is at the head of the Laboratory of Electronics and Physics, at SUPAERO. His work includes the research, for applications in Digital communications and Signal processing, of solutions with DSP processors and Programmable logic devices or ASICs. He has experience in GNSS receivers design. He is currently working on new Galileo signal processing and GNSS receivers architecture. He is involved in several projects devoted to positionning and attitude determination, including low cost MEMS sensors characterisation and INS/GPS integration. He received a Ph.D, in Signal Processing, from SUPAERO (ENSAE, TOULOUSE, FRANCE).
Lecture: GNSS/INS Sensor Fusion
This lecture focuses on navigation systems based on GNSS receiver and Inertial sensors. First GNSS receiver is analyzed. Special care is taken to provide understanding of GNSS based positioning. In pursuit the optimal Kalman filtering is introduced and an example is proposed to illustrate this technique and to show some limitations when a receiver is used as a stand-alone navigation system. Then Inertial systems are studied and a INS navigation system is designed. Its performance depends on the technology. Gyroscope and Accelerometer models are proposed to explain Stand-alone INS performance. GNSS and INS systems have complementary characteristics. Different approaches, based on Kalman filtering, are proposed to design an integrated GNSS/INS system. Further some results are presented and finally some improvements are proposed.
