Inmarsat Group – About Us

Inmarsat has been at the forefront of mobile satellite services for more than three decades and is the leading provider of global voice, data and IP communications solutions.

We deliver mission-critical communications where terrestrial networks don’t go or are ineffective.

We own and operate a fleet of 10 satellites providing seamless mobile voice and data communications around the world.

Inmarsat was founded in 1979 so ships could stay in constant touch. In 1999, we became the first intergovernmental organisation to transform into a private company and, in 2005, we floated on the London Stock Exchange.

The group expanded in 2009 with the acquisition of our distribution partner, Stratos Global, followed in the next two years by the purchase of Segovia, a provider of secure IP-based managed solutions to the US Government, and leading VSAT provider Ship Equip.

As of January 2012, after a restructure designed to bring the business closer to our partners and customers, all our businesses now use the “Inmarsat” brand name.

Together the group has unrivalled expertise in a range of cross-platform mobile and fixed satellite, microwave and wireless technologies, which enables us to offer the widest portfolio of global communications solutions and value-added services available on the market.

On land, we enable people and organisations to make calls or connect to the internet - whenever and wherever they need – using handheld satellite phones or small notebook-size broadband devices.

At sea, we offer a range of communication and safety services, including voice and broadband IP data for vessel operations, crew and passenger connectivity, and access to the Global Maritime Distress and Safety System (GMDSS).

In the air, we are the most widely used satellite operator in the aviation sector, enabling a diverse range of applications for the cockpit and cabin, from safety communications, weather and flight updates to email, internet and phone services.

For our government users, we serve their needs across all market areas, thereby fulfilling their operational needs, whether in theatre or as first responders in times of need.

With the deployment of our next-generation Inmarsat-5 (I-5) satellites from 2013, our new Global Xpress™ network will deliver superfast data and voice services at speeds of up to 50Mbps.

You can buy Inmarsat services and solutions through our worldwide network of independent distribution partners and service providers.
And now, with offices in more than 40 locations across every continent, our world-class products, services and solutions and 24/7/365 customer support facilities are also available directly from Inmarsat.
