Van Nuys, California-based Thornton Aviation has accomplished its first Gogo Galileo HDX low-earth-orbit satcom installation, on a customer Gulfstream G200 that was upgraded from Gogo’s classic air-to-ground (ATG) system. Thornton Aviation used Trimec Aviation’s supplemental type certificate for the upgrade.
The three-week job replaced the classic ATG with Gogo’s Avance L3 Wi-Fi system with the HDX satcom terminal, including the antenna mounted on top of the fuselage. Gogo Galileo uses the Eutelsat OneWeb low-earth-orbit satellite network, which provides high-speed, low-latency airborne connectivity worldwide, except in countries that prohibit satellite communications.
“The customer took advantage of Gogo’s ATG to Avance L3 promotion, which added value to their upgrade,” said Don Milum, Thornton Aviation’s chief revenue officer. “Additionally, the benefits of Eutelsat’s OneWeb low-earth-orbit satellite network further enhances onboard connectivity and operational capabilities.”
Gogo’s classic ATG service will be switched off in May 2026, and customers with the older system can upgrade to a replacement that will enable continued use of the ATG network or plan on upgrading to the faster Gogo 5G ATG or Galileo satcom. Gogo 5G is expected to go live by year-end.
