Abstract

It is currently in the period of construction of the next generation of very long baseline interferometry (VLBI) systems. This is a good opportunity for Wuhan University satellite station. We count observation times of different stations and number of stations from 2006 to 2015. We process VLBI data from 2006 to 2015 to estimate Earth orientation parameters (EOP) using Vienna VLBI and satellite software (VieVS). Internal and external accord accuracy of EOP during 2006-2015 are credible. Ten years of changes of the length of day (△_LOP) are estimated and compared with the results of International Earth Rotation Service (IERS). The short (9.13 d), half-month (13.67 d), month (27.65 d), half-year (182.50 d) and year (365.00 d) periods of △_LOP are extracted with fourier analysis. The year, Chandler periods of polar motion and the free core nutation period of nutations correction are also extracted. This solution can accumulate some experience of VLBI data analysis for Wuhan University satellite station.
