Abstract:

This report presents a first-order discussion of the perturbations in the orbital motion of a satellite about an oblate primary. The approach is non-traditional in that the secular changes in the semi-major axis, eccentricity, inclination, and longitude of the ascending node are all derived directly from the translational and rotational equations of motion. The exactly solvable problem of motion in the primarys equatorial plane is used to obtain the advance of the argument of periastron the consequent change in the time of periastron passage. In addition, a simple discussion of a very restricted three-body problem is given to illustrate of the effects of third-body perturbations. Author
