    • Abstract
  • The GPS signal multipath effects is considered as a major error sources for the high-precision real-time dynamic deformation monitoring.The trend being extracted from the three-dimensional coordinate series are multipath model by using empirical mode decomposition(EMD) method;The research demonstrates that the multipath effects have strong correlation between two successive days,and after the coordinate series being corrected through the first day's multipath model,the new coordinate series generate.The result shows that the stability and the accuracy are markedly improved after multipath effects being removed.
