Inmarsat Coverage Map

inmarsat coverage map

Inmarsat has been an industry leader in satellite communications since 1976. Offering near-global connectivity everywhere on the planet, with the exception of the Polar Regions, Inmarsat solutions have been engineered to withstand harsh conditions while still providing high-quality coverage whether on land, at sea or in the sky.

Inmarsat attains near-global network coverage for voice and data communications using its 3 geostationary (GEO) satellites. Each satellite is equipped with a single spot beam that covers up to one-third of Earth’s surface. Beams cover oceans and land masses to keep users connected even in the harshest conditions.

To connect to the Inmarsat network, your device antenna will require a clear line of sight to the sky towards the equator. They are best used when stationary and are less suited for users on the move. It is important to note that registration may take a little longer to connect than competing networks, as Inmarsat satellites orbit further away from the earth (approx. 22,000 miles away). Inmarsat service may be limited at the edge of coverage areas, or may fluctuate depending on conditions or location such as mountainous terrains where there is no direct view to the equator.

How does it work?

Near-global coverage is provided via the Inmarsat satellite constellation that orbits approximately 22,000 miles above the earth. The constellation consists of 13 satellites in geosynchronous (GEO) orbit that are positioned to transmit radio beams covering the earth’s oceans and land masses.

Inmarsat coverage extends to parts of the world from latitudes of -82° to 82° regardless of longitude, meaning higher latitudes such as the Polar Regions are excluded.
