Inmarsat’s SwiftBroadband successfully supports General Atomics trans-Atlantic test flight

12 July 2018: Inmarsat Government has successfully supported General Atomics Aeronautical Systems, Inc. (GA ASI) in the trans-Atlantic flight test with Inmarsat SwiftBroadband, delivering resilient, seamless, redundant connectivity throughout the duration of the journey.

The test was the first-ever transatlantic flight of a Medium Altitude, Long Endurance (MALE) Remotely Piloted Aircraft (RPA) and the GA ASI-owned MQ-9B SkyGuardian RPA flew from the company’s Flight Test and Training Center in Grand Forks, North Dakota, USA, to the Royal Air Force (RAF) Fairford base in Gloucestershire, UK.

SwiftBroadband operates over the Inmarsat-4 (I-4) satellite constellation, covering all major aviation routes worldwide. With always available global coverage, it eliminates the need for forward deployed ground infrastructure for command and control as well as take-off and landing operations, an option that is not commonly available for traditional RPA operations.

Full flexibility

During the remotely piloted flight, SwiftBroadband delivered seamless, worldwide coverage across multiple spot beams and satellites, ensuring no gaps in coverage and performance.

The service also provided full flexibility in route selection for the long endurance flight, while supporting mission-critical and time-sensitive data applications to include imagery and video. SwiftBroadband enabled full command and control of the RPA, delivering 100% control and visibility for the entire flight.

“Inmarsat is proud to have been part of this historical endeavour with General Atomics. Our history of commitment to safety services drives our global mobility-centric strategy, unique in the market. As a result, the trans-Atlantic flight test benefited from reliable and uniform worldwide seamless coverage, flexibility, resilience and security, ensuring success of the RPA’s mission,” said Kai Tang, Chief Commercial Officer, Inmarsat Government.

Unparalleled coverage

Government and commercial operations are using Inmarsat’s reliable, worldwide L-band space and ground network on multiple platforms and missions today through Inmarsat type approved antennas (as small as five inches) at unprecedented data rates (as high as 10Mbps x 10Mbps), built for manned and unmanned aeronautical platforms.

These solutions provide users unparalleled coverage and performance for their aeronautical connectivity needs, while retaining the ease of use, reliability and low cost of ownership provided by Inmarsat’s global network.
