Inmarsat announces trans-atlantic ‘stepping stone’ trip for latest British satellite

Inmarsat, the world leader in global, mobile satellite communications, has agreed with Airbus Defence and Space to deliver its I-6 F2 satellite via a series of ‘stepping stones’ across the Atlantic using Airbus’ A300-600ST (Super Transporter).

The aircraft is better known as Beluga, thanks to its striking similarity with the species of whale.

The journey will see the satellite leave its testing facility in Toulouse and make several stops for refuelling before reaching the Kennedy Space Centre in Florida. Spacecraft experts will then have approximately three weeks for final testing and integration of spacecraft with the rocket before I-6 F2 launches on a SpaceX Falcon 9 in February.

Inmarsat’s two I-6 satellites (the first was launched in December 2021) are the most sophisticated commercial communications satellites ever built. They will provide communications coverage for more than 15 years from their geostationary orbit: 36,000km above the Equator.

I-6 F2 is a dual-payload satellite, which means it can transmit signals in both Inmarsat’s L-band and Ka-band frequencies. It is the next step in the company’s revolutionary network of the future, ORCHESTRA, which will vastly upgrade its global connectivity services. ORCHESTRA will deliver increased capacity and faster speeds by creating a ‘network of networks’: integrating Inmarsat’s ELERA (L-band) and Global Xpress (Ka-band) networks with terrestrial 5G and targeted low earth orbit (LEO) satellites, to power global mobility in the future.

It will be only the second time that Airbus will transport a satellite to Florida this way since launching its new Airbus Beluga Transport service in early 2022. Inmarsat previously used the Antonov-124 freight aircraft to deliver I-6 F2’s twin, I-6 F1, to its launch site in Japan with Mitsubishi Heavy Industries last year.

Rajeev Suri, CEO, Inmarsat, said “Building, testing, and launching a satellite is complex enough and I want to thank our talented experts at Inmarsat and Airbus, who have tackled the new transportation challenges faced by I-6 F2.”

“This launch is another step on our journey in delivering the world’s first multi-dimensional network, Inmarsat ORCHESTRA. It will build on our existing space-based capabilities to allow us to provide a transformational growth in capacity and new features for our customers into the 2030s and beyond. That means it will be able to power emerging use cases like autonomous vehicles or flying taxis, for example, as we build a better, smarter, more connected world.”

Francois Gaullier, Head of Telecom Satellites at Airbus said “We are delighted to deliver the second I-6 satellite using the Airbus Beluga service for our long-term London based customer, Inmarsat. This state-of-the-art multi-band satellite, again showing Europe is a leader in space innovation, will soon join its twin in orbit offering best-in-class capability to enable Inmarsat to provide services on a global scale.”

Inmarsat delivers world leading, innovative, advanced and exceptionally reliable global, mobile communications across the world – in the air, at sea and on land – that are enabling a new generation of commercial, governmentand mission-critical services. Inmarsat is powering the digitalisation of the maritime industry, making operations more efficient and safer than ever before. It is driving a new era of inflight passenger services for aviation, while ensuring that aircraft can fly with maximum efficiency and safety. Furthermore, Inmarsat is enabling the rapid expansion of the Internet of Things (IoT) and enabling the next wave of world-changing technologies that will underpin the connected society and help build a sustainable future. And now Inmarsat is developing the first-of-its-kind, multi-dimensional communications network of the future, ORCHESTRA.

In November 2021, Inmarsat and Viasat announced the planned combination of the two companies, to create a new leader in global communications.

The flight-plan and exact times to transport Inmarsat’s I-6 F2 spacecraft via Airbus A300-600ST (Super Transporter) aircraft are subject to changes due to weather and other operational circumstances.
