C-V2X Connectivity Testing

Vehicle-to-everything (V2X) communication relies on precise timing synchronization to ensure low latency and message integrity. Safran’s SecureSync® Time Server and mRO‑50 miniature rubidium oscillator provide ultra-stable time references for validating C‑V2X systems. Combined with Skydel-powered GNSS simulators, engineers can replicate real-world RF conditions and interference scenarios to guarantee connectivity performance—even in GNSS-challenged environments.

Autonomous Driving Robustness

Autonomous vehicles require resilient positioning and timing to maintain safety in complex environments. Safran’s GSG‑8 Gen2 and GSG‑Wavefront simulators enable developers to test sensor fusion algorithms and navigation stacks against multipath, jamming, and spoofing threats—before hitting the road. By simulating urban canyons, tunnels, and contested RF conditions, Safran helps OEMs validate robustness and compliance for Level 3–5 autonomy.

Validate GNSS Subsystems in Cars

GNSS receivers are critical for navigation, ADAS, and emergency services. Safran’s Skydel-based simulators allow automotive engineers to validate GNSS subsystems under controlled, repeatable conditions, including multi-constellation, multi-frequency signals and interference scenarios. This ensures accurate positioning and timing performance across diverse geographies and driving conditions.

HIL Testing

Hardware-in-the-loop testing accelerates development by integrating real vehicle components with simulated environments. Safran’s GNSS simulators deliver high-fidelity GNSS signals with ultra-low latency, enabling seamless HIL setups for ECUs, navigation modules, and connectivity systems. This approach reduces field-testing costs while improving reliability and safety validation.
