Conceptual Framework and Research Progress on Communication and Navigation Integration

Communication and navigation integration is an important part and key direction of integrated PNT system.The concept of communication and navigation integration is discussed, and the concept of flexible integration of communication and navigation is proposed. The architecture of communication and navigation integration networked PNT system is proposed to meet the needs of the integrated PNT system. The research progress of communication and navigation integration is explained, and a comprehens-ive and systematic analysis is carried out from the perspectives of communication and navigation integ-ration signal design, channel model, signal processing, network architecture, network management, etc. Typical achievements such as low earth orbit communication and navigation integration, regional self-organizing communication and navigation integration network, and 5G+UWB collaboration are introduced. The future development directions are prospected, including network-information-field-map, intelligent network management, game confrontation, etc.
