Geocenter Motion Estimated from GPS Array Observations Using Optimal Sequence Estimation

This dataset provides daily geocenter motion time series derived from global GPS array observations using the Optimal Sequence Estimation (OSE) method. The geocenter motion estimates represent temporal variations of the Earth's center of mass relative to the terrestrial reference frame. The dataset contains the three Cartesian components of geocenter motion (GCM_X, GCM_Y, and GCM_Z) from January 1996 to October 2024. The accompanying GPS station list includes the stations used for the geocenter motion estimation. The data are generated based on GPS displacement observations and the Optimal Sequence Estimation approach described in the related manuscript.
