T/SSMT 5-2021 Real-time precise single-point positioning and regional enhancement technology data interaction format

Scope

Scope: This document specifies the data interaction protocol and testing methods for Precise Point Positioning (PPP) and Precise Point Positioning - Real-Time Kinematic (PPP-RTK) technologies supporting the Beidou Navigation Satellite System (BDS), Global Navigation Satellite System (GPS), Global Navigation Satellite System (GLONASS), and Galileo Navigation Satellite System (Galileo). This document is applicable to the data interaction and processing of PPP, PPP-RTK, and regional augmentation technologies supporting BDS, GPS, GLONASS, and Galileo systems. Main technical content: With the increasing maturity of BDS and the growing demand for PPP and PPP-RTK applications, this document is developed to specify a standard interaction format for public data, facilitating compatibility with equipment from different manufacturers and promoting the widespread application of real-time precise point positioning technologies and regional augmentation technologies. This document is a data interaction protocol for PPP and PPP-RTK technologies supporting BDS and compatible with other GNSS satellite navigation systems, mainly including: the coding format of real-time precise orbit and precise clock difference based on network/satellite broadcasting, the coding format of real-time non-differential correction numbers based on PPP-RTK technology for satellite observations, and the coding format of real-time satellite-side phase fraction (UPD).
