Introduction

With the rapid development and widespread application of satellite navigation technologies, the demand and requirements for the performance of satellite navigation services are getting higher and higher, which promotes The satellite navigation enhancement technology has been gradually applied to various fields of application, thereby bringing about the increasing demand for the relevant standard specifications for satellite navigation enhancement technology Exuberant and urgent. This section focuses on the satellite navigation to enhance the information transmission interface requirements, in the preparation of the process to take full account of China's Wei Star navigation technology development and practical application, and with reference to RTCM10410.1 "Internet-based RTCM data network transmission (Nt- rip) ". The main difference between this section and Ntrip2.0 is that. a) "Satellite navigation enhances the transmission of information to the Internet Part 2. Interface requirements"; b) The scope of preparation according to our standard requirements; c) Added Chapter 2, "Normative References," citing the national and international standards used in the standard; d) Added Chapter 3 "Terms and Definitions, Abbreviations," defines terms such as mount point, header, headerline, etc. Abbreviation; e) Chapter 4, "System Architecture", which combines 1.3 "System Concepts" in Ntrip 2.0 and 1.4 "System Features" in the Cost section, Is defined as a network entity, given a new type of network entity topology, and network entities are divided into data sources, the number of According to server, broadcast server, user node; f) Clarified the specific data sources of this part Enhanced information and data transmission format see GB/T 34966.3; g) In Chapter 5, "HTTP-based Interface Requirements," the header and headerline categories have been added as tabs

Introduction

h) Add a new section to explain the role and mode of HTTP authentication; i) For the RTP communications, instead of establishing a connection, start the transmission and the end of transmission three stages; j) Data sources only support GNSS corrections; k) An informative annex has been added, respectively, given the user node and broadcast server, data server and broadcast server HTTP communication examples of the realization. Satellite Navigation Enhances Information Internet Transmission Part 2. Interface requirements

1 Scope

GB/T 34966 provisions of this part of the network-based satellite navigation to enhance information and data transmission interface requirements, including network structure, HTTP-based interface requirements, RTSP-based interface requirements, RTP-based interface requirements, source information table and so on. This section applies to the Internet in the satellite navigation environment to enhance information transmission interface design and implementation.
