A model experimental investigation of the accuracy of ground station coordinates, determined by Doppler satellite observations is made, depending on the number of passes, satellite altitude, orbit inclination, frequency of Doppler transmitter, intervals of Doppler counts, etc. Using satellite pases at altitudes of 1000, 3000 a 5000 km, optimization of the Doppler observations is also achieved.
(Summary) Using published results of the international centres BIH IPMS and some publications by a number of authors in connection with the investigation of the Earth rotation irregularities, the present work treats some comparisons and analyses of the qualities of the classical and space methods for determining the Earth rotation irregularities underlining our point of view concerning the use of methods in the process of research.
