Comparaison des logiciels de traitement de données GPS GAMIT/GLOBK et PPP et validation du logiciel PPP

Abstract : Permanent GPS sites are increasingly appearing all around of the world, which results in making a soaring amount of data to analyse. The GAMIT/GLOBK GPS processing software has shown its efficiency at measuring the Global crustal deformation with bias of a few tenths of a millimeter per year for quite long time-series. The PPP processing software is an alternative to conventional GPS methods because it allows a faster and more economical (computing power) solutions computing. The aim of this study has been to validate the PPP software as compared to a reference processing software as GAMIT/GLOBK. For this, I computed a set of data of 21 GPS sites of the Eurasian plate, by calculating with both softwares, coordinates time series , in order to determine velocity estimates by least squares method to be compared. After several tests, I was able to validate the software due to satisfactory results (velocity results) derived from PPP processing.
