Possible enhancement of Earth’s polar motion predictions using a wavelet-based preprocessing procedure

Studia Geophysica et Geodaetica, 2018
Earth’s polar motion predictions are essential in near real-time applications including spacecraft navigation and satellite orbit determinations and are also important for geophysics studies. It has previously been demonstrated that the basic problem in predicting a polar motion time-series is to treat separately its low- and high-frequency components.

Optimizing the Input of Liouville Convolution Improves the 10 Day Predictions of Polar Motion

Research in Astronomy and Astrophysics
Abstract This study addresses the critical technical need to enhance the 1–10 day prediction accuracy of polar motion (PM) in satellite autonomous navigation and deep space exploration, with a focus on optimizing the convolution input accuracy within the least squares and autoregression with effective angular momentum (LS+AR+EAM) method.

Impact of GFZ’s Effective Angular Momentum Forecasts on Polar Motion Prediction

2017
The Earth System Modelling group at GeoForschungsZentrum (GFZ) Potsdam offers now 6-day forecasts of Earth rotation excitation due to atmospheric, oceanic, and hydrologic angular momentum changes that are consistent with its 40 years-long EAM series. Those EAM forecasts are characterized by an improved long-term consistency due to the introduction of a
