Another milestone for Gogo Galileo HDX and global inflight connectivity.

AVMATS is proud to install Gogo Galileo systems, helping Gulfstream and other business aviation operators stay connected wherever they fly.

Another major milestone for Gogo Galileo HDX! ✈️🇲🇽

We are proud to share that Pentastar Aviation has secured Supplemental Type Certificate (STC) approval from Mexico's Agencia Federal de Aviación Civil (AFAC) for the Gogo Galileo HDX system on the Gulfstream G550.

Through Pentastar’s leadership as the STC holder, Gulfstream G550 operators across Mexico can now equip their aircraft with global, low-latency low-Earth-orbit (LEO) satellite connectivity.

Key benefits of the Pentastar STC update:

Global Eutelsat OneWeb LEO Performance: Low-latency broadband for video calls, live streaming, and heavy cloud applications anywhere in the world.

Expanded Regional Coverage: Adds AFAC validation alongside FAA and TCCA approvals, broadening global fleet readiness.

A huge thanks to the team at Pentastar Aviation for driving this certification across the finish line!
