About us

Inmarsat is the leading provider of global mobile satellite communications and has been providing connectivity on land, at sea and in the air for more than 35 years.

Set up in 1979 by the International Maritime Organisation (IMO) to enable ships to stay in touch and call for help in an emergency, our business has evolved and today our customers also include governments, media, utility companies, the oil and gas industry, humanitarian aid agencies and airlines.

What we do

Inmarsat powers voice and high-speed data communications where terrestrial telecom networks are unreliable or simply do not exist.

To ensure we provide the best connectivity solution for our customers’ needs, our business is split into five distinct Business Unit areas:

  • Maritime – thousands of vessels rely on us for operational communications and safety services at sea, from deep sea merchant vessels, coastal merchant and work boats to fishing and leisure craft
  • Enterprise – we have the largest portfolio of global voice, broadband data and machine-to-machine (M2M) services for use on land, and our markets include utilities, media, oil and gas, mining, aid and NGO, construction, banking and finance, eHealth, eLearning, and transport and logistics
  • Aviation – we provide ultimate connectivity for the whole aircraft, from cockpit to cabin, for both business and commercial aviation markets, and are the trusted provider of satellite safety services for over 90% of the world’s wide-bodied aircraft
  • Global Government – depended upon by governments in over 80 countries, we connect first responders, border control, international affairs, military operations and civil governments
  • U.S. Government – dedicated to U.S. government missions, we provide a trusted network of global mobile, mission-critical satcom services for U.S. defense, intelligence, homeland security and civilian organisations.
