- Аннотация: First we obtain accurate analytical series representing the main part of variations of the geopotential coefficients caused by the solid Earth tides. The KSM03 expansion of the Earth tidegenerating potential is used as a source. Then we use these series in analytical calculation of the corresponding tidal perturbations in satellite motion. Two geodynamical satellites are considered: low-altitude STARLETTE and high-altitude ETALON-1. The accuracy (r.m.s. error) of analytical calculation of the discussed effect is estimated as 2 cm for STARLETTE over a time interval of 1 month (or some 415 orbits of the satellite) and 1 mm for ETALON-1 over a time interval of 1 year (or some 775 orbits of the satellite).
