Iridium GO! - Using Iridium GO! and Your Smartphone

Iridium GO! User Manual 33
5
Iridium GO! requires connection to the Iridium Satellite Network. The swivel antenna should be
vertical to the ground and have a clear unobstructed view of the sky. For optimal performance,
the antenna must be able to “see” the entire sky from approximately 8 degrees above the horizon.
Nearby tall buildings or similar structures, heavily leafed trees and mountains can all degrade
performance as they block the signal between the antenna and the satellites. Having a completely
open view of the sky plays a very important role in maximizing performance, as the Iridium satellites
move across the sky from North horizon to South horizon during a connected call.
