EMPLOYING COMBINATION PROCEDURES TO SHORT-TIME EOP PREDICTION

ABSTRACT. A well known problem with Earth Orientation Parameters (EOP) pre-diction is that a prediction strategy proved to be the best for some testing time span and prediction length may not remain the same for other time intervals. In this paper, we consider possible strategies to combine EOP predictions computed using different anal-ysis techniques to obtain a final prediction with the best accuracy corresponding to the smallest prediction error of input predictions. It was found that this approach is most efficient for ultra-short-term EOP forecast
