Typical modeled parameters
Calculates signal and noise margins across your orbit and service profile to predict realistic device connectivity and data rates.
Assesses end‑to‑end delay across your target orbit to set clear expectations for alarm handling, reporting speed, and overall service responsiveness.
Maps how far and how reliably your service can reach by combining orbital geometry, elevation constraints, and real‑world device distribution.
Reveals how much traffic your system can truly support under realistic load, helping you understand usable throughput and future scaling potential.
Analyzes Doppler impacts across your orbit to ensure timing stability, robust uplink access, and consistent device performance in motion.
Identifies achievable data rates across transparent and regenerative payloads so you know exactly which message sizes and reporting intervals your service can deliver.
All modeled parameters and KPIs are tailored to your satellite configuration, spectrum, and performance objectives.

Frequently asked question on the subject of 5G NTN NB-IoT Feasibility Study
The feasibility study is designed for satellite operators, service providers, system integrators, and technology investors preparing or exploring a 5G NTN NB‑IoT service. It is relevant both in early concept phases when key assumptions need validation and in later stages when architecture decisions, performance expectations, and commercial viability must be confirmed before moving toward deployment.
The study provides evidence‑based insight into expected performance, system behavior, and architectural trade‑offs under real NTN conditions. By combining standards‑aligned modeling with proven simulation frameworks, it highlights limitations, dependencies, and cost drivers early. This allows you to avoid redesigns, delays, and misaligned investments at later stages.
All assumptions are grounded in 3GPP specifications and Gatehouse Satcom’s hands‑on experience with NTN testing, demonstrations, and system implementations. The models reflect practical satellite characteristics such as latency, link budgets, Doppler behavior, and coverage dynamics. This ensures that results align closely with what can be achieved in real deployments.
The study supports confident decisions on system architecture, technology readiness, performance feasibility, and roadmap priorities. It provides a shared and validated basis for aligning technical and commercial stakeholders on whether, when, and how to proceed with a 5G NTN NB‑IoT service.
The outputs are structured to support external communication and assurance. They can be shared with partners, used in discussions with regulators, and included in investor or stakeholder evaluations. This demonstrates that key technical and commercial risks have been thoroughly analyzed and provides a credible foundation for next‑step decisions.
