    On the third-body perturbations of high-altitude orbits

    The long-term effects of a distant third-body on a massless satellite that is orbiting an oblate body are studied for a high order expansion of the third-body disturbing function. This high order may be requir...

    PPKBZ9 \(\mathcal{A}, \mathcal{S}\mathcal{A}\) Two Orbit Propagators Based on an Analytical Theory

    In the context of general perturbation theories, we analyze the motion of an artificial satellite around an Earth-like planet perturbed by the first eight zonal harmonic coefficients. By means of two Lie trans...
