CoRoT mission
Sylviane is in charge of the computer databases and the calibrations. She is the person in charge of the technical coordination of the activity of the laboratories in the Ground Segment : these laboratories carry out the definition and the specifications of programs (data analysis, databases).
She leads a team of developers in LESIA, and carries out the interface between the CNES (project manager) and the industrial subcontractors which make the software at CNES (Toulouse).
She is in charge of the software quality, the tests, etc.
She participates in computer policy at the laboratory and ensures that they are up to date with technological innovations.
"In this job, I collaborate with the quality engineers at LESIA and CNES. Contrary to spacecrafts that need several months or years to hit the target, Corot will start straight away to transfer data. Therefore, the data analysis software must be ready before the satellite's launch. The first data processing will be performed by the CNES (withdrawal of instrumental effects).
The software must be submitted to precise tests, and acceptance will be done before and during the flight. We must take into account every particular event that could happen, think about extreme conditions, etc..."
