INMARSAT

Inmarsat is the world's leading provider of global mobile satellite communications. The system provides voice and high-speed data services to almost anywhere on the planet — on land, at sea and in the air. The services are delivered through the most versatile and reliable satellite network in the world. Inmarsat has stood at the forefront of mobile satellite services for nearly 30 years.

While continuing to perform its original mandate, Inmarsat has since expanded into land, mobile and aeronautical communications, so that users now include thousands of people who live or work in remote areas without reliable terrestrial networks, or travellers anywhere.

Users such as national emergency and civil defence agencies, emergency ministries, power structures and public institutions, transport companies, health teams, journalists and operators, alpinists and lovers of extreme types of sport.

Inmarsat covers about 98% of the land mass area.

Each satellite covers up to one third of the Earth's surface and is strategically positioned above one of the four ocean regions to form a continuous 'world-wide web in the sky'. Every time a call is made from an Inmarsat mobile satphone it is beamed up to one of the satellites. On the ground, distributed all around the world, giant communications antennas are listening for the return signal, which they then route into the ordinary telephone network. And when someone calls an Inmarsat customer, it happens the same way — but in reverse
