How the Iridium 9555 Works | The Iridium Network Explained

The Iridium satellite network, like others, is comprised of a number of satellites orbiting the earth. The difference with Iridium is there are 66 Low Earth Orbit (LEO) satellites operating in a mesh system that means you are always within connectivity reach of at least one of Iridium’s satellites at any given time. When someone uses a satellite phone to make a call, calls are relayed from the satellite phone or data unit on the ground to one of the Iridium satellites. They are then relayed from one satellite to another then down to an appropriate ground station. The call is then transferred to the public voice network or Internet when it reaches the recipient.


Anyone in a commercial setting travelling abroad or to any isolated location in the world would benefit from taking an Iridium satellite phone with them. They will be able to stay reliably connected no matter where they are, providing much-needed peace of mind for colleagues and management back at headquarters.
