Introduction
The Satellite Navigation Ground Reinforcement System (NBAS) is a nationally important information infrastructure for high precision positioning and integrity
service.
The satellite navigation ground-based augmentation system receives navigation signals transmitted by navigation satellites through a number of reference stations established at a certain distance on the ground.
Transmission to the data processing center via the communication network, processing to generate precise orbits and clock differences of the navigation satellite, ionospheric correction, post-processing data
Products and other information, broadcast through satellite, mobile communication networks, digital broadcasting, etc., and provide download services for post-processing data products via the Internet.
To meet the real-time positioning and navigation requirements of wide-area meter-level and decimeter-level, regional centimeter-level within the scope of satellite navigation ground-based augmentation system services,
And post-processing requirements for millimeter-level positioning services.
This standard applies to the data processing center of the satellite navigation ground-based augmentation system and the base station, monitoring station and data distribution system.
Data interface relationship between heart and other data processing centers, transmission content and requirements, interface protocols, data product categories, message content and
The format is specified as data between the data processing center of the satellite navigation ground-based augmentation system and the base station, monitoring station, and data distribution system.
Provides a basis for data interaction between the processing center and other data processing centers. In the case of differential data product messages, this standard is based on
RTCM10403.3 and RTCM10402.4 have been expanded to customize some messages such as BDS and SSR to support satellite navigation.
High-precision positioning service for base-enhanced systems.
