Title
(EN) NAVIGATION DEVICE HAVING DEAD RECKONING NAVIGATION FUNCTIONALITY AND METHOD THEREOF
(FR) DISPOSITIF DE NAVIGATION AYANT UNE FONCTIONNALITÉ DE NAVIGATION PAR POINT ESTIMÉ ET PROCÉDÉ POUR CELUI-CI
Abstract
(EN)
Embodiments of the present invention provide a method of determining a heading of travel of navigation device (200), comprising determining a reference heading for a roadway system and determining a current heading of navigation device (200) travel, wherein the current heading is determined as an integer multiple of a predetermined lock angle in combination with the reference heading.
(FR)
Des modes de réalisation de la présente invention portent sur un procédé de détermination d'un cap de déplacement d'un dispositif de navigation (200), comprenant la détermination d'un cap de référence pour un système routier et la détermination d'un cap actuel d'un déplacement du dispositif de navigation (200), le cap actuel étant déterminé en tant qu'un nombre entier multiple d'un angle de verrouillage prédéterminé, en combinaison avec le cap de référence.
