Space is a Network.
Constellations is Your Connection.
As AI, cloud computing and cyber threats accelerate the pace of network operations, satellite communications must embrace software-defined, interoperable architectures to keep pace with modern defense and commercial requirements.

As software-defined networking reshapes terrestrial communications, virtualization has become an essential and increasingly accepted foundation for the future of satellite ground infrastructure.
DIFI PlugFest USA 2026 will test the latest version of the DIFI standard in more realistic, end-to-end network environments, helping advance interoperability, certification and digital transformation across next-generation multi-orbit satcom systems.
The growing shift toward virtualized, software-defined ground systems is accelerating adoption of interoperability standards like DIFI, enabling satellite operators to reduce dependence on proprietary hardware while supporting scalable multi-orbit networks, 5G NTN integration and future AI-native architectures.
The approval of a certification program for the DIFI 1.1 standard marks a key step toward greater interoperability and trust in digital IF equipment, enabling both standardized performance assurance and independent third-party validation. As virtualization and cloud-based ground systems expand, DIFI compliance and feature-based certification will make it easier for organizations to specify, deploy and scale interoperable solutions.
The physical attack on an SES gateway in Israel marks a turning point in how we view satellite infrastructure, shifting the focus from cyber threats to the urgent need for kinetic resilience. By adopting standards like DIFI to virtualize and distribute ground segment operations, organizations can ensure connectivity remains seamless even if a specific physical site is compromised.
Routing this data directly into public clouds allows operators to clear the massive hurdle of machine learning ingestion while avoiding prohibitive egress fees. As NGSO constellations and vHTS architectures expand, applying these localized algorithms across deployed sensors will become mandatory for maintaining situational dominance and service quality.
With major players like Starlink and Eutelsat expanding their constellations, the 3GPP’s adaptable 5G NTN standard supports diverse network architectures by allowing the radio base station to reside either on the ground or on the satellite itself. This flexibility enables operators to balance proprietary mission requirements with the strict interoperability needed for direct-to-device connectivity.
DIFI settled on a streamlined VITA‑49 core to meet defense and commercial satcom needs while keeping implementation simple and widely adoptable. Because networks integrate at the IP level, satellite systems using DIFI/VITA‑49 can interoperate with terrestrial eCPRI‑based 5G, letting both ecosystems capitalize on NTN without compromise.
During a live demonstration, engineers pulled the plug on an antenna mid-transmission, yet the satellite link never faltered—automatically switching to a backup site without missing a beat. This breakthrough in digital IF technology promises more resilient communications for U.S. forces, with AI-powered insights emerging as the next frontier.
