新一代通信导航一体化技术的进展研究

Research on the Progress of New Generation Communication and Navigation Integration Technology

近年来,在市场需求的促进下,卫星导航进入高速发展阶段,但其在室内场景中的覆盖性能较差,因而需要进行优化。通信信号覆盖范围广、信号频带宽,在定位方面有一定的优势,也可弥补卫星导航的缺陷。在此背景下,通信和定位一体化系统开始出现,且在通信技术的发展中,两者的耦合程度也在不断提高。文中简述了这种一体化系统的原理、关键技术和发展趋势,希望能为其发展提供支持。

In recent years,under the promotion of market demand,satellite navigation has entered a stage of rapid deve-lopment,but its coverage performance in indoor scenes is poor,so it needs to be optimized.The communication signal has a wide coverage range and signal frequency bandwidth,which has certain advantages in positioning and can also make up for the shortcomings of satellite navigation.In this context,the integrated system of communication and positioning has begun to appear,and in the development of communication technology,the degree of coupling between the two is also constantly improving.This paper briefly describes the principle,key technologies and development trends of this integra-ted system,hoping to provide support for its development.
