Inmarsat, a leading provider of global mobile satellite communications services, has announced that the third satellite in the transformational Global Xpress (GX) programme – Inmarsat-5 F3 (I-5 F3) – has been scheduled for launch at the Baikonur Cosmodrome in Kazakhstan at 12.44pm (BST) on Friday 28th August.

I-5 F3 will cover the Pacific Ocean Region and together with Inmarsat-5 F1 and Inmarsat-5 F2 will create the world’s first globally available, high-speed mobile broadband service, delivered through a single provider.


Global Xpress will deliver broadband speeds around 100 times faster than the company’s fourth generation (I-4) constellation. It will significantly enhance client’s connectivity and ass well as the access to bandwidth-hungry applications, even in the remotest and most inaccessible regions of the world.


Rupert Pearce, CEO of Inmarsat, comments: “We believe that our GX technology will drive innovation and support value-added services and solutions for our government and enterprise customers on land, at sea and in the air; in opportunities as diverse as the merchant maritime, business and commercial aviation, government, energy & resources and enterprise VSAT segments.”


Inmarsat’s 5th generation satellites have all been built by Boeing Satellite Systems International Inc. in California. The launch is being undertaken for Inmarsat by International Launch Services using a Proton launch vehicle.


The first Global Xpress satellite – Inmarsat-5 F1 – was launched in December 2013 and entered commercial service in July 2014, covering Europe, the Middle East, Africa and Asia. This was followed by the launch of Inmarsat-5 F2 on 1st February 2015, which covers the Americas and the Atlantic Ocean and which will enter commercial service later this month.


Following the successful launch of I-5 F3, Inmarsat expects to commence global commercial GX services by the end of the year.
