Government and Defence
Securing mission-critical communications with resilient, scalable ground infrastructure
We serve the complex needs of government and defence organisations worldwide. We deliver RF and satellite ground segment solutions that form the backbone of secure, resilient communications systems for governmental, civil defence, and institutional networks. With over three decades of experience in RF design and manufacture, ETL supports operations from secure tactical links in the field to strategic national and multi-national programmes.

Challenges & solutions
- Heightened geopolitical tensions and a rapidly evolving threat landscape means that network integrity and resilience is of more importance than ever before.
- Ground architectures are becoming increasingly complex as technologies converge; multi-X operation, the advent of Q and V-band, 5G NTN integration, and hybrid analogue/digital networks make diverse and challenging demands of operators.
- Modern operations, both in the field and at the ground station, require flexibility and scalability as capacity demand continues to increase globally, requiring continuous investment from both government and commercial bodies who wish to stay competitive.
- Our resilient hardware platforms are designed for mission-critical applications. Across our portfolio, we build in redundancy wherever possible, including features like automatic path switchover in case of card failure, dual redundant PSUs/CPUs, multi-tiered switching architecture and more. We operate SNMPv3 and HTTPS protocols as software standards across the vast majority of our range, ensuring secure communications.
- With our vast in-house experience and capability from design to delivery, ETL can reduce project complexity through its end-to-end service, streamlining procurement, system design, testing, network management, maintenance and lifecycle management/support. Our portfolio spans both analogue and digital RF product, making us ideally positioned to consult on both traditional and hybrid ground architectures.
- ETL has developed an expansive modular platform in GENUS, which enables users to rapidly reconfigure systems through plug-and-play modules, simplifies spares logistics, and reduces time and rack space requirements.
Next-generation ground networks
As satcoms evolves, the transition towards Q/V-band operation and hybrid or fully virtualised ground architectures presents opportunity and challenge to operators. Higher frequency bands unlock greater bandwidth, improved interference management, and enhanced data throughput, but will require RF infrastructure designed to manage propagation sensitivity at mmWave. Simultaneously, hybrid and cloud-enabled ground stations are redefining network deployment and scaling, requiring seamless integration between RF and virtualised environments. ETL Systems delivers adaptable solutions that integrate with emerging architectures, providing a clear pathway for future expansion. Want to know how we can support you?
