West Star Aviation has launched a supplemental type certificate (STC) program for installation of Gogo Business Aviation’s Galileo satcom system in Embraer Legacy 450/500s, Praetor 500/600s, and ERJ-135/145s, the latter of which includes Legacy 600/650s. The company expects to complete these STCs early next year.

The West Star STC will be for installation of the Gogo Galileo HDX (half-duplex) antenna, which provides airborne connectivity speeds of 43 to 60 Mbps. For aircraft already equipped with Gogo Avance L5 air-to-ground (ATG) systems, upgrading to Galileo HDX is retail priced at $120,000, plus installation. Service costs for unlimited data range from $11,500 per month with ATG or $10,500 for Galileo alone.

The Galileo service runs on Eutelsat’s OneWeb low-earth-orbit satellite network, which provides global satcom service. Gogo expects to launch the service by year-end.

“As the demand for seamless connectivity in aviation continues to grow, we are excited to offer these three new STC solutions for the Embraer Legacy and Praetor aircraft,” said West Star Aviation sales director Marty Rhine.
