15 Apr 2013 | | Abstract: | A new method has been developed at the Siberian Research Institute of
Metrology (SNIIM) for highly accurate prediction of UT1 and Pole coordinates.
The method is based on construction of a general polyharmonic model of the
variations of the Earth rotation parameters using all the data available for
the last 80-100 years, and modified autoregression technique. In this
presentation, a detailed comparison was made of real-time UT1 predictions
computed making use of this method in 2006-2010 with simultaneous predictions
computed at the International Earth Rotation and Reference Systems Service
(IERS). Obtained results have shown that proposed method provides better
accuracy at different prediction lengths. | | Source: | arXiv, 1304.3981 | | Services: | Forum | Review | PDF | Favorites | |
