Improving the accuracy of polar motion prediction using a hybrid least squares and long short-term memory model Open
Earth rotation parameters (ERPs) are essential for transforming between the celestial and terrestrial reference frames, and for high-precision space navigation and positioning. Among the ERPs, polar motion (PM) is a critical parameter for …

Higher order ionospheric effects in testing gravitational redshift by space frequency signal transfer Open
Context. When a microwave passes through the ionosphere, it produces ionospheric refraction and path bending, leading to changes in frequency and reducing the accuracy of frequency transmission. Currently, the Atomic Clock Ensemble in Spac…
