INDOOR NAVIGATION PERFORMANCE ANALYSIS 1. Context of indoor navigation The objective of this research is to define and to implement a dedicated data model for indoor applications. Based on this specific model, route guidance and navigation algorithms ca ...
Context of indoor navigation The objective of this research is to define and to implement a dedicated data model for indoor applications. Based on this specific model, route guidance and navigation algorithms can be integrated in order to develop applic ...
In this paper the perturbation influence properties of the stochastic model (variance-covariance) in linear models is discussed in detail. Some very useful formulae are established about the variance-covariance perturbation influence on the model parameter ...
La monétarisation de la mobilité est un thème qui préoccupe un grand nombre d'acteurs du domaine routier. Quels concepts et quelles technologies ? Comment les faire accepter ? Nombre de questions restent à résoudre. Et que peut apporter la navigation par s ...
La navigation pédestre est un domaine prometteur qui s'inscrit dans un contexte global de mobilité, en particulier dans les villes. D'est un grand défi de s'inspirer et d'adapter les concepts de la navigation automobile au contexte de la navigation pédestr ...
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 ...
Navigation is usually associated with marine and aviation domains. Except for some lighthouses for orientation or landmarks near the coast, navigation instruments are essential because routes are virtual. Therefore, current position of ships and aircrafts ...
Navigation systems are becoing standard in-vehicle equipment. In the future these technologies will take place in new systems called Intelligent Integrated Road Safety Systems. Reaching this high level of integration and these requirements needs more preci ...
The Geodetic Engineering Laboratory at EPFL has designed a mobile mapping system to determine the geometry of the road: the Photobus. This paper describes major steps that move the Photobus towards a real-time mapping system. ...
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 ...
