چکیده انگلیسی
In this paper the history and status of the IVS (International VLBI Service for Astrometry and Geodesy) UT1 Intensive observations are briefly re- viewed, and the deficiencies and error sources in the current Intensive observa- tions are investigated. An in-depth analysis of the IVS Intensive observation data from February 1984 to August 2011 with different observation networks is carried out, and the progress of the UT1 accuracy obtained by the Intensive observations during this period is discussed. By comparing the results from dif- ferent networks, a difference of some dozens of microseconds between different networks is found. The results of the IVS Intensive observations with Sheshan Station participated in are analyzed, it shows that the Sheshan Station perfor- mance as well as other stations. Finally, from the comparison and analysis of different UT1 series, it is concluded that there is an uncertainty with a level of 10 microseconds between the UT1 values obtained from the IVS Intensive observations and the values of the IERS (International Earth Rotation Service) C04.
