Part of the Iridium NEXT constellation's 86.4°-inclined polar orbit, ensuring genuinely global coverage including the extreme polar latitudes most competing satellite networks cannot reach. This satellite contributes to a mesh network design that lets Iridium maintain connectivity even during major ground infrastructure outages, since calls can route satellite-to-satellite around any affected region.
