EGNOS (European Geostationary Navigation Overlay Service) sera le système d'augmentation satellitaire européen. Il améliorera la performance des deux systèmes satellitaires militaires GPS (Global Positioning System) et GLONASS (Global Navigation Satellite ...
We consider multiple antenna systems in which a large number of antennas occupy a given physical volume. In this regime the assumptions of the standard models of multiple antennas systems become questionable. We show that for such spatially dense multiple ...

In view of the operational validation of EGNOS, some early tests are being performed with the EGNOS System Test Bed (ESTB). This prototype has been broadcasting an EGNOS-like signal since early 2000. The performance of ESTB is reduced compared to the full ...
The challenge of knowing one's position in a precise and reliable way, at any time, with and without reception of satellite signals, represents an area fairly explored for the navigation of vehicles. To widen this service to the pedestrians requires a diff ...
This work was motivated by the increasing need for acoustic localization systems. The various localization systems that were implemented during this PhD include localization of snow avalanches, artillery and supersonic aircraft in the infrasound domain, th ...
Within the validation work of EGNOS for civil aviation, it is interesting to analyze the transmitted corrections individually. In this paper, the ionospheric model of EGNOS is compared to the one determined by an independent organization (CODE). The contin ...
The development of efficient systems for precise attitude and position determination of airborne sensor platforms is having a huge impact in different remote sensing applications, resulting in higher productivity levels and lower exploitation costs. This t ...
Downhill skiers enter a different dimension on the racecourse, but they are still subject to the laws of physics. A new Swiss system integrates GPS, video, and biosensors for precise position, velocity and heart-rate measurement, helping coaches and athlet ...
In this work we consider multiple antenna systems in which a large number of antennas occupy a given physical volume and we investigate the behavior of the capacity when increasing the number of antennas. In this regime the assumptions of the standard mult ...
