Pilatus PC-24 Adds Gogo Galileo LEO Broadband Connectivity
Pilatus Aircraft offers Gogo Galileo LEO internet on the PC-24 with FAA and EASA certification for new builds and retrofits.

Pilatus Aircraft has introduced Gogo Galileo high-speed internet as a factory-installed option for the Pilatus PC-24, bringing low-latency broadband connectivity to the light jet platform.
In a press release issued on July 1, 2026, the manufacturers confirmed the integration utilizes the Eutelsat OneWeb Low Earth Orbit (LEO) satellite network to provide global coverage capable of supporting video conferencing, media streaming, and cloud-based services. The system has received certification from both the Federal Aviation Administration (FAA) and the European Union Aviation Safety Agency (EASA), making it available for new production aircraft as well as retrofits for the in-service fleet.
Lufthansa Technik entertainment integration and cabin upgrades
Alongside the connectivity upgrade, Pilatus detailed a new integrated cabin management and entertainment system developed in partnership with Lufthansa Technik. The system features a 10-inch touchscreen display that allows passengers to control cabin functions and access media directly from their seats.
The audio experience has also been upgraded as part of the new package. The configuration includes four cabin loudspeakers paired with a subwoofer. To maximize cabin comfort and flexibility, Pilatus introduced a side-facing divan option measuring nearly 2 meters in length, expanding the seating and resting configurations available to PC-24 operators.
Expanding LEO connectivity across the Pilatus fleet
The PC-24 announcement follows recent connectivity advancements for the manufacturer’s turboprop line. On June 16, 2026, SD Government and Pro Star Aviation secured an FAA Supplemental Type Certificate (STC) for the installation of the Gogo Galileo HDX system on the Pilatus PC-12.
This earlier approval marked the first LEO satellite connectivity option for the single-engine PC-12. The sequential rollout indicates a broader push to equip the Pilatus product line with modern, high-speed satellite internet capabilities regardless of aircraft class.
AirPro News analysis
We view the integration of LEO satellite networks like Eutelsat OneWeb into light jets and turboprops as a critical shift in business aviation expectations. Historically, high-speed, low-latency internet was restricted to midsize and large-cabin business jets due to the size, weight, and power requirements of traditional geostationary satellite antennas. The smaller form factor of Gogo Galileo hardware allows manufacturers like Pilatus to offer heavy-jet connectivity standards on platforms like the PC-24 and PC-12 without compromising payload or aerodynamic efficiency. As LEO networks mature, factory-installed broadband is rapidly transitioning from a premium upgrade to a baseline requirement for new business aircraft.

FAA Awards L3Harris Contract to Modernize US Airspace Through 2045
The FAA awarded L3Harris a contract to upgrade 700+ ground stations and operate the US aircraft tracking network through 2045.

On July 1, 2026, the Federal Aviation Administration (FAA) awarded L3Harris Technologies a contract to upgrade and operate the United States aircraft tracking network through 2045. The modernization effort will overhaul ground infrastructure to support the integration of advanced air mobility (AAM) vehicles and drones into the National Airspace System.
In a press release issued on July 1, 2026, L3Harris announced the agreement, which mandates the upgrade of at least 700 ground stations across the country. The enhanced network will provide real-time, satellite-based flight positioning data while bolstering cybersecurity measures to protect air traffic management systems. The exact monetary value of the contract was not disclosed.
Expanding surveillance for next-generation airspace
The contract extends the role of L3Harris in managing the FAA surveillance infrastructure for nearly two more decades. The upgraded ground stations are designed to handle increased network capacity, a requirement as the airspace becomes more crowded with non-traditional aircraft.
Kathy Crandall, President of Mission Networks, Space & Mission Systems at L3Harris, emphasized the operational impact of the upgrades.
“L3Harris is propelling the FAA’s modernization vision forward by delivering an advanced surveillance infrastructure that will define the future of our airspace system and ensure increased safety for all air travelers.”
Crandall added that expanding network capacity ensures the United States maintains its position in global air traffic management.
Alignment with broader FAA modernization initiatives
This surveillance contract aligns with ongoing FAA efforts to replace aging infrastructure across the National Airspace System. The agency has been executing its Facility Replacement and Radar Modernization (FRRM) strategy, which targets the replacement of over 370 air traffic control facilities and 618 radars that average 36 years of age.
L3Harris is already involved in parallel infrastructure projects for the FAA. The company is currently executing the FAA Telecommunications Infrastructure (FTI) upgrade. That project replaces legacy copper wire connections with high-speed fiber optic networks across FAA facilities, providing the bandwidth necessary to support emerging aviation technologies like electric aviation vertical takeoff and landing (eVTOL) aircraft and uncrewed aerial systems.
AirPro News analysis
The extension of the L3Harris mandate through 2045 highlights the reliance of the FAA on established defense and aerospace contractors to execute its long-term modernization goals. As the National Airspace System transitions to accommodate AAM and widespread drone operations, the data bandwidth and latency requirements for air traffic control will increase exponentially. We view the concurrent execution of the surveillance network upgrade and the FTI fiber optic rollout as a necessary synchronization. Without high-speed ground data transmission, the benefits of satellite-based, real-time tracking for low-altitude and autonomous aircraft would be severely bottlenecked.
