This is an unofficial mirror of the GNSS-Lab Tool (gLAB) v5.5.1, an interactive educational software tool suite to process and analyse GNSS data. gLAB has been developed under an European Space Agency (ESA) contract by the Research Group of Astronomy and Geomatics (gAGE) from the Universitat Politecnica de Catalunya (UPC).
gLAB performs precise modeling of GNSS observables (pseudorange and carrier phase) at the centimetre level, allowing both standalone GPS positioning and PPP. Every single error contributor may be assessed independently, which, in turn, provides a major educational benefit. gLAB is adapted to a variety of standard formats like RINEX-3.00, SP3, ANTEX and SINEX files, among others. Moreover, functionality is also included for GPS, Galileo and GLONASS, allowing performing some data analysis with real multi-constellation data.
The gLAB software tool is quite flexible, able to run under Linux, Windows and Mac operating systems and is provided free of charge by ESA Education Office to universities and GNSS professionals.
