Most powerful satellite to date, GX5, providing high-speed broadband service designed for the maritime industry by Inmarsat

Inmarsat has confirmed and activated GX5, providing additional capacity to Europe and the Middle East on the Fleet Xpress Ka-band high-speed broadband service designed for the maritime industry. To date, it is its most powerful satellite yet.

Launched in November 2019, the satellite is exceptionally efficient as it delivers approximately twice the combined capacity of the existing four GX (Global Xpress) satellites, becoming Inmarsat’s 14th operational vehicle in orbit.  Coupled with a significantly expanded ground station network and enhanced cloud-based processing, this enables GX5 to supply the global coverage of GX. As a result, it supports the rapid growth in customer demand for GX services in the region, particularly for the maritime sectors.

Rupert Pearce, CEO of Inmarsat, said: “As the world leader in global mobile satellite communications, we have an ambitious vision for the future and we are progressing the most innovative technology development program in our history to achieve this. During these recent unprecedented circumstances, we have supported our partners and customers with the speed and agility for which Inmarsat has become known globally. We are in this for the long haul, with customer and partner trust based on four-decades of meeting our commitments and a bright future ahead, guided by our technology roadmap. Entry into service of GX5 is the first of several exciting steps ahead for us on that journey.”

Inmarsat planned to launch another seven satellites by 2024, all of which are fully funded. Five will be in geostationary orbit – improving the current network by increasing speed, capacity and resilience – and two in elliptical orbit crossing over the poles, taking its place as the only commercial mobile broadband service in the Arctic region.

Peter Hadinger, Chief Technology Officer of Inmarsat, said: “Inmarsat is investing more than ever before to deliver global, highly differentiated technology platforms on which partners & customers can securely invest & innovate for growth. The company’s fully funded technology roadmap will lead to forthcoming launches for our sixth generation of satellites, the I-6s, then on to GX7, 8 & 9 and two Arctic payloads, GX10A and GX10B, to provide further fresh impetus to our GX success story. Our partners and customers can confidently invest in long-term, transformational global digitalization strategies based on Inmarsat’s innovative technology roadmap for the future.”

To date, GX is the most successful service launch by Inmarsat. The company plans to celebrate the fifth anniversary of GX by positioning it as a globally-available service in early 2021. It has already become the gold standard for seamless, mobile broadband services across multiple sectors. Many of the active users came from industries such as aviation, maritime, enterprise and government.
