Perturbation effect on ground tracks of Molniya satellite orbits

The main concern in the present research work is to define the basic requirements study of manyperturbations forces that affect ground tracks of Molniya satellite orbits.In this we are going to design a mathematical model to calculate the footprint of any satellite takinginto account the effect of disturbing forces (oblatness and solar radiation pressure) in order to get themost accurate sub-satellite point, matlab language is used to design program to calculate themathematical models of footprint satellites with numerical application of some different Molniyasatellites orbit.
