The completion of the BeiDou navigation satellite system has promoted the pace of informatization construction and promoted the development of satellite navigation industry, basically satisfying the needs of users in China for positioning and navigation and timing (PNT) services. However, the service performance of global satellite navigation systems (GNSS) is seriously degraded or even unable to work in environments such as blocking and strong interference. Therefore, it is urgent to further enhance the capabilities of the BeiDou satellite navigation system, as well as to coordinate other types of PNT methods, and introduce new technologies, new systems and new methods so as to establish the BeiDou integrated PNT system. Based on the BeiDou integrated PNT system, the development trend of Beidou PNT application services was discussed, application service architecture is designed and researched, the suggestions for key development focus of application services is given out, with a view to contributing ideas and suggestions for the demonstration, construction, application, and service of Beidou integrated PNT system and for the development of Beidou integrated PNT application service industry and its coordinated development with high-tech, and lay the theoretical foundation for socio-economic structural transformation and upgrading. |
