Analysis of EOP Determination via Chinese VLBI Network

    Graphical Abstract
    • Abstract
  • The EOPs are determined from the IVS observations which Sheshan Station in Shanghai and Nanshan Station in Urumqi were involved.The results show that the precision is comparable to the IERS EOP series,and the current precision of UT1 determined from single baseline observations of the two stations is in the middle level of the international.However,with the development of the technologies of software and hardware,the EOP precision for observations of the two stations is improving year by year.Besides,the determination precisions of UT1 either from the IVS intensive observations in 2011 with Sheshan jointed in or from international EOP observations with the two stations jointed in,can meet the requirements of the 100-m positioning precision of satellite of Mars to UT1.
