摘要

通导一体化是现代卫星通信与导航领域的重要发展方向。低轨巨型通信星座的迅速发展提供了丰富的载荷、链路和终端资源，以及强大的通信覆盖及信息传输能力，同时利用低轨星座几何构型变化快、落地功率强等特点，可实现对现有导航系统的补充、备份和增强，从而提供覆盖更广、精度更高且更为稳健的通信与导航服务。低轨卫星通导一体化系统中，发送信号设计及接收信号处理是实现高效通信与高精度导航的关键环节。为此，首先梳理低轨卫星通导融合的演进过程；其次，围绕发送信号设计和接收信号处理，重点阐述帧结构和接收机设计的相关方案；最后，探讨未来所面临的挑战及潜在解决方案。

Abstract

The integration of communication and navigation is an important direction in modern satellite communication and navigation fields.The advancement of low earth orbit (LEO) mega-constellations provides the abundant load

link and terminal resources

as well as the powerful communication coverage and information transmission capabilities.Moreover

together with the fast-changing geometric configuration and strong power

the LEO satellites can complement

backup

and enhance the existing navigation systems to provide communication and navigation services with broader coverage

higher precision and reliability.In the LEO satellite-enabled communication and navigation-integrated system

the design of the transmitted signals and the processing of the received signals are crucial for achieving efficient communication and high-precision navigation.To this end

the evolution process of the communication and navigation fusion was first outlined.Then

it focused on the design of transmitting signals and the processing of receiving signals

the relevant schemes included the layout of the frame structure and the receiver were emphasized

respectively.Finally

the challenges and potential solutions that lie ahead in the future were explored.
