GNSS data conversion


The Alberding DataConv software is used for real-time conversion of GNSS raw data streams into standard formats (e.g. RTCM 2.x, RTCM 3.x). Conversion of RTCM data to GNSS manufacturer formats (e.g. CMR+) is also supported.

Typical applications of DataConv are the conversion of SBAS data (e.g. EGNOS) into RTCM 2.x correction data and the conversion of GNSS receiver data into RTCM 3.x data format. DataConv supports the raw data formats of various GNSS receiver manufacturers (e.g. Trimble, Leica, Topcon, NovAtel, Septentrio, etc.).


In order to avoid problems with the conversion of proprietary formats of individual GNSS receiver manufacturers, the RINEX format was developed for post-processing applications. RINEX files are the input data for numerous post-processing software packages. However, the data is not always available in RINEX format or has been converted to RINEX with different software.

Alberding GmbH offers two RINEX conversion tools, makeRINEX and manyRINEX, for the conversion of GNSS raw data into the RINEX format. Alberding GmbH always keeps the conversion tools up-to-date by cooperating with internationally active authorities (e.g. BKG).

Some selected features:

  • Support of raw data input (Trimble, Topcon, Javad, Ashtech, Leica, NovAtel, Septentrio, Hemisphere GNSS, Turborogue, SIRF, u-blox, NVS, etc.).
  • Support of GPS, GLONASS, Galileo, BeiDou and QZSS observables.
  • Real-time correction data output in RTCM 2.x, 3.x and Trimble CMR or CMR+ formats.
  • Generation of RINEX v.2 and RINEX v.3 format output files.
  • Conversion of SBAS DGNSS corrections into RTCM.
  • Support of data communication via serial ports, TCP and UDP ports, Ntrip and NtripS.
  • Import data from log files.
  • Customer specific adaptations are possible.
