Title (EN) MULTIPLE DATA SOURCES PEDESTRIAN NAVIGATION SYSTEM
(FR) SYSTÈME DE NAVIGATION DE PIÉTON À SOURCES DE DONNÉES MULTIPLES
Abstract: front page image
(EN)A method of pedestrian navigation, based on an external positioning system and a Dead Reckoning (DR) system is provided herein. The method may employ the following steps: obtaining external positioning readings from an external positioning source and DR position readings from a pedestrian-carried platform; estimating an external positioning error, based at least partially on the external positioning and the DR position readings; and applying an estimation function to the external position readings, the DR position readings, and the external positioning errors, to yield a corrected estimated position.
(FR)L'invention porte sur un procédé de navigation de piéton, basé sur un système de positionnement externe et un système de navigation à l'estime (DR). Le procédé peut employer les étapes suivantes : l'obtention de lectures de positionnement externe à partir d'une source de positionnement externe et de lectures de position DR à partir d'une plateforme portée par un piéton ; estimation d'une erreur de positionnement externe, sur la base, au moins en partie, des lectures de positionnement externe et des lectures de position DR ; et l'application d'une fonction d'estimation aux lectures de position externe, aux lectures de position DR et aux erreurs de positionnement externe, pour produire une position estimée corrigée.
