Network system, data processing center, operation service platform, data broadcasting system, user terminal, information security protection system, backup system, etc. composition. The Beidou ground-based augmentation system receives navigation signals transmitted by navigation satellites through several reference stations established on the ground at a certain distance. The information network is transmitted to the data processing center, and after processing, the orbit correction number of the navigation satellite, the clock error correction number, the ionospheric correction number, and the regional difference are generated. Data, millimeter-level post-processing data and other data products are broadcast through satellite, digital network (mobile communication network, Internet, etc.), digital broadcasting, etc. It provides download services of post-processing data products through the Internet to meet the wide-area meter and decimeter level within the scope of the Beidou ground-based augmentation system. Real-time positioning and navigation requirements at the centimeter level, regional centimeter level, and post-processing millimeter-level positioning service requirements. In order to systematically optimize, upgrade and solidify the Beidou ground-based enhancement system base station, communication network, data processing, data interface, data broadcast The main technologies such as development and operation services have enabled these technologies to provide technical support and useful guidance for similar construction projects at home and abroad, and have established the "Beidou Technical Specifications for the Construction and Acceptance of Base Stations of Ground-based Enhancement System Part 1.Construction Specifications "Beidou Ground-based Enhancement System Base Station Construction and Inspection Acceptance Technical Specifications Part 2.Acceptance Specifications" "Beidou Ground-based Augmentation System Communication Network System Technical Specifications" "Beidou Ground-based Augmentation System Number According to the technical requirements of the processing center", "Satellite Navigation Ground-based Augmentation System Data Processing Center Data Interface Specification", "Satellite Navigation Ground-based Augmentation System Broadcast Transmission Interface Specification Part 1.Mobile Communication Network "Satellite Navigation Ground-based Augmentation System Broadcast Interface Specification Part 2.China Mobile Multimedia Broadcasting” “Satellite Navigation Ground-based Augmentation System Broadcast Interface Specification Part 3.FM Frequency Band Digital Audio Broadcasting” “Beidou Ground-based Augmentation System The Beidou Ground-based Enhancement System is a series of standards that support each other, coordinate and support each other, which is composed of national standards such as "Technical Requirements for Access to the Network of Standard Reference Stations". This document systematically stipulates the network access content of the base station of the Beidou ground-based enhancement system, which is the network access of the base station of the Beidou ground-based enhancement system. Provide basis for qualification review, construction and test evaluation. Technical requirements for the network access of the reference station of the Beidou foundation enhancement system1 ScopeThis document specifies the technical requirements, operation and maintenance capability requirements, security and confidentiality requirements, and entry requirements for reference stations that apply to join the Beidou ground-based enhancement system. Network management process, network access application and assessment procedures, network access inspection and testing requirements and other content and technical requirements. This document is applicable to the review, testing and evaluation of the network access qualifications of reference stations that apply to join the Beidou Foundation Enhancement System. Apply to join North The monitoring station of the bucket foundation enhancement system is also used as a reference.2 Normative referencesThe contents of the following documents constitute the indispensable clauses of this document through normative references in the text.
