Downloading of the RINEX observation files of the GNSS stations of the CatNet network
About RINEX files
Geofons data server (ftp and https protocol) allows the download of 30 seconds daily RINEX files in version 3 (with observables from the constellations GPS, GLONASS, GALILEO and BEIDOU), for all those dates from June 5, 2017. 30 seconds daily RINEX files prior to this date can be downloaded in version 2, with different observables depending on the time and equipment installed at each station.
On this same Geofons server, 1 second RINEX files can also be downloaded, exclusively in version 3 (with observables from the constellations GPS, GLONASS, GALILEO and BEIDOU). These files are available for approximately one year from the date of observation.
The data is doubly compressed: a first Hatanaka compression and a final compression in binary format. Decompression tools can be downloaded from the rnxcmp directory.

The International GNSS Service publishes the documentation with the standards of the RINEX format for its different versions, for consultation and reference.

General structure
The files located at https://geofons.icgc.cat/rinex (version 2) and https://geofons.icgc.cat/rinex3 (version 3) are organized according to the structure:
/Tipus/RefData.YY/Month.MMM/Day.DD/
Where:
- Type:Â Â Indicates whether RINEX files are daily or hourly ('diari_30s' or 'horari_1s', respectively)
- RefData.YY:Â Â Indicates the year in which the data in the RINEX file was recorded (eg: year 2009 would be YY = 09)
- Month.MMM:Â Â Indicates the month in which the data in the RINEX file was recorded (eg: Month.Jul would be July)
- Day.DD:Â Â Indicates the day on which the data in the RINEX file was recorded
The Geofons data repository with FTP protocol (ftp://geofons.icgc.cat) is now also accessible via the HTTPS protocol (https://geofons.icgc.cat)
