The Bernese GNSS software or Berner GPS software is a program system for evaluating GPS and other GNSS satellite observations. On the one hand, it is used to determine the orbit of these navigation satellites and, on the other hand, to precisely determine the location of the measuring and satellite stations . In addition, it enables the calculation of models of the earth's atmosphere , the earth's rotation and other earth and satellite-related parameters.

Range of use

The software package is installed at over 600 institutions worldwide, including around 400 research institutes and their computer centers, as well as national surveying offices and large surveying offices . In addition to the location of points on the earth's surface, it is an important tool for orbital analysis of geodetic satellites , the international IGS railway service and IERS monitoring of the earth's rotation. Special model calculations for meteorology ( troposphere and ionosphere ) and geodynamics ( plate tectonics , seismology, etc.) are also possible; other applications relate to the maintenance of permanent networks of GNSS receivers (e.g. for RTK online locations and in the construction industry) and time services high precision.

Basic features of the Bernese GPS software (currently in version 5.2) are

  • mathematical modeling based on the latest technology and international standards
  • detailed control of all relevant evaluation options / model parameters.
  • flexible automation through the modular structure of the program system.

Development history

The system was initiated in the 1980s by Gerhard Beutler at the Astronomical Institute of the University of Bern and the main features of it were programmed at the institute. Long-term employees of the BSW team were a. W. Gurtner, Stefan Schaer, Markus Rothacher , Urs Hugentobler , Pierre Fridez, R. Dach and P. Walser. Groundbreaking was the exact consideration of the latest nutation theory of the earth's rotation and various possibilities of perturbation calculation as well as other influences, u. a. the earth's atmosphere and geodynamics .

The Bernese GPS software has been (and is) continuously developed. This was done with the participation of numerous experts from other universities such as the TU Vienna and Graz (Robert Weber, T. Pany, G. Stangl), the TU Munich (M. Rothacher, R. Schmid), the GFZ (P. Steigenberger, H. Habrich), the ESA , the Czech Academy (Leos Mervart, J. Dousa, J. Kouba) and other institutes (J. Beavan, J. Bosy, E. Brockmann, D. Darmawan, P. Clarke, M. Greaves, J Johnson, Tim Springer, P. Willis et al).

As early as the 1990s, the software achieved orbital accuracies in the decimeter range - which at high satellite speeds also requires time systems in the micro and nano range - and now even centimeter accuracies are standard. The software is used at over 200 research institutes and data centers and is an important basis for orbital analysis of geodetic satellites , the international IGS railway service and IERS monitoring of the earth's rotation. The software package has also been used successfully at various IGS and EUREF analysis centers.

License model

The software is not "free software". The software license differentiates between commercial use (commercial license) and research-oriented use (research license). Depending on the intended use, a user buys one or the other license. A research license does not allow any commercial use, but can also be used commercially by converting it to commercial for a price of several thousand Swiss francs per seat.
