Generalized mean of individual EOP series by least-squares collocation technique
Abstract
To obtain combined solution of the Earth orientation parameters,least-squares collocation method is used. Auto- and crosscovariance functions of signals were calculated. The result corrections achieve ± 0.25~mas of arc for polar motion and nutation, and ± 0.02~ms for UT1-UTC.
