Inmarsats coverage around the globe.
The Inmarsat network uses three geostationary satellites to provide voice and data communication services almost anywhere in the world. Each satellite is equipped with a single global beam that covers up to one-third of the Earth's surface. Because Inmarsat coverage extends from latitudes of -82° to 82° regardless of longitude, higher latitudes will have lower performance. Registration to the network requires a clear line of sight to the equator and may not be suitable for use in canyons or mountains.
The map below depicts the three I-4 satellite coverage regions.
