GPS (RINEX) data and IGS precise ephemeris

Currently we archive data for 27 IGS stations, and 1 regional station (NAMI). The archive covers the period from January 1998 to present:

  • HRAO (HartRAO, Hartebeesthoek, South Africa [HRAO/JPL])
  • HARB (SAC, Hartebeesthoek, South Africa [CNES])
  • SUTH (Global IGS station, SAAO, Sutherland, South Africa [HRAO/JPL])
  • SUTM (SAAO, Sutherland, South Africa [GFZ/SAAO])
  • RBAY (Richardsbay, South Africa, [HRAO/JPL])
  • SIMO (Simonstown, South Africa, [HRAO/JPL])
  • ASC1 (Ascension Island [JPL])
  • MALI (Malindi, Kenya [ESA/ESOC])
  • OHI2 (O'Higgins, Antarctic Peninsula [BKG])
  • DAV1 (Davis, Antarctica [AUSLIG])
  • KERG (Port aux Francais, Kerguelen Islands [CNES])
  • VESL (SANAE IV, Antarctica [AWI])
  • GOUG (Gough Island [AWI])
  • MAW1 (Mawson, Antarctica [AUSLIG])
  • PALM (Palmer, Antarctica [])
  • NAMI (Windhoek, Namibia [HRAO/JPL])
  • SEY1 (La Misere, Seychelles [JPL/IDA])
  • YKRO (Yamoussoukro, Cote D'ivorie [NASA/JPL])
  • CAS1 (Casey, Antarctica [AUSLIG])
  • TGCV (Tide Gauge at Cape Verde [Pacific GPS Facility])
  • LPGS (La Plata, Argentina [GFZ, Potsdam])
  • MBAR (Mbarara, Uganda [JPL])
  • MAS1 (Maspolomas, Gran Canaria [ESA/ESOC])
  • MSKU (Masuku, Franceville, Gabon [JPL])
  • NKLG (N'Koltang, Libreville, Gabon [CNES])
  • RABT (Rabat, Morocco [UNAVCO])
  • SYOG (Syowa, Antarctica [Geographical Survey Institute, Japan])
  • ZAMB (Lusaka, Zambia [HRAO/JPL])

The RINEX data is archived in the structure year/doy (day of year). Therefore to retrieve data for (say) February 5, 1998, you should access the data stored under 1998/036. IGS products are stored per GPSweek. If you have any problems regarding data or product retrieval, or would like to have other data or products added, please contact me. If you have used this archive, please e-mail me so that I can add your details to our database. This will allow us to inform you of any important changes to this site or allow us to inform you about events in geodesy which might possibly interest you.

You can access a data holdings summary, which is structured by year. The most current file is updated daily. Please keep in mind that some stations tend to be later than others, especially those located on very remote sites. Data files which in general are not available after a week, probably means that the station involved was down for that period.

The most recent log files for the IGS stations can be downloaded from here.

Files with a .gz extention have been compressed with gzip. On UNIX or LINUX platforms they can be expanded with the 'uncompress' or 'gzip' command. There is a DOS gzip utility available for download.

GNSS Basestation Velocities

Global Navigation Satellite System (GNSS) basestations using signals from GPS and GLONASS measure positions at cm levels and so show tectonic plate motion when monitored on long timescales. Several HartRAO-operated GNSS basestations appear in this station velocity map created by the Jet Propulsion Laboratory (JPL).

HartRAO and collaborators operate base stations used by the International Global Navigation Satellite System Service (IGS) that are listed below.
