Inmarsat is the world's leading provider of global mobile satellite communications. Providing mobile voice and high-speed data services to almost anywhere on the planet - on land, at sea and in the air. 

About

Inmarsat's goal is to remain in the vanguard of mobile satellite service delivery - through a combination of extensive portfolio, global coverage and technological innovation. They also aim to deliver the highest standards of reliability in the market, while offering excellent value for money.

The launch of Inmarsat-4 satellites in 2005 - with their significantly enhanced power and capacity - has laid the foundations for the further evolution of services.

Inmarsat has stood at the forefront of mobile satellite services for nearly 30 years. They are internationally recognized as pioneers in their field and continue to introduce new technologies that redefine the standard for our industry.

The new Broadband Global Area Network (BGAN) service, for example, is now enabling TV broadcasters to beam breaking news 'live via videophone' into millions of homes.
And in future, when you make a mobile phone call or send a text message from an aircraft, most likely it will be transmitted via Inmarsat satellites to the ground.

Inmarsat network

Services are delivered through the most versatile and reliable satellite network in the world.

Inmarsat owns and operates the world's most advanced fleet of commercial mobile communications spacecraft, flying in geostationary orbit, 35,786 km (22,240 statute miles) above the Earth.

This includes our two latest generation satellites, the Inmarsat-4s (I-4s), which were launched in 2005. Together, they provide coverage to around 85 per cent of the world's landmass and 98 per cent of the world's population.

Inmarsat is also planning the launch of a third I-4 satellite. This will deliver complete mobile broadband coverage of the planet, except for the extreme polar regions.

Spot beam technology

Inmarsat's first wholly owned satellites, the Inmarsat-2s, were launched in the early 1990s, and the Inmarsat-3s - the first generation to use spot beam technology - followed later in the decade.

The total fleet now comprises 10 satellites. The I-4s set a new benchmark for mobile satellite communications in terms of their power, capacity and flexibility. One I-4 satellite is 60 times more powerful than an Inmarsat-3, and the I-4 fleet is expected to have a commercial life until around 2020.

Global voice and broadband data

Land-based customers already enjoy the benefits of our Broadband Global Area Network service - BGAN - offering global voice and high-speed data connectivity via terminals about the size of a notebook PC.

In 2007, this capability will be extended to maritime and aeronautical customers with the launch of the FleetBroadband and SwiftBroadband services - further realizing our vision of Broadband for a mobile planet™.

Inmarsat recently reinforced its leadership of the industry with our entry into the satellite phone services market. The process has begun of  rolling out the service, eventually on a global basis, over the Inmarsat-4 satellites - offering a one-stop shop for mobile satellite services.
