La navigation précise des piétons reste un défi en milieu urbain. Le récepteur GNSS se comporte mal en raison de la réflexion et du blocage des signaux GNSS par les bâtiments ou autres obstacles. L’intégration du positionnement GNSS et du Pedestrian Dead Reckoning (PDR) pourrait fournir une trajectoire de navigation plus fluide. Cependant, le système d'intégration ne peut pas présenter les performances satisfaisantes si le positionnement GNSS présente une erreur importante. Cette situation se produit souvent dans le scénario urbain. Cet article se concentre sur l’amélioration de la précision de la navigation piétonne en environnement urbain à l’aide d’une méthode de positionnement GNSS assistée par carte d’altitude. Premièrement, nous utilisons un algorithme de contrôle de cohérence, similaire à la détection des défauts de surveillance autonome de l'intégrité du récepteur (RAIM), pour distinguer les mesures saines et contaminées par trajets multiples. Les signaux erronés sont ensuite corrigés à l'aide d'une carte d'altitude. Nous avons appelé la méthode proposée la carte d'altitude assistée par GNSS. Après avoir corrigé les signaux satellite erronés, l'erreur moyenne de positionnement a pu être réduite de 17 mètres à 12 mètres. Habituellement, de bonnes performances pour le système d’intégration nécessitent une valeur de précision GNSS calculée avec précision. Cependant, le calcul conventionnel de la précision du GNSS n’est pas fiable dans les canyons urbains. Dans cet article, la carte d'altitude est également utilisée pour calculer la précision de la localisation GNSS afin d'indiquer la fiabilité de la solution de position estimée. La carte d'altitude assistée par GNSS et la précision sont utilisées dans l'intégration avec le système PDR afin de fournir des résultats de positionnement plus précis et continus. Grâce à la précision GNSS proposée, le système d'intégration pourrait atteindre une précision de positionnement horizontal de 6.5 mètres en environnement urbain.

Abstract: Accurate pedestrian navigation remains a challenge in urban environments. GNSS receiver behaves poorly because the reflection and blockage of the GNSS signals by buildings or other obstacles. Integration of GNSS positioning and Pedestrian Dead Reckoning (PDR) could provide a more smooth navigation trajectory. However, the integration system cannot present the satisfied performance if GNSS positioning has large error. This situation often happens in the urban scenario. This paper focuses on improving the accuracy of the pedestrian navigation in urban environment using a proposed altitude map aided GNSS positioning method. Firstly, we use consistency check algorithm, which is similar to receiver autonomous integrity monitoring (RAIM) fault detection, to distinguish healthy and multipath contaminated measurements. Afterwards, the erroneous signals are corrected with the help of an altitude map. We called the proposed method altitude map aided GNSS. After correcting the erroneous satellite signals, the positioning mean error could be reduced from 17 meters to 12 meters. Usually, good performance for integration system needs accurately calculated GNSS accuracy value. However, the conventional GNSS accuracy calculation is not reliable in urban canyon. In this paper, the altitude map is also utilized to calculate the GNSS localization accuracy in order to indicate the reliability of the estimated position solution. The altitude map aided GNSS and accuracy are used in the integration with PDR system in order to provide more accurate and continuous positioning results. With the help of the proposed GNSS accuracy, the integration system could achieve 6.5 meters horizontal positioning accuracy in urban environment.
