GNSS Signal Monitoring Station

The construction of the GNSS monitoring station was planned in several phases. In the first phase the monitoring station provides monitoring all in view GPS, EGNOS, and Galileo satellites on LI frequency. The monitored data are stored in raw form. Data are also transformed to the standard format and analyzed. The PEGASUS software tool analyzes raw GNSS and SBAS data streams and giving the possibility of easy access to the data processing with graphical presentation of the results. The raw form of monitored data is stored in PC workstation to keep available all information for measurement analyses. Monitoring station provides data via internet as well. In the next phase the capability of monitoring of the Galileo E5, GPS L2 CA, and GPS L5 signals will be implemented. Since standard format supports only subset of the raw measurement information the project will continue in development of special software that directly processes raw data measurements.
