Our team recently implemented non-terrestrial networks, here's what every engineer needs to know about this technology in 2026.
Non-Terrestrial Networks for IoT: LEO satellite constellations, 3GPP NTN standards, Skylo protocol, Astrocast, and hybrid terrestrial-satellite architectures. This covers the critical aspects that practitioners encounter in real deployments, from initial design decisions through production scaling.
Leo Satellite Constellations
The foundation of LEO satellite constellations starts with understanding its core architecture. Modern implementations have evolved significantly from early approaches, incorporating lessons learned from large-scale deployments across diverse environments.
When evaluating LEO satellite constellations, consider the tradeoffs between complexity and performance. In my experience, teams that invest time in understanding these fundamentals avoid costly redesigns later.

3Gpp Ntn Standards
Implementing 3GPP NTN standards requires careful attention to resource constraints. Most IoT devices operate under strict memory, compute, and power budgets that fundamentally shape design decisions.
I've seen production deployments fail because teams underestimated the impact of 3GPP NTN standards on overall system reliability. Testing under realistic conditions — not just lab setups — is essential.

Skylo Protocol
The practical aspects of Skylo protocol demand hands-on experience with real hardware. Simulation helps, but it can not fully replicate the electromagnetic, thermal, and timing challenges of physical deployments.
Our team has documented several best practices for Skylo protocol based on field deployments across manufacturing, agriculture, and smart infrastructure projects.

Practical Recommendations
Based on our field experience with non-terrestrial networks for iot, here are the key takeaways for teams starting new projects:
- Start with constraints: Define your power, memory, and bandwidth budgets before selecting components. I have seen too many projects redesigned mid-stream because they didn't account for real-world constraints.
- Test at scale early: Behavior at 10 devices differs dramatically from 10,000. Build your test infrastructure to simulate production loads from day one.
- Plan for updates: Every deployed IoT device needs a reliable update mechanism. Skipping OTA capability to save development time creates long-term technical debt that is expensive to retire.
Frequently Asked Questions
What's the best way to get started with non-terrestrial networks?
Begin with a development kit from a major silicon vendor. Prototype your core functionality first, then optimize for power and cost. Most vendors offer reference designs that accelerate initial development by 60-80%.
How does non-terrestrial networks handle security?
Modern implementations include hardware-based security features like secure boot, encrypted storage, and device attestation. Layer software security (TLS, certificate management) on top of these hardware roots of trust.
What are the main challenges with non-terrestrial networks in production?
The biggest challenges are reliable connectivity in harsh environments, managing firmware updates across distributed fleets, and maintaining security throughout the device lifecycle. Each requires deliberate architectural decisions early in development.
