With the increasing improvement of BDS and the increasing demand for PPP and PPP-RTK applications, this document has been compiled to specify the standard interactive format of public data to facilitate compatibility with equipment from different manufacturers and to facilitate the development of real-time precision single-point positioning technology and regional enhancement technology. Wide range of applications. This document is a data exchange protocol suitable for PPP and PPP-RTK technology that supports BDS and is compatible with other GNSS satellite navigation systems. It mainly includes: real-time precision orbit based on network/satellite-based broadcast, coding format of precision clock error, coding format based on The real-time non-difference correction number encoding format of satellite observations in PPP-RTK technology and the encoding format of real-time satellite phase decimal (UPD).
