Abstract

Abstract

BeiDou Navigation Satellite System (BDS) provides high-precision positioning services globally, but faces challenges in urban canyons and indoor environments. However, with the widespread commercial adoption of 5G and advancements in sub-meter level positioning accuracy, integrating BeiDou with 5G can enable ubiquitous and seamless indoor and outdoor integrated positioning solutions, which holds significant implications for China’s implementation of its positioning, navigation and timing (PNT) strategy. This article summarizes the key principles and characteristics of wireless positioning technology, traces the evolution of mobile communication network positioning technology, and highlights the latest 5G positioning methods. It further categorizes BeiDou+5G fusion positioning into two levels: enhanced positioning and fusion positioning. Fusion positioning is further divided into weighted fusion positioning and signal fusion positioning based on the degree of coupling in the positioning process. Additionally, strategies for BeiDou+5G fusion positioning in different scenarios are presented. Finally, the article discusses the current development status and potential applications of BeiDou+5G fusion positioning, aiming to provide a valuable reference for further research and practical implementation of BeiDou+5G fusion positioning.
