AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
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 ...
Applications of global navigation satellite system (GNSS) in land transportation systems are already extensively deployed and will certainly continue to grow especially in the framework of intelligent transport systems. However, one of the best-known drawb ...

In this paper, a software tool for the prediction of the corona discharge and the multipactor thresholds in passive components based on rectangular geometry for space applications is presented.The software tool has been compare to measurements showing a ve ...
When satellite signals are available, the localisation of a pedestrian is fairly straightforward. However, in cities or indoors, dead reckoning systems are necessary. ...

When satellite are available, the localisation of a pedestrian is fairly straightforward. However in cities or indoors, dead reckoning systems are necessary to determine the user's position. Our current research focuses on the development of algorithms and ...
This paper presents the final results of the performances of the High resolution Standard Proximity Sensor developed under a GSTP contract for ESA /ESTEC. The HRSPS is a general purpose displacement measuring system developed with the aim to replace the mu ...
Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...
The structure of a crystal of Sr0.61Ba0.39Nb2O6 has been solved and refined as an incommensurate structure in five-dimensional superspace. The structure is tetragonal, superspace group P4bm(pp1/2; p-p1/2), unit-cell parameters a = 12.4566 (9), c = 7.8698 ( ...
