Gulfstream works with Honeywell to certify JetWave X for business jets

The partnership aims to equip GIV, GV, G450, G500, G550, G600, G650 and G700 aircraft with high-speed, reliable connectivity for passengers and crew.

Honeywell’s JetWave X system brought ultra-fast in-flight connectivity designed to mirror home and office experiences, with compatibility across Viasat’s GX and Viasat satellites. The system will also support future modem architectures and new satellite networks, including ViaSat-3 Ka-band.

“Business jet operators are looking for globally consistent, high-network capacities for passengers to stay truly connected,” says Jason Wissink, president, services and connectivity, Honeywell Aerospace Technologies. “With JetWave X, users will be able to easily connect Viasat’s existing GX and Viasat satellites, and the system will enable them to add additional modem architectures in the future to provide access to new satellite networks – such as the ViaSat-3 Ka-band satellite network – as they become available. For OEMs and MROs, a simplified product architecture will not only make the system easier and faster to install than the current-generation JetWave system, but it will also offer an economical upgrade path for existing JetWave customers.”

JetWave X will continue to be supported by Honeywell’s around-the-clock white glove service, with most aircraft platforms expected to receive certification in the first half of 2026. JetWave systems have been among the most widely adopted connectivity solutions for long-range aircraft since their 2017 debut, and Honeywell will continue to support the existing generation, which may see enhanced performance through JetXP in-flight plans.
