HIGH PRECISION PREDICTION OF UNIVERSAL TIME BASED ON 100-YEAR DATA

摘要

A new method is proposed for predicting universal time based on constructing a general harmonic model for the earth's rotation and using a modified autoregression technique. A comparison of the predictions made at the Siberian State Research Institute of Metrology (SNIIM) and the International Earth Rotation and Reference Systems Service (IERS) during 2008-2009 shows that the former are more accurate. The efficiency of the new prediction technique for time support of the GLONASS system is demonstrated.
