The Iridium® Advantage
When a vessel is in rolling seas and driving rain, its crew should not need to worry about its satellite connection. Fortunately, the Iridium® network is designed to work in the most extreme conditions at sea.
The Iridium network design is unique: 66 cross-linked satellites in Low Earth Orbit (LEO) cover the entire globe, pole-to-pole and every point in between, all day, every day. LEO provides a stronger signal and better “look angles” than geostationary satellites, so ships stay connected, even in adverse weather and in any location – including in harbors and beyond the 70th parallels.
The L-Band frequencies Iridium uses (between 1 and 2 GHz) are different. They are less susceptible to rain fade than higher frequencies do, and they don’t require a large dish pointed directly at a satellite – both critical requirements in storms and heavy seas.
