摘要: 卫星导航在国防和国民经济领域占据了越来越重要的地位,其所提供的定位、导航和授时等服务已经逐渐为人们熟悉并依赖。卫星导航定位解决了室外空旷区域定位的基本需求问题,在室外空旷区域北斗系统已经能够提供较为可靠的定位结果,但卫星信号无法覆盖室内,难以满足必要的定位条件。5G 系统具有密集组网、大带宽和多天线等对定位有利的条件,通过北斗与5G 的深度融合,可构建室内外无缝定位体系,满足日益增长的泛在定位需求。分析了北斗+5G 融合定位的发展现状,介绍了几种典型的融合定位技术,最后通过仿真对融合定位技术的性能进行了验证。

Abstract: Satellite navigation plays an increasingly important role in the field of national defense and national economy,and people have been gradually familiar and relied on its positioning, navigation and timing service. Satellite navigation and positioning system has covered the basic requirements of positioning in outdoor areas. In outdoor open areas, the Beidou system has been able to provide relatively reliable positioning performance, but the satellite signals cannot cover indoor areas, so it is difficult to meet the necessary positioning conditions. 5G system has several favorable conditions for positioning e. g. , dense network, large bandwidth and multiple antennas, etc. Through the integration of Beidou and 5G, a seamless indoor and outdoor positioning system can be built to meet the growing demand for ubiquitous positioning. This paper analyzes the development of Beidou and 5G integration positioning systen, introduces several typical integration positioning technologies, and finally verifies the performance of the integration positioning technology through simulation
