Application and prospect of 5G-A/6G+Beidou communication, sensing and navigation technology in low-altitude economy

As a national strategic emerging industry, the low-altitude economy will usher in significant development opportunities. However, the infrastructure required for low-altitude activities, such as communication, sensing, and navigation, are not yet fully developed. 5G-A/6G integrated sensing and communication (ISAC) technology and Beidou integrated communication and navigation (ICAN) technology in low-altitude intelligent network were focused on, their key technologies and integration ideas, as well as their applications and future research directions in low-altitude economy were analyzed. Firstly, 5G-A/6G ISAC and Beidou ICAN technologies were introduced, and the integration of communication, sensing, and navigation technologies based on communication base stations were discussed. Secondly, the application scenarios of communication, sensing, navigation positioning, and timing technologies in low-altitude economy were studied. Finally, the future research directions of communication, sensing, and navigation technologies for low-altitude economic were discussed.
