Fundamental earth orientation parameters in determining the accuracy of the long-term ephemeris-time corrections in satellite navigation

摘要

A few-parameter numerical-analytical model for the rotational-oscillatory motions of the Earth is used on long time intervals in the processing of the highly accurate measurements of the topocentric distances to the Etalon-1 and Etalon-2 artificial Earth satellites. A proposed model can be used in satellite navigation algorithms.
