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 2. China Mobile Multimedia Broadcasting
1 Scope
