Abstract

A non-uniform planar spaced constellation of satellites for providing continuous global or regional coverage including at least one pair of orbital planes having inclined co-rotating orbits, and at least one other orbital plane immediately adjacent one orbital plane of the pair of orbital planes having an inclined counter-rotating orbit, and wherein the fields of view of the satellites in the one pair of co-rotating orbital planes form an overlapped array of hexagonal packing at the equator, and the field of view of the satellites in the one other counter-rotating orbital plane and the one co-rotating orbital plane of the pair of co-rotating orbits form an overlapped array of rectangular packing at the equator, and wherein the spacing between the pair of co-rotating orbital planes is greater than the spacing between the one other counter-rotating orbital plane and the one co-rotating orbital plane.
