北斗+5G综合时空网赋能低空经济:技术架构、应用实践与未来展望
Empowering low-altitude economy with BDS/5G integrated spatiotemporal network:Technical architecture,application practice and future prospect
摘要
Abstract
As a new pillar of China's economic growth,the booming low-altitude economy hinges on core enabling technologies including positioning,navigation and wireless communication.The Beidou-5G integrated spatiotemporal network,a novel infrastructure combining the Beidou Navigation Satellite System(BDS)and 5G,delivers integrated communication and navigation services essential to low-altitude operations and fuels sound development of the low-altitude economy.Centered on this network and taking Beidou-5G integrated base stations as core nodes,this paper systematically investigates low-altitude UAV communication-navigation integration basics.It compares native BDS and 5G features,exposes drawbacks of standalone deployment,and presents the network's overall framework.Key dis-cussions cover integrated base station hardware,5G control-plane broadcast technology and network layout schemes.Benchmarking rival base station designs proves 5G control-plane broadcast excels in low latency,massive concurrency and robust security.This paper assesses the network's support for low-altitude scenarios from five perspectives:full-coverage high-precision time synchronization,centimeter-level positioning improvement,multi-aircraft collaborative sensing,low-altitude weather and interference surveillance,and upgraded communication performance.It further dis-cusses integration and construction hurdles,then forecasts trends such as communication-sensing-navigation fusion,advanced Positioning,Navigation and Timing(PNT)services and innovative network operation modes.The final conclu-sion:large-scale rollout of Beidou-5G integrated base stations fixes key low-altitude bottlenecks-unreliable positioning,weak airspace oversight and safety risks-by establishing a converged digital spatiotemporal platform.This research of-fers valuable guidance for technical tuning and industrial rollout of the low-altitude economy.关键词
