Gogo Business Aviation’s Galileo HDX electronically steerable antenna (ESA), designed to provide access to Low Earth Orbit (LEO) satellite networks for all sizes of business aircraft, has passed FAA-mandated DO-160 qualification testing.

“Passing DO-160 keeps us on track to receive the first-article STC and commercially launch Gogo Galileo later this year,” says Jeremy Tyler, vice president of airborne product engineering.

DO-160 testing ensures the Gogo Galileo HDX antenna is safe for use in the harsh environmental conditions encountered in flight, including temperature volatility, intense vibration, radio wave penetration, lightning strike, moisture penetration and flight aerodynamics.

Gogo developed the HDX, capable of peak speeds approaching 60Mbps, in partnership with Hughes Network Systems, an EchoStar company. In the second quarter of 2025, Gogo plans to deliver Gogo Galileo FDX for larger aircraft, capable of peak speeds approaching 200Mbps.

Gogo dealers are receiving unprecedented demand for Galileo HDX and have contracted to complete 27 STCs covering a total addressable market of more than 18,000 aircraft globally.

Gogo Galileo will connect to the enterprise-grade Eutelsat OneWeb LEO satellite network, which is designed for mobility to deliver consistent performance with low variability across all routes around the Globe.

Gogo is accepting purchase orders for the HDX, which is designed to be a faster and lower-cost upgrade to any Avance system (Avance L3, L5, LX5, SCS) than installing a new competitive ESA LEO system.
