Mobile satellite communication network operator Inmarsat has confirmed the commercial service introduction (CSI) of GX5, its newest, most powerful geostationary satellite to date.

GX5 is the 14th satellite currently in service with Inmarsat and provides additional capacity on the Fleet Xpress (FX) Ka-band maritime broadband service to Europe and the Middle East. The satellite delivers about double the combined capacity of the entire existing Global Xpress (GX) fleet (GX1-GX4). This milestone heralds the start of an unprecedented enhancement in the overall capacity and capabilities of the GX network, which includes an expanded ground station network, providing what is said to be the first and only globally available high-speed mobile broadband network delivered by a single operator. Inmarsat will see a further seven launches by 2024, five in geostationary orbit - adding speed, capacity and resilience - and two in highly elliptical orbit, which will provide a mobile broadband service in the Arctic region.

Rupert Pearce, CEO 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 programme 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.”

Peter Hadinger, CTO Inmarsat, said: “Inmarsat is investing more than ever before to deliver global, highly differentiated technology platforms on which partners and customers can securely invest and 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 digitisation strategies based on Inmarsat’s innovative technology roadmap for the future.”

The services delivered over GX5 will be backwards compatible with existing GX terminals, with the benefits of GX5 becoming apparent as they are introduced in the coming weeks. Inmarsat’s ground network is expanding from 21 stations in 2019 to 30 by 2021.
