ATMOSPHERIC DRAG PERTURBATION EFFECT ON THE SATELLITES ORBITS

: In this paper the drag perturbation for the law orbit are studded ,Koll-method is suitable to used hear, equation of motion it's solved by numerical integration ;Rang-Kota-method was used ; to find the components of velocity and position and find the orbital parameters with perturbation .Study the effect of drag perturbation on the position , of satellite with time and on perigee , apogee , a ,e and age of satellite, Study the variation of satellite position and age with height we can increase the age of satellite to 40 times by increase the perigee height only 2 times, and by decrease A/m ratio and eccentricity also by rotate in the direction of the earth rotate.
