Abstract

Global navigation satellite system GLONAS is widely used nowdays in many fields of science and technology. As its american analogue, Global Positioning System (GPS) it plays an important role in estimation of Earth Orientation Parameters(EOP).Asitisknonwn, EOP are confidently estimatedfrom navigation satellites observations only for frequencies from approximately one cycle per year to one cycle per day. EOP on intervals longer than one year are estimated with lower accuracy due to relatively low stability of navigation satellites orbits. At the same time, subdiurnal EOP appear to be unrealistic, most probably due to correlations between EOP and satellite orbital elements. This problem may be solved by construction of an analytical motion theory of navigation satellites. In this respect GLONASS has an advantage over GPS in the fact that motion of the former is corrected far more rarely than that of the latter. In this paper power spectra of GLON Ass satellites are ccomputed. Orbital elements are estimated from precise ephemerides of the International GNSS Service. Power spectra of the orbital elements are then estimaed by the maximum entropy method. Refs 3. Figs 5.
