ACJ customers are one step closer to ultra-fast in-flight connectivity now that EASA has STC certified Airbus’ ACJ320/320neo aircraft with the latest generation high-speed Gogo Galileo “Full-Duplex” (FDX) integrated solution.
Certified on May 11th, the FDX installation includes a new electronically steerable flat antenna (ESA).
This ESA is a core part of Airbus’ “ACJ Connect” connectivity platform, which was developed with Gogo and utilises Eutelsat OneWeb’s Low Earth Orbit (LEO) constellation, and was first announced in February 2025.
The FDX certification milestone builds on Airbus’ introduction last year of Gogo Galileo’s “Half Duplex” (HDX) solution on the ACJ319 Family.
While HDX offers up to 60 Mbps download and 11 Mbps upload capability, Gogo’s FDX option for the larger ACJ320 offers up to 195 Mbps download and 32 Mbps upload.
ACJs equipped with either the FDX or HDX systems will be harnessed into Eutelsat OneWeb’s Low Earth Orbit (LEO) constellation of more than 640 satellites.
The LEO-based network satellites orbit much closer to the earth, offering higher speed and lower latency, combined with global coverage, even at the poles.
Chadi Saade, President of Airbus Corporate Jets, said: “We are delighted to be among the first corporate aircraft manufacturers to offer and support a certified, fully integrated LEO in-flight connectivity solution, leveraging our partners’ respective technologies and satellite infrastructure – including Gogo Galileo’s state-of-the-art FDX antenna and Eutelsat’s OneWeb satellite constellation.”
“Achieving this certification for Gogo’s FDX offers our ACJ Connect customers a new low-latency high-bandwidth choice and consolidates the ACJ320 Family’s position as offering industry leading-business aviation connectivity.”
Michael Skov Christensen, Gogo Chief Commercial Officer, said: “The addition of the Gogo Galileo FDX gives ACJ’s customers the certainty of reliable, high-speed connectivity throughout all phases of flight, wherever they are flying.
“In addition, Gogo is proud of its commitment to data privacy and cybersecurity. We only use customer data for operations and never for any other purpose, including the development of other products or artificial intelligence – something to reassure ACJ’s customers.”
Compared with the HDX solution, FDX features a larger full-duplex ESA antenna with two arrays: one for data transmission and one for receiving, enabling even higher-speed, low-latency connectivity for the cabin.
Meanwhile, the HDX option comprises a single electronically steered array that constantly and seamlessly switches between transmit and receive modes, enabling the transfer of data to and from a satellite.
