Gatehouse Satcom provides the software, hardware, core emulation, channel realism, and automated testing needed to move seamlessly from lab validation to field trials and early operations.
The validation platform helps operators confirm technical and commercial feasibility before committing major investments. Early validation reduces redesign cycles and supports strong governance decisions.
This approach reflects more than a decade of NTN development and validation experience, and is engineered to match 3GPP requirements with high fidelity.
Gain a structured setup for testing system assumptions, link behavior, and business case feasibility. This reduces uncertainty before major investment decisions.
Confirm how your NTN NB-IoT components operate together. From UE and emulator to eNodeB and core elements, you get clarity on compatibility and performance.
Show internal and external stakeholders a working NTN NB-IoT environment. Gatehouse Satcom tailors the setup, supports validation activities, and helps interpret results to strengthen confidence and accelerate rollout readiness.
Use evidence-based validation to support investment decisions. Proven NTN NB-IoT performance and documented test results help you build a solid business case and reduce commercial uncertainty.
The 5G NTN NB-IoT Validation Platform supports both technical validation and business readiness. It enables operators, service providers, and developers to build evidence, refine architecture, and demonstrate capability together with Gatehouse Satcom’s engineering team.
Shorten integration cycles and reduce risk before investing in hardware or satellite resources.
Verify eNodeB, UE, emulator, and core interoperability in a controlled test environment. Configure link conditions, run systematic tests, and resolve issues early with direct support from Gatehouse engineers.
Gain technical confidence and data-backed evidence to support funding and program decisions.
Confirm system architecture assumptions and performance margins. Explore link budgets, propagation behaviour, and capacity under GEO, MEO or LEO conditions using reproducible scenarios.
Accelerate stakeholder alignment and strengthen your position in bids or commercial negotiations.
Demonstrate interoperability, standards alignment, and real-world feasibility for partners, investors, or customers. Gatehouse supports staging, execution, and interpretation of results.
Before activating live services, verify that UE, eNodeB, and core behaviours meet operational expectations under realistic GEO, MEO and LEO conditions.
Identify and correct issues early to reduce troubleshooting during initial service roll-out.
Stay ahead of standard evolution and shape the next generation of NTN capabilities.
Use Validation Platform for collaborative development, research, or early evaluation of upcoming 3GPP features.
The 5G NTN NB-IoT Validation Platform brings software components, hardware options, and engineering support together in a single environment designed to shorten setup time, ensure interoperability, and provide full visibility into system behavior.

Controlled E2E validation using reference UE or COTS UE, eNodeB , and core network (NEMU emulator or commercial). Orbit channel conditions via emulator; OAM/FCAPS (NETCONF) for configuration and metrics; automated Test Control orchestrates runs.
In‑orbit validation with ground‑based eNodeB and satellite as transparent relay. Core network (NEMU or commercial). Operator OAM/FCAPS connects to eNodeB.
In‑orbit validation with eNodeB onboard the satellite (regenerative). Ground station provides RF path; core network (NEMU or commercial). Operator OAM/FCAPS supervises eNodeB.
Perspectives
We found the Gatehouse Satcom team to be very responsive and flexible in troubleshooting the issues with our implementation, resolving the problems, and explaining the operation.
We were very pleased with the service and plan to use the Gatehouse Satcom team again in the future.
The Gatehouse Satcom technical and program management support has been excellent. No obvious areas for improvement.
The Gatehouse team has been a great partner. They have operated like a partner and not a vendor and have been open to feedback and provided own feedback as well.

Validation Campaigns
By validating 5G NTN NB-IoT technology in collaboration with operators and device partners, we have transformed research results into practical tools customers can apply directly.
Whether you are evaluating NTN, integrating systems, or preparing for launch, we offer engagement models that match each stage of development and deployment.
License the 5G NTN NB-IoT eNodeB for operational use. Get onboarding, ICDs, integration support, training, and ongoing updates so you can deploy, configure, and run services with confidence across LEO, MEO, and GEO.
Use a configurable NB-IoT NTN environment for lab, HIL, or field validation. Exercise real NTN protocol behavior, test interfaces with commercial UE, and verify performance under LEO, MEO and GEO link conditions before moving to full integration.
Work with our engineers on architecture reviews, payload fit, and concept of operations. Get simulation-based studies, link assumptions, and a practical integration plan aligned with your timeline.
Our commercial team can help clarify scope, technical needs, and the most suitable engagement path for your device development stage.
Talk to SalesThe 5G NTN NB-IoT Validation Platform provides a flexible, standards aligned environment rather than a single fixed configuration. The specifications below outline supported interfaces, configurations, and test capabilities so you can understand how the suite fits into your lab, HIL, or early field setup.

Frequently asked questions on the subject of 5G NTN NB-IoT Validation Platform
A controlled test lab needs stable RF paths, correct eNodeB–NEMU provisioning, UE configuration, and isolation from external signals.
The platform can introduce stress scenarios such as low‑SNR conditions, worst‑case Doppler, CE‑level challenges, burst attach attempts, large MO/MT payloads, and paging/TAU edge cases.
Realistic NTN testing requires modelling delay, Doppler, SNR, fading, CE levels, tones (1/3/6/12), and 3.75/15 kHz subcarrier spacing. The Validation Platform supports these parameters through built‑in orbit/SNR emulation or external channel emulators.
GEO introduces long, stable delays, minimal Doppler, and specific CE‑level and paging timing behaviours. Re‑creating these conditions requires consistent RF paths and accurate delay models. The platform provides controlled delay, channel behaviour, and full visibility of attach and paging flows.
Testing NGSO regenerative mode requires handling fast Doppler shifts, dynamic timing, onboard scheduling, and SIB31/ephemeris synchronization. The Validation Platform models these effects so you can evaluate NGSO behaviour without needing real satellite access.
The platform includes Gatehouse eNodeB software, Rel‑17 UE options, the NEMU core emulator, an automated Test Framework, and an optional 3U integration rack with RF front‑end and SDR radio. It provides everything needed for controlled, end‑to‑end NTN NB‑IoT testing in the lab.
