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 are broadcasted through satellite, mobile communication networks, digital broadcasting, etc., and a series of standards are formed accordingly. The first part is the mobile communication network. The second part is China Mobile Multimedia Broadcasting, and the third part is FM frequency band digital audio broadcasting. Follow-up will be based on the new broadcast method Use, increase the corresponding standard. BDS's data products are products that should be broadcasted by satellite navigation ground-based augmentation systems, data products from GLONASS, GPS, and Galileo. For the purpose of selecting the broadcast content. Satellite navigation ground enhancement system broadcast interface specification Part 3. FM band digital audio broadcasting

1 Scope

This part of GB/T 37019 specifies that satellite navigation ground enhancement systems use FM band digital audio broadcasting to broadcast BDS/GLO- NASS/GPS wide-area differential, BDS/GLONASS/GPS/Galileo regional RTD differential, BDS/GLONASS/GPS/Galileo The ephemeris assists in the positioning of data products, the distribution process, interface protocols, interface requirements, data product classification, packaging, and so on. This part is applicable to the data product broadcast and user terminal development of satellite navigation ground enhancement system.
