GNSS TESTING SOLUTIONS
GNSS Simulation for Reliable Testing in a Disrupted Signal Environment
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.
Why GNSS Simulation Matters
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.
GNSS simulation enables organisations to:
Test performance under jamming and spoofing scenarios
Validate receiver accuracy and system resilience
Accelerate product development and certification
Reduce field testing costs and risks
Ensure compliance with industry and regulatory standards
