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 ...
This is a presentation of the techniques used to process inertial and GPS data collected during an airborne gravimetric and altimetric survey in order to obtain absolute position and attitude estimates of the sensors mounted on board the aircraft. For high ...
In this paper we consider the problem of node positioning in ad-hoc networks. We propose a distributed, infrastructure-free positioning algorithm that does not rely on Global Positioning System (GPS). The algorithm uses the distances between the nodes to b ...
A special cryogenic press has been built to study the mechanical and electrical propel-ties of full-size ITER multistrand Nb3Sn cable-in-conduit conductor samples under transverse, mechanical loading. This simulates the transverse magnetic force that occur ...
The determination of instantaneous positions with high accuracy using differential GPS techniques is of great importance for several applications, like airborne topographic mapping, airborne gravimetry and altimetry. In some of these applications long base ...
Supercapacitors are new and powerful components for energy storage. Compared with batteries, the amount of energy they can store is low. But, as power sources they have the property to be re-loadable in a few seconds [1][2][3]. In that case, the needed ins ...
Le projet de recherche Evaluation des systèmes existants pour le suivi à long terme des déformations des ponts a été initié dans le but de préparer sous forme condensée une présentation et une évaluation des systèmes de mesure existants pour le suivi à lon ...
