Elliptical Lunar Frozen Orbit

Five relays, one per polar plane, ascending nodes 72° apart — each holds apolune over the south pole. Drag to look around.

Illustrative Kepler model: five satellites, one per polar plane (inclination 90°, ascending nodes 72° apart), each holding apolune over the south pole and phased 72° apart so they hand the pole off in turn. Every plane passes directly over the pole; RAAN only rotates the rest of the ground track. Real position from a two-body solve; line-of-sight from a true horizon test. No perturbations, terrain masking or link-margin cutoff — a diagram, not a propagation.
