基于北斗+5G的室内外融合定位方法研究

his article proposes a joint Beidou+5G indoor and outdoor positioning system to address the problem of single satellite navigation positioning being difficult to meet the requirements of indoor and outdoor full scene positioning in complex indoor and outdoor scenarios. The method proposed in this article adopts Beidou positioning in outdoor open areas; Utilize 5G assisted Beidou positioning in outdoor shaded areas; Utilize 5G positioning in indoor areas. And conduct actual testing experiments at a driving school in Zengcheng District, Guangzhou. The experimental results show that the entire indoor and outdoor fusion positioning system has relatively ideal positioning accuracy. In outdoor areas, the proportion of positioning errors within 2cm reaches 91.09%.At point A1 indoors, the positioning error is around 16.31cm; Indoor A2 point, positioning error is around 15.54cm.
