EUREF LAC Analysis at swisstopo/CODE Using the Bernese GPS Software Version 5.0

摘要

The EUREF LAC processing scheme at swisstopo was changed from Version 4.2 to Version 5.0 based on the BPE example RNX2SNX, which is included in the new release of the Bernese GPS Software. This update was also used as an opportunity to review the general processing environment, e.g. data management, and to adjust some processing options. The influence of these changes on the results will be presented by comparing the analysis resulting from the two versions 4.2 and 5.0. For this purpose, several weeks of EUREF GPS data are processed parallel. Of particular importance are the treatment of troposphere parameters, the antenna phase center models, and the settings for the options of the normal equation stacking program ADDNEQ2. Since September 2004, the collaboration between swisstopo and the Astronomical Institute of the University of Berne (AIUB) has become more extensive, thus gaining synergies, increasing the transfer of know-how, and considerably reducing duplicate work related to routine GNSS data analysis.
