Abstract:The coordinates and velocities of 260 CORS of CMONOC in the ITRF2008 are determined with the GAMIT/GLOBK and QOCA software. The comparative results of the two software show that, QOCA can deal with the non-linear change of station’s displacement, and improve the calculation precision by means of fitting the annual and semi-annual term, by eliminating common mode error and so on. Compared to GLOBK software, the RMS of fitting residual series acquired with QOCA decline by a factor of 70%, 80% and 70% in the N, E, U direction, respectively.
