[Introduction]：Le module Beidou simple de la série EWM108-GN06B est basé sur la puce multifréquence simple Beidou AT9880B de nouvelle génération de Zhongkewei. Il prend en charge les signaux de fréquence B1I, B1C, B2I, B3I, B2a et B2b des systèmes Beidou-2 et Beidou-3. Grâce à l'intégration d'un processeur embarqué hautes performances, la fréquence de mise à jour du positionnement peut atteindre 10 Hz.
