Analytical theory for highly elliptical orbits including time-dependent perturbations
Guillaume Lion, Gilles Métris
Traditional analytical theories of celestial mechanics are not well-adapted when dealing with highly elliptical orbits. On the one hand, analytical solutions are quite generally ex…

Towards an analytical theory of the third-body problem for highly elliptical orbits
Guillaume Lion, Gilles Métris, Florent Deleflie
When dealing with satellites orbiting a central body on a highly elliptical orbit, it is necessary to consider the effect of gravitational perturbations due to external bodies. Ind…
