A SEMI-ANALYTICAL METHOD OF COMPUTATION OF OCEANIC TIDAL PERTURBATIONS IN THE MOTION OF ARTIFICIAL SATELLITES

摘要

In the present article we discuss the method of expansion of the satellite's perturbations, as caused by the oceanic tides, into Fourier series with the arguments Ω and π of the satellite and l, l' F, D and p of the Moon. The coef¬ficients in this expansion are purely numerical and peculiar to each particular satellite. Such a method is termed as semi-analytical in Celestial Mechanics. Gaussian form of the differential equations for variation of elements, with the right hand sides averaged over the orbit of the satellite, is convenient to use with the semi-analytical expansion.
