La prise en compte des effets de charges dans le traitement des données GPS

Abstract : Crustal deformation sustained over time. These distortions are due to the loading effects and affect the position of GPS points. The aim of our study is to identify, quantify and correct variations using loading model previously defined. The studied network consists of 115 stations , we studied the different variability over a period of 10 years (January 1st , 2005 to December 31th, 2015), using the software GAMIT. We conducted three calculations, gross GPS calculation and two with two different models. After analysis of time series of stations in our network as a result, taking into account the loading effects in the GPS data processing, allows to gain precision of a few millimeters on the three components of North, East, and Up.
