Title
(EN) TECHNOLOGIES FOR VEHICLE POSITIONING
(FR) TECHNOLOGIES DE POSITIONNEMENT DE VÉHICULE
Abstract
(EN)
Various vehicle technologies for improving positioning accuracy despite various factors that affect signals from navigation satellites. Such positioning accuracy is increased via determining an offset and communicating the offset in various ways or via sharing of raw positioning data between a plurality of devices, where at least one knows its location sufficiently accurately, for use in differential algorithms.
(FR)
L'invention concerne diverses technologies de véhicule pour améliorer la précision de positionnement en dépit de divers facteurs qui affectent des signaux provenant de satellites de navigation. Une telle précision de positionnement est augmentée par la détermination d'un décalage et la communication du décalage de diverses manières ou par le partage de données de positionnement brutes entre une pluralité de dispositifs, au moins l'un connaissant son emplacement de manière suffisamment précise, pour une utilisation dans des algorithmes différentiels.
