Abstract
In this paper, 2008-2010 global VLBI observation data is solved with OCCAM 6.2 software, from which the polar motion and polar motion rate results were obtained Using the above results, the regular pattern of the amplitude is summarized, and so are the phase and rate of polar motion in the recent three years. Finally, the power spectrums of the amplitude, phase and rate of polar motion are concluded with the maximum entropy spectral analysis to study the periods. And conclusions are presented.
