EMD-based Analysis and Denoising of GPS Data

In this study Empirical Mode Decomposition zEMDgvbased dey noising of the Global Positioning System zGPSg data is exyploredFEMD is a dataydriven new technique which is proposed by Huang and improved by Flandrin and his colleaguesF For only while noise or only colored noise casesga denoising algoyrithm is proposed in literatureF This study expands the denoisying scheme for while p colored noise casegwhich is applicable to some real signals such as Global Positioning System zGPSg based geodetic time seriesF The results for synthetic data and real GPS data are presentedF
