Built for Multi-Domain Situational Awareness – MDSA, our 5G NTN software ensures encrypted, resilient communications across air, land, sea, and space – even when infrastructure is denied or contested.
Standardized 5G NTN offers a faster, more cost-effective alternative to traditional military satellite systems. Built on 3GPP standards, it enables rapid deployment, reduces custom development overhead, and improves interoperability between allied forces.
Instead of waiting years to field proprietary solutions, military organizations can adopt existing satellite infrastructure and adapt it to their own needs – without losing control or security.
Standardized 5G NTN gives defense agencies a running start. Instead of building custom systems from the ground up, they can fast-track deployment by using commercial-grade, 3GPP-compliant technologies already in orbit. This approach cuts years off timelines — and gets secure, global connectivity in place faster, when agility matters most.
3GPP standards unlock mass production. Existing 5G device ecosystems reduce procurement costs and simplify logistics. Military forces can adapt commercial equipment — from terminals to antennas — at a fraction of the cost of custom-built satcom solutions.
With 5G NTN, coalition forces can talk – across vendors, nations, and networks. Standards-based 5G NTN enables seamless roaming across orbits, networks, and vendors – with a single terminal, ready for multi-theater deployment.
On 28 April 2025, over 30 GW of power was lost across the Iberian Peninsula – darkening homes, roads, and critical infrastructure in Spain, Portugal, and even parts of France. Mobile towers, emergency services, and transport systems went down for hours, risking civilian safety, economic stability, and national resilience.
But what if defense and public networks could remain operational even during such catastrophic failures?
In this scenario, a 5G NTN constellation with onboard RAN and core processing ensures continuity when terrestrial infrastructure is degraded, denied, or compromised:

As defense organizations begin to adopt standardized 5G Non-Terrestrial Networks, one requirement stands above the rest: trust. Not just in the signal – but in every component that makes that signal possible.
At Gatehouse Satcom, we specialize in developing the software foundation that powers 5G NTN systems across the entire chain – from the user terminal to the satellite payload to the ground station infrastructure. This isn’t just about enabling connectivity. It’s about enabling sovereign, secure, and standards-aligned connectivity – tailored to defense environments.
Whether deployed at the tactical edge, embedded in national SATCOM architectures, or integrated into coalition C4ISR networks, our software is built to provide:
Across the globe, defense organizations are rethinking how they build, operate, and secure their communications infrastructure. From the U.S. Department of Defense to European ministries and allied coalitions, the trend is clear:
Future military networks must be more flexible, more secure – and based on trusted, standardized technologies.
Gatehouse Satcom’s 5G NTN software solutions align with this shift.
Built on open 3GPP standards and designed for defense environments, our technology enables armed forces to take advantage of commercial innovation without sacrificing control, visibility, or sovereignty. Whether integrated into private networks on the ground, space-based systems, or national architectures, our modular software stack supports secure, mission-tailored deployment across all domains.

Yes — and often more so.
Standardized 5G architectures don’t mean exposed systems. You can layer encryption and authentication mechanisms alongside or within the 3GPP stack. In fact, having a well-understood, openly vetted protocol makes it easier to spot vulnerabilities, not hide them. Combined with trusted software implementations and sovereign deployment control, standardized doesn’t mean compromised — it means manageable.
Time, development cost, and long-term sustainment.
Using 3GPP-based 5G NTN avoids the need to develop bespoke satellite communication stacks from scratch — cutting years off project timelines and saving millions in R&D. It also means militaries can adapt commercial-grade equipment (terminals, antennas, radios) at scale, reducing per-unit costs dramatically. Standardized = affordable at volume.
It’s open, modular, and ready now.
Traditional milsatcom is custom-built, closed, and often isolated by design. 5G NTN is built on open standards that enable interoperability, rapid deployment, and integration with terrestrial and coalition networks. It’s the difference between buying a secure phone off the shelf — and spending five years designing one from scratch.
Yes. That’s one of its biggest strengths.
With transparent satellites and ground-based control, 5G NTN systems can operate independently of local infrastructure — and remain resilient in contested environments. The ability to switch seamlessly between terrestrial, airborne, and space-based nodes means a connection can be maintained even when parts of the network are degraded or lost.
They already are — with 3GPP standards.
Because 5G NTN follows the same global standards used by many NATO and partner nations, different forces can use the same infrastructure while maintaining their own control layers. Through network slicing and secure authentication, multiple militaries can interoperate without sacrificing sovereignty or security.
We provide the trusted software core.
From user devices to ground stations, Gatehouse Satcom delivers the software that enables secure, standards-based 5G NTN communications. Defense partners gain modular, inspectable software components — free of vendor lock-in or hidden dependencies — to build sovereign systems on top of commercial infrastructure.
