Abstract
As the participants of Earth Orientation Parameters Combination of Prediction Pilot Project (EOPC PPP), Sternberg Astronomical Institute of Moscow State University (SAI) and Shanghai Astronomical Observatory (SHAO) have accumulated ∼1800 days of Earth Orientation Parameters (EOP) predictions since 2012 till 2017, which were up to 90 days into the future, and made by four techniques: auto-regression (AR), least squares collocation (LSC), and neural network (NNET) forecasts from SAI, and least-squares plus auto-regression (LS + AR) forecast from SHAO. The predictions were finally combined into SAI-SHAO COMB EOP prediction. In this work we present five-year real-time statistics of the combined prediction and compare it with the uncertainties of IERS bulletin A predictions made by USNO.
