| Abstract: | Positioning, navigation and timing (PNT) systems are indispensable infrastructures for ensuring the normal operation of modern society. In order to provide reliable PNT information services, it is necessary to develop PNT systems that do not rely on satellite navigation. This paper introduces the development of land-based ultra-long-range radio navigation systems domestic and abroad, and puts forward the architecture, key technologies and development proposals for developing land-based ultra-long-range very low frequency radio systems. Land-based ultra-long-range navigation systems can provide backup when satellite navigation is unavailable. For building redundant and reliable national PNT system, it is of great significance to ensure the safety and reliability of PNT information. |
