Abstract
As a new constellation for global satellite communication networks applying optical inter- satellite links, a double-layered low earth orbit satellite constellation with two different altitudes is proposed. In the lower layer, several hundred satellites operating as links for user terminals are arranged. The upper layer contains several tens of satellites that relay data from the lower layer satellites to other satellites or earth-based gateway stations. The satellites deployed in the lower layer can be simplified and miniaturized, because their only function is to link small earth-based terminals and they have only three inter-satellite link terminals. The satellites in the upper layer are complex and heavy, but only a small number of them required. Orbital parameters and inter-satellite link parameters are evaluated in the constellation. Also, special features of this constellation compared with usual constellations with a single altitude are shown.
