Starting 2026 with CELEOS 1.3 and a clear path for 5G non-terrestrial networks

Non-terrestrial networks are reaching a point where technical exploration gives way to operational decision-making. Understanding real system behaviour now matters as much as architecture and standards. 

At the start of 2026, we are releasing CELEOS 1.3, the latest version of our satellite channel emulation platform, built to help teams understand how 5G actually behaves over satellite links before committing to hardware, spectrum, or infrastructure. 

Why CELEOS 1.3 matters 

Unlike theoretical models or simplified simulations, CELEOS delivers high-fidelity channel emulation that reflects real satellite dynamics. This allows teams to examine latency, Doppler effects, link availability, and mobility in a controlled, repeatable environment. 

CELEOS 1.3 builds on this foundation through targeted improvements across interoperability, usability, and operational robustness. Support for DiFi v1.2.1 improves integration with modern digital RF infrastructures and SDR platforms, making CELEOS easier to deploy in advanced laboratory and testbed environments. 

The platform now offers more precise manual control over USRP signal levels, enabling better calibration and more realistic test scenarios. Simplified installation and extended configuration options reduce setup time while increasing flexibility across different lab setups. Enhanced configuration handling and operational controls improve how scenarios are reused, managed, and iterated during testing. 

To improve situational awareness during experiments, CELEOS 1.3 introduces clearer visual indicators for emulation status and satellite visibility. The ability to load satellite constellation TLEs directly from online databases ensures that scenarios stay aligned with real-world orbital data. 

Together, these enhancements make CELEOS a stronger reference platform for high-fidelity NTN evaluation, allowing teams to move from abstract assumptions to evidence-based understanding. 

Supporting better decisions in 5G NTN 

As non-terrestrial networks become part of real deployment strategies, the cost of getting decisions wrong increases. CELEOS helps reduce that risk by giving teams a shared technical reference point that can be used across engineering, integration, and strategic planning. 

Whether validating a new NTN use case, comparing technology options, or preparing for integration with terrestrial networks, CELEOS enables organizations to see how systems behave before resources are committed in the field. 

Meet Lasting Software in 2026 

Beyond online engagement, direct dialogue remains a key part of NTN development. In 2026, Lasting Software will be present at major international events across the space, defence, and connectivity ecosystem: 

• MWC Barcelona 2026 (2–5 March | Barcelona, Spain) - within the GSMA stand 

• SATShow 2026 (23–26 March | Washington, D.C., USA) - Stand #1222 

  
  

These events provide an opportunity to discuss real-world NTN challenges, exchange perspectives, and explore how platforms like CELEOS are helping turn complex satellite connectivity into something that can be confidently evaluated and planned. 

Moving from exploration to confidence 

CELEOS 1.3 represents more than a software update. It reflects a broader shift in how non-terrestrial networks are being approached - from theoretical exploration toward evidence-based decision-making. 

As 2026 begins, Lasting Software remains committed to supporting that transition, providing both the tools and the dialogue needed to bring clarity to one of the most complex areas of modern connectivity.
