Conversion of Raw Observation Data and Navigation Message Data to RINEX

If your GPS/ GLONASS receiver outputs raw measurements such as pseudorange, (integrated) carrier phase, Doppler, and/ or satellite navigation message data such as satellite ephemeris parameters, satellite clock correction parameters, iono delay parameters, you can calculate (differential) position.

Position calculation software packages often require input of measurement data and navigation message data in RINEX, or the Receiver Independent Exchange Format (http://www.ngs.noaa.gov/CORS/Rinex2.html). RINEX supports six output file types:

  1. Observation data file: contains measurement data
  2. Navigation message file: contains ephemeris, sat clock and iono parameters
  3. Meteorological data file: meteo data (ambient pressure, temperature and humidity) for high accuracy post processing
  4. GLONASS navigation message file
  5. GEO navigation message file (WAAS, EGNOS geostationary satellites)
  6. Satellite and receiver clock data file

High end receivers often output their data directly in the RINEX format, or are offered with software to convert the receiver data to RINEX. Low end receivers such as handheld and OEM receivers usually don't.

Many (geodetic) reference stations (see e.g. http://www.ngs.noaa.gov/CORS/ for the USA, and there are many reference station in other parts of the world) deliver data in the RINEX format. You can download observation data and/ or navigation message data from one or more reference station for differential processing of your receiver data.

Your low end receiver may be supported by TEQC: The Toolkit for GPS/GLONASS Data (http://www.unavco.org/facility/software/teqc/teqc.html). Use this freeware to convert your data to RINEX, and check your data quality.

If  TEQC does not support your receiver, or if you have other reasons not to use TEQC, we may be able to help you.

Currently we have converter packages for the following single frequency (L1) receivers:

Receiver data logging

Helenav recommends the Windows freeware logger REALTERM (http://realterm.sourceforge.net/).
On request we supply a simple DOS logger with your order.

Operating system

All packages operate under DOS 5.0 or higher, and in a DOS box in Windows.

Prices

All prices include 19% VAT. A one page user manual and sample i/o data is bundled with the converter.

You will receive 15% discount when you order two or more converters.

Please send your order by e-mail to us.
