It begins in May of 2000 with a 1.5 billion dollar international investment program making the way for the Inmarsat I-4 program. Each satellite is equipped with a nine meter wide reflector and forty-five meter solar arrays.
In March 2005 the first I-4 satellite is launched from Cape Canaveral propelled by the Atlas five rocket. The I-4 satellites are sixty times more powerful than their redecessors. The I-4 satellites are the most advanced satellites ever launched.
In November 2005 on a converted oil platform in the Pacific Ocean a second I-4 satellite was successfully launched giving Inmarsat 85% coverage of the earth's landmass and 98% of the world's population, but Inmarsat is not done.
Inmarsat's goal is to bring the ultimate in mobile satellite communication. Inmarsat is delivering broadband data and voice communication to almost anywhere on the planet on land, sea or in air.
In August 2008 in Kazakh where the space race began 51 years ago the third and final I-4 satellite is successfully launched. With all three I-4 satellites fully operational, Inmarsat is providing seamless broadband satellite communication globally.
The I-4 constellation performs 20,000 system checks every 20 seconds bringing reliability and performance to the core of the I-4 system. The I-4 has a life span of 20 years allowing Inmarsat to maintain its status as industry leader in satellite communication.
With a solid 30 year history in the satellite communication industry Inmarsat really is "The mobile satellite company".
