Testing and Simulation: GPS/GNSS Simulators | SAFRAN

Safran’s GPS/GNSS simulators provide realistic, scenario-based satellite signal simulation for the development, validation, and testing of GNSS receivers. Supporting all global and regional constellations (GPS, Galileo, GLONASS, BeiDou, QZSS, NavIC, LEO), they offer a powerful, flexible, and cost-effective testing solution.

Benefits

• Sub-nanosecond signal accuracy
• Scenario-based testing with full control over signal parameters
• Scalable automation via API and scripting
• Low-latency Hardware-in-the-Loop (HIL) capability
• Compact, COTS-based platforms for easy integration
• Future-proof with software updates and modular expandability

Key Features

• Skydel GSG-7: High-performance GNSS simulator with 1000 Hz simulation rate
• Real RF signal simulation for all GNSS constellations
• Multi-antenna support for UAV and vehicle testing
• User-friendly interface with full control over satellite count, signal strength, atmospheric effects, and more
• Integration with SDRs (Software Defined Radios)
• Automated test sequences for complex validation plans

Typical Applications

• Development and validation of GNSS receivers
• Testing in GNSS-denied or spoofing-prone environments
• Hardware-in-the-Loop (HIL) simulations
• UAV and vehicle navigation
• Research and education in satellite navigation
• Certification and compliance testing

Additional Information

Safran’s GPS/GNSS simulators offer a powerful, flexible, and future-ready platform for anyone developing, testing, or validating GNSS systems. Powered by Skydel software and built on a modular architecture, they make even complex scenarios easy to implement—from single tests to large-scale automated campaigns.
