This paper presents a hybrid prediction approach based on Dynamic Mode Decomposition principle and designed to improve 30-day forecasts of the celestial pole offset (CPO), expressed through its components dX and dY. We assess the method in an experimental framework referenced to the IERS EOP 14 C04 and IERS EOP 20 C04 series. The procedure also incorporates the JPL dX, dY time series as an auxiliary input, used as a supplement...

Predicting Earth Orientation Parameters (EOP) is crucial for precise positioning and navigation both on the Earth’s surface and in space. In recent years, many approaches have been developed to forecast EOP, incorporating observed EOP as well as information on the effective angular momentum (EAM) derived from numerical models of the atmosphere, oceans, and land-surface dynamics. The Second Earth Orientation Parameters Predicti...

Accurate, short-term predictions of Earth orientation parameters (EOP) are needed for many real-time applications including precise tracking and navigation of interplanetary spacecraft, climate forecasting, and disaster prevention. Out of the EOP, the LOD (length of day), which represents the changes in the Earth’s rotation rate, is the most challenging to predict since it is largely affected by the torques associated with cha...
