Long-Term Prediction Model of Earth Rotation Parameters for Solving the Satellite Navigation Problem
Model calculations of Earth rotation parameters in long time intervals for testing high-precision measurements of distances to topocentric artificial satellites Etalon-1 and Etalon-2, based on the model of the uneven rotation of the Earth, taking into account the mean-square estimates of an each parameter model are presented. It is noted that in the process of filtering observations measured parameters are topocentric distances, the first derivatives of the parameters which the Earth's rotation in the linear approximation can determine the covariance matrix and a priori to estimate of the residual variations due to errors in the parameters of the Earth's rotation.
