Dans cet article, nous présentons des schémas de positionnement hybrides qui combinent les mesures de l'heure d'arrivée (TOA) et de l'angle d'arrivée (AOA) à partir de seulement deux stations de base (BS) pour localiser la station mobile (MS) hors ligne de visée (NLOS). ) environnements. Les méthodes proposées utilisent deux cercles TOA et deux lignes AOA pour trouver toutes les intersections possibles afin de localiser le MS sans nécessiter a priori informations sur l’erreur NLOS. L'algorithme de série de Taylor (TSA) communément connu et l'algorithme de lignes de position hybrides (HLOP) présentent des problèmes de convergence, et le positionnement relatif entre la MS et la BS affecte grandement la précision de la localisation. La géométrie résultante crée une situation dans laquelle de petites erreurs de mesure peuvent conduire à des erreurs significatives dans l'emplacement estimé du MS. Les résultats de simulation montrent que les méthodes proposées fonctionnent toujours mieux que TSA et HLOP pour différents niveaux d'erreurs NLOS, en particulier lorsque les MS/BS ont une disposition géométrique indésirable.

Abstract: In this paper we present hybrid positioning schemes that combine time of arrival (TOA) and angle of arrival (AOA) measurements from only two base stations (BSs) to locate the mobile station (MS) in non-line-of-sight (NLOS) environments. The proposed methods utilize two TOA circles and two AOA lines to find all the possible intersections to locate the MS without requiring a priori information about the NLOS error. The commonly known Taylor series algorithm (TSA) and the hybrid lines of position algorithm (HLOP) have convergence problems, and the relative positioning between the MS and the BSs greatly affects the location accuracy. The resulting geometry creates a situation where small measurement errors can lead to significant errors in the estimated MS location. Simulation results show that the proposed methods always perform better than TSA and HLOP for different levels of NLOS errors, particularly when the MS/BSs have an undesirable geometric layout.
