Geodesy. The estimation of the Length of the Day parameter (LOD) is introduced using the assumption that the values of other
high correlated parameters are fixed. The outcome values of the estimated LOD parameter for the nine-year period are compared
with the reference model IERS C04 provided by the International Earth Rotation and Reference Systems Service. The mean
residual value between the LOD parameter determined from DORIS measurements and the value obtained from the IERS C04
model is 0.03 ms and the standard deviation is 0.15 ms. Using spectral and harmonic analysis, we compared the periods
and amplitudes of the LOD time series, obtained from DORIS measurement and the reference model. Based on our results
the amplitude of the semi-annual period signal is almost identical to IERS CO4 model whilst the amplitude of the annual
period signal differs by 10 %. In case of difference between DORIS and IERS C04 the annual period represents a dominant
signal."
