Kratos Defense announced on October 8, 2026, that it successfully completed a multi-vendor demonstration of 5G satellite connectivity. The test utilized a virtualized architecture to enable interoperability between distinct 5G core platforms and hardware modems.
Why it matters
This demonstration addresses the industry push to move away from proprietary hardware and vendor-locked architectures in satellite communications. By enabling multi-vendor integration, operators gain the flexibility to source specific network components based on performance and cost.
The system integrated a virtualized Radio Access Network with Druid Software's Raemis 5G Core and GCT Semiconductor's GDM7275X 5G modem. The setup relied on Digital Intermediate Frequency standards and commercial off-the-shelf server hardware to replace traditional baseband units.
The players
Kratos Defense
A defense and security technology company providing specialized ground infrastructure and software for satellite communications.
Druid Software
A developer of private cellular network solutions, known for its Raemis 5G Core platform designed for enterprise and industrial applications.
GCT Semiconductor
A fabless designer of advanced 5G and LTE semiconductor solutions for mobile and IoT devices.
KT SAT
A South Korean satellite service provider that operates geostationary satellites and provides global connectivity services.
The details
The platform virtualizes signal processing into software applications, allowing operators to run infrastructure on commercial off-the-shelf server hardware. By utilizing Digital Intermediate Frequency — a method for digitizing radio signals for processing—the architecture enables the connection of a third-party 5G core to satellite links. This approach replaces vendor-specific baseband architectures that traditionally require specialized, integrated hardware.
Timeline
October 8, 2026: Kratos Defense completed the satellite connectivity demonstration.
The Tech Race
This development aligns with the ongoing 3GPP 5G NR NTN standardization efforts, which aim to unify mobile and satellite network protocols. It marks a significant move away from proprietary satellite ground segments toward an open, software-defined ecosystem.
This technology will eventually allow operators to lower infrastructure costs and expand 5G coverage into remote areas currently underserved by traditional towers. Users should expect no immediate change, as the system remains in the demonstration phase for network operators.
The takeaway
This successful integration of virtualized software and heterogeneous hardware suggests that satellite-to-5G networks are moving toward an open-standard model. Monitor future carrier announcements regarding the transition from traditional, vendor-locked ground stations to these virtualized platforms.
