The US Federal Communications Commission (FCC) has granted regulatory approval for the Gogo Galileo HDX and FDX antenna terminals for business aircraft.

The FCC Earth station in motion (ESIM) regulatory licence grants Gogo the authority to commercialise and operate the terminals, which are integral to its Gogo Galileo low Earth orbit (LEO) global broadband service, on US-registered aircraft and those registered in other countries within US territory, including territorial waters.

"Receiving the ESIM licence for the HDX and FDX terminals represents an important milestone in bringing the Gogo Galileo service to market by year end," says Crystal Gordon, executive vice president, general counsel and corporate secretary for Gogo. "This regulatory milestone also paves the way for additional regulatory authorisations in other countries."

Gogo expects to begin flight testing the HDX terminal this summer after it is installed on Gogo's Challenger 300 testbed. The HDX terminal remains on track to receive certification and commercially launch later this year.
