GNSS Testing Solutions
Simulation, Validation & Resilience Testing
As reliance on GNSS for positioning, navigation, and timing continues to expand across industries, ensuring system accuracy and resilience has become mission-critical.
Real-world GNSS signals are increasingly affected by interference, spoofing, jamming, and environmental challenges, making controlled, repeatable testing essential for developers, integrators, and operators who depend on reliable performance.
GNSS simulation provides a safe, cost-effective way to test receiver behaviour, validate system performance, and prepare for real-world conditions—without the risks and unpredictability of live signal environments.
Our suite of GNSS simulators, powered by Safran’s advanced Skydel GNSS Simulation Engine, delivers the precision, flexibility, and scalability required for a wide range of testing scenarios.
From fundamental receiver testing to complex, multi-constellation, multi-frequency simulations, our solutions help organisations develop, verify, and deploy GNSS-reliant systems with confidence.
Testing GNSS-enabled systems in live environments alone is no longer sufficient. Signal disruption, evolving threats, and complex operational conditions demand repeatable, controlled testing that can replicate both normal and degraded scenarios.
We provide a flexible portfolio of GNSS simulation products designed to meet varying technical requirements and budgets. Our solutions range from essential configurations for routine testing to advanced, high-performance systems capable of simulating complex global scenarios.
Whether you are developing GNSS receivers, testing autonomous systems, validating timing networks, or supporting research and certification, our solutions deliver the accuracy and reliability required for mission-critical applications.
Our mission is to help organisations build, test, and deploy GNSS-enabled systems that perform reliably — even in the most challenging signal environments.
