Rinex data

Access to the RINEX data

• RINEX3 files in crinex format compressed to gz.
• 30 second daily Rinex in the Year directory, and 1 second hourly Rinex in the Day of the Year directory. There are also files fragmented by hours, according to the UTC time base.
• RINEX v3.x file format:
  

  
  Denomination: XXXXMRCCC_S_YYYYDDDHHMM_PPU_DDU_TT.FFF.CCC
  Example: PASA01ESP_R_20191180000_01D_30S_MO.crx.gz
  
  XXXXMRCCC: Station Name (XXXX), Monument number (M), Receiver number (R) and country ISO code (CCC).
  S: Data source (Receiver, Streaming, etc.) for the generation of observations.
  YYYYDDDHHMM: Data start time (YYYY: year; DDD: day of the year; HH: hour; MM: minute).
  PPU: Duration of the data (PP) and units (U) (minutes, hours, days, years, etc.) of the file.
  DDU: Recording frequency (DD) and units (U) (seconds, minutes, hours, days, etc.) of the file.
  TT: Type of data (Mixed Observations (OM), Meteorological (MM), etc.) of the file.
  FFF: File Format (RINEX: rnx, Hatanaka: crx, etc.).
  CCC: File Compression (gz, zip, etc.).
  

• Transformation of RINEX v3 files to RINEX v2:
  

  
  1) Uncompress the *gz file, using any standard compression/decompression software (gzip, winzip, 7-zip, etc.)
  2) Decompress the file with Hatanaka compression *.crx, using “CRX2RNX” software, obtaining a *.rnx file as a result. It can be downloaded from the link: https://terras.gsi.go.jp/ja/crx2rnx.html .
  3) Convert RNX3 file to RNX2, using the "GFZRNX" software, which can be downloaded from the following link: https://gnss.gfz-potsdam.de/services/gfzrnx
  
  All these steps can be done by downloading this file from ItaCyL from the link: http://ftp.itacyl.es/Red_GNSS/Informacion/RINEX3-RINEX2.zip , which unzips the indicated programs into a "RINEX3-RINEX2" directory and a "RINEX3-RINEX2.bat" file that, when executed, transform all the files that we copy in that folder, to Rinex v2.11.
