Inmarsats

Inmarsat is a British satellite communications company that provides global mobile connectivity through a fleet of geostationary satellites and a worldwide network of ground infrastructure. The company traces its origins to the International Maritime Satellite Organization (INMARSAT), an intergovernmental treaty-based organization established in 1979 to ensure reliable communications for maritime safety and commerce. It later transitioned from an international organization to a private company and has since become a leading provider of satellite-based communications for maritime, aviation, government, and enterprise customers.

The satellite fleet includes the Inmarsat-4 family, which forms the backbone of its global coverage, the Alphasat program developed with international partners, and the Global Xpress (GX) network, a high-throughput Ka-band system designed to deliver fast, secure broadband connectivity for users at sea, in the air, and on land.

Inmarsat delivers a range of services, including voice and data communications, broadband for ships and aircraft, and secure government communications. Safety services, including maritime distress and safety communications, are supported through L-band infrastructure as part of the GMDSS framework. The company serves maritime operators, airlines, government agencies, and other enterprises that require reliable connectivity in remote or challenging environments.

Headquartered in London, Inmarsat operates globally through its commercial and government business units, supported by partnerships with equipment manufacturers, ground network operators, and regional service centers. The company maintains an emphasis on reliability, security, and global reach across its service offerings.
