GB/T 39783-2021Technical requirement for data processing center of BeiDou ground-based augmentation system (English PDF)

Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules of Standardization Documents" Drafting.

Introduction

The Beidou ground-based augmentation system is an important national information infrastructure used to provide high-precision positioning services.

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 content of the construction of the data processing center of the Beidou foundation enhancement system, which is the data processing center of the Beidou foundation enhancement system. Provide a basis for the construction of the management center.
