Iridium

Has 66 active satellites in 6 orbital planes with 11 satellites in each plane. At only 780 kilometers from the Earth, the proximity of Iridium’s LEO network means pole-to-pole coverage, a shorter transmission path, stronger signals, lower latency, and shorter registration time than with GEO satellites. In space, each Iridium satellite is linked to up to four others creating a dynamic network that routes traffic among satellites to ensure global coverage, even where traditional networks are unavailable.
