A satellite is expected to move in the orbit until its life is over. This would have been true if the earth was
a true sphere and gravity was the only force acting on the satellite. However, a satellite is deviated from its normal path due to several forces. This deviation is termed as orbital perturbation. The perturbation can be generated due to many known and unknown sources such as Sun and Moon, Solar pressure, etc. This paper discusses the study of perturbation of a Low Earth satellite orbit due to the presence of aerodynamic drag. Numerical method (Runge – Kutta fourth order) is used to solve the Cowell’s equation of perturbation, which consists of ordinary differential equation.
