| Abstract: | Data communication is an indispensable part of improving the navigation accuracy and positioning accuracy of the Beidou GBAS, and plays a key role in the system. Based on the Beidou GBAS, the paper gives a brief introduction to the system, and discusses the TCP／IP and RS232 mode used by the reference station and the data center for data communication. For the user and data center, the paper analysis of the NMEA0183 information, NRTIP and RTCM data, describes the improvement of RTCM3.2 over the previous version. Finally, the paper summaries the role of data communication in Beidou GBAS, and prospects the application foreground. |
