63 2.2 Hybridation: Fusion Algorithms WiFi + INS

64 2.2 Hybridation: Fusion Algorithms GPS+ SIG Urban areas are known as difficult environments for GPS based positioning : deep streets mask GPS signals or create multipath effects that result in degraded accuracy or lacks of coverage. Traditional map matching is not suitable for pedestrian usage, and sometimes fails for cars.

65 2.2 Hybridation: Fusion Algorithms GPS+ GSM Positioning error vs time for scenario 2 with 7 GSM BTS in sight and 0 satellite available between t=51 and t=106 s Improved Positioning using GSM and GNSS Tight Hybridization P. Paimblanc,, W. Chauvet,, D. Bonacci, T. Sadiki, F. Castanié,, TESA Laboratory.

66 Conclusion For Safe Positioning in critical applications, absolutely necessary to «merge» (i.e carry out «Hybridation», or «Mitigation» actually «Data Fusion») of a wide variety of positioning means and measures. Many open questions, and consequently many research topics in Signal Processing, Data Fusion, Sensors
