Abstract
The difference between the new format and standard NGS format is introduced;and the data of 2005-2007 which is downloaded from IVS is transfered to the standard format.With OCCAM 6.2 software developed by Norwegian Geodetic Institute and institute of geoscience in Australia,the parameters of geodetic interest(Xp,Yp,UT1-UTC,dψ,dε) are computed.In the data processing,the results with different interpolation models of UT1 are compared.The difference in accuracy is analyzed;and some conclusions are drawn.
