Abstract
In this paper, we study the GPS orbit as an orbit for navigational satellites; we are concerned with analyzing and simulating the EFFECT OF EARTH’S OBLATNESS, which gives an image for what a satellite will suffer due to this perturbing force. Finally, a numerical technique is used to calculate a real GPS satellite as an example.
