Part of the Iridium NEXT constellation, providing the satellite phone connectivity that ship captains, polar researchers, and remote expedition teams have relied on for decades. Iridium's mesh network architecture — satellites relaying calls to each other rather than requiring direct ground station contact — makes it uniquely resilient compared to bent-pipe satellite systems that fail without ground infrastructure nearby.
