Abstract
In this paper, the polar motion series is obtained by processing the 09-10 VLBI data downloaded from IVS. The precision of the polar motion series is also been estimated. In order to extracting the periodical components of the polar motion series, the spectrum analysis method of FFT is applied to the polar motion series after interpolating and wavelet de-noising.
