Introduction

With the development of satellite navigation technology, global navigation satellite system (GNSS) service performance continues to improve, and the application of GNSS compatible receivers The scope of application is getting wider and wider. In order to realize the independent exchange and joint processing of data between different receivers, the international GNSS service (Interna-tionalGNSSService, IGS) organization, International Maritime Organization (RTCM-SC104) professional committee and International Geodesy Association (Inter-nationalAssociationofGeodesy, IAG) jointly formulated the Receiver Data Autonomous Exchange Format (the Receiver INdependentEXchangeformat, RINEX)" document, the data exchange format specified by the document is universal and flexible. Points, so it has been widely used.

Since 2011, in addition to GPS, GLONASS, GALILEO, BDS, SBAS and other five types of systems, The two systems QZSS and IRNSS have been put into operation, and the navigation signals, service methods, and regulatory documents of each GNSS system are not available.

Continuous improvement and perfection, the internationally accepted standard format "ReceiverIndependentExchangeFormat" referred to in the standard technical content (RINEX) has also been updated several times, and the latest public release version is V 3.04 in November 2018. According to my country's Beidou Satellite The latest situation of the construction and development of the navigation system, and the latest technological update requirements for the development and use of the receiver, it is necessary to amend GB/T 27606-2011. GNSS receiver data autonomous exchange format

1 Scope

This standard specifies the type, structure, name, and data record format of GNSS receiver data autonomous exchange files.

This standard is applicable to the exchange and data exchange of receivers such as BDS, GPS, GLONASS, GALILEO, QZSS, IRNSS and SBAS. Unified processing.
