[Introduction]：Le module de positionnement et de navigation unique Beidou E108-GN03BD est un module de positionnement et de navigation hautes performances basé sur la puce unique Beidou SOC de sixième génération AT6668B de Zhongkewei. Il utilise la nouvelle technologie de navigation intégrée SOC à puce unique, qui peut répondre aux applications de positionnement de haute précision et de synchronisation de haute précision. Il présente les caractéristiques d'une intégration élevée, de hautes performances, d'une faible consommation d'énergie et d'une petite taille. Il prend également en charge les signaux Beidou-2 (B1I) et Beidou-3 (B1C). Cette série de modules comprend trois packages communs et est compatible avec les interfaces logicielles et matérielles des modules GNSS d'autres fabricants. Il peut être utilisé dans des domaines d'application tels que la navigation embarquée, les appareils portables, les téléphones mobiles, les appareils IoT et les drones.
