Inmarsat and Honeywell launch the world’s fastest L-band in-flight connectivity service for business aviation

SwiftJet, powered by Inmarsat’s ELERA network and a modernized terminal from Honeywell, will be up to six times faster than Inmarsat’s current L-band solution for business aviation.

LONDON-(BUSINESS WIRE)-Inmarsat and Honeywell have set a new benchmark in satellite communications with the launch of SwiftJet, its latest onboard connectivity service for the aviation industry. business. This service, which will be launched commercially in the first half of 2023, will offer the fastest L-band connection speeds.

One of the first new services to be launched as part of Inmarsat’s ELERA satellite network, SwiftJet will deliver seamless global flight path coverage with a maximum connection speed of 2.6Mbps – up to six times faster than in Inmarsat’s current L-band connectivity solution used in business aviation. This will allow passengers to create a secure “in-flight office” with enhanced capabilities for video calling, web browsing, email, texting, cloud synchronization and collaboration tools such as Microsoft Teams. Social networks and video applications such as TikTok and YouTube, which have previously caused problems with the L band, will also be activated.

The latest addition to Inmarsat’s portfolio of onboard connectivity services, SwiftJet will be available on Jet ConneX (JX) and SwiftBroadband (SBB), which are already activated on thousands of aircraft worldwide. Powered by a global constellation of Ka-band satellites, JX is the most popular and widely adopted premium broadband solution available today. SBB even offers connection speeds of 432Kbps in the L-band, thanks to a smaller antenna, suitable as a secondary JX system, or primary connection in the case of older or smaller devices.

SwiftJet uses sophisticated hardware from Inmarsat’s partner, Honeywell, that can be installed on a wide range of aircraft and also supports services to ensure aircraft and cockpit security. Inmarsat’s current SBB service customers will benefit from a natural upgrade process without having to replace any externally mounted device equipment, while new customers will experience the ease of installation. install it, similar to any Inmarsat L-band terminal. This service also creates new market opportunities for small jet aircraft, which until now had to settle for basic voice or text connectivity that did not meet the needs of today’s travelers. It is available for pre-order from Honeywell, with additional incentives as part of a pioneering adoption campaign.

Inmarsat is launching this innovative service at an important time for the aviation business industry. Following the turbulent weather over the past two years due to the global pandemic, a recent survey by Inmarsat and Corporate Jet Investor (CJI) found that nearly 80% of respondents worldwide believe that the frequency of flights by business aviation will increase next year. In addition, an impressive number of them (90%) feel that online activities – divided between business and leisure – monopolize, for all leaders, the time spent on board.

Kai Tang, Head of Business Aviation at Inmarsat: “Inmarsat prides itself on providing services that meet the unique and evolving needs of its customers. Business, Inmarsat developed SwiftJet in response to feedback from customers and partner requesting a more advanced L-band offer. “.

“I’m proud to say that SwiftJet delivers all of these features, with exciting new in-cabin features that allow users to connect more devices and take advantage of faster connection speed anytime, anywhere. This launch was made at a time when business air travel was not only returning to pre -pandemic levels, but experiencing an unprecedented need for onboard connectivity. ”

Adam Sheppard, Honeywell Aerospace’s Director of Aircraft Connectivity: “SwiftJet represents the latest breakthrough in onboard connectivity. It combines Inmarsat’s commercial satellite capabilities and Honeywell’s connected aircraft efficiency to deliver flexible broadband satellite communications for passengers traveling 40,000 ft. We have created, together with The Inmarsat, a simple upgrade process for SwiftBroadband customers, making it easier for them to access previously unmatched broadband connection speeds .L, without having to change the wiring or the antenna “.

Inmarsat’s ELERA global satellite network offers the most reliable and flexible connectivity in the world, with full redundancy and exceptional stability in all conditions. ELERA’s capabilities have been further enhanced with the addition of two Inmarsat-6 satellites, the largest and most sophisticated commercial communications satellites ever produced, both of which are expected to enter service next year. They will support SwiftJet in the 2030s, which will strengthen the long -term value of the service. The L-band capacity of each I-6 satellite will be greater than Inmarsat’s 4th generation spacecraft, with 50% additional capacity per beam, in addition to unlimited beam routing flexibility.

The I-6 series of satellites will also play an important role in the continued growth of Inmarsat’s unique dynamic mesh network, ORCHESTRA, which will combine existing geosynchronous (GEO) satellites, low orbit (LEO) satellites and terrestrial 5G to develop a high-performance integrated solution that has no equivalent in the offer, whether existing or planned, of its competitors.
