NUMERICAL SOLUTION OF SATELLITE MOTION UNDER THE EFFECTS OF THE EARTH’S GRAVITY OF THE AXIAL SYMMETRY AND DRAG FORCE IN TERMS OF THE KS-REGULARIZED VARIABLES

This paper is concerned with an orbit prediction using one of the best regular theories (KS-regularized variables). Perturbations due to the Earth’s gravitational field with axial symmetry up to the fourth order zonal harmonic and rotating/non-rotating atmosphere (variation in density model with height) are considered. Applications of the problem will be illustrated by numerical and graphical example.
