RINEX 3.04 Now Available
As announced by RINEX Working Group Chairman Ken MacLeod (of Natural Resources Canada) in IGSMAIL-7713, The International GNSS Service (IGS) and Radio Technical Commission Maritime Service, Special Committee -104 (RTCM SC-104) RINEX Working Group announce the availability of RINEX 3.04.

The Receiver INdependent EXchange (RINEX) is an internationally recognized Global Navigation Satellite System (GNSS) observation and navigation data format. The first version of RINEX was developed in 1989, to support a European, Global Positioning System (GPS) data collection campaign. The key objective was to develop an open and human readable (ASCII) GNSS data format that removed the need of specialized decoders/interpreters for each GNSS receiver type. Under the leadership of Werner Gurtner (Astronomical Institute, University of Bern, Switzerland) and Lou Estey (UNAVCO, Boulder, Colorado, USA), RINEX evolved from version 1 to 2 and then to 3. Since 2013 (RINEX Version 3.02) the RINEX GNSS format has been maintained by the RINEX Working Group, which consists of members from the International GNSS Service (IGS), Radio Technical Commission for Maritime Service, Special Committee 104 (RTCM-SC104) and the GNSS industry.

The current RINEX 3.04 release supports all publicly available signals, including the United States’ GPS, Russia’s GLONASS, Europe’s Galileo, China’s BeiDou, Japan’s Quasi Zenith Satellite System (QZSS) and the Indian Regional Navigation Satellite System (IRNSS) constellations. RINEX 3.04 contains updates to support planned GLONASS CDMA signals, as well as new BeiDou III and QZSS II signals. In addition to the new signals, the RINEX 3.04 text has been edited to improve the description of messages, fields and overall readability. The RINEX 3.04 data standard documentation is available from the following addresses:, and—dgnss—standards.html.
