Based on Hughes Network Systems’ ESA hardware, the HDX kit can fit “on any size business aircraft” with mean speeds of 57 Mbps and peak speeds up to 60 Mbps, notes Gogo. A larger full-duplex FDX antenna designed for larger aircraft and capable of higher speeds will be available in the first half of 2025.

Gogo CEO Oakleigh Thorne previously expected flight-testing of Galileo HDX to begin in August. But the firm had to first address a faulty FADEC (full authority digital engine control) on one of the engines of the Challenger 300. Now flight-testing aboard the jet has commenced, and Gogo plans to test the IFC system “in extreme conditions in the northern polar region and then along some equatorial routes,” the company tells Runway Girl Network.

Everything remains on track to receive certification and launch later this year.

Gogo’s implementation sees the firm offering Galileo both in standalone form as a satcom-only solution and in a hybrid version that includes its air-to-ground (ATG) connectivity service for North American operators.

If the company can be locked and loaded with a supplemental type certificate for Galileo HDX on the Challenger 300 before January 1 go-live date for Eutelsat OneWeb LEO, that would be a celebrated feat indeed.

There is growing excitement around the imminent launch of Eutelsat OneWeb LEO service in civil aviation, though fully global coverage is not expected until ground network buildout is completed in spring 2025.

“Gogo Galileo customers will experience highly reliable service on the Eutelsat OneWeb enterprise grade LEO satellite network, which unlike competitive LEO networks does not share bandwidth with consumer users,” says Gogo president and chief operating officer Sergio Aguirre in apparent reference to SpaceX’s Ku-band LEO-based Starlink service.

Unlike Eutelsat OneWeb which has taken a B2B approach SpaceX is serving civil aviation market directly its Starlink Aviation solution has made some notable wins but it’s also supporting connectivity for residential users including rural locations
