ION GNSS+ 2025 Conference 2025 – Baltimore (USA), September 08, 2025 – Safran Electronics & Defense is proud to unveil Skydel AI, a breakthrough in GNSS simulation technology that leverages Artificial Intelligence to automate and simplify simulation scenario setups like never before.

Skydel AI is designed to streamline GNSS simulation scenario creation through intelligent automation and an intuitive interface. By using natural language commands, Skydel AI enables users to query about GNSS/Skydel topics, request assistance, and dynamically configure simulation parameters by creating Python code to be used by Skydel. Skydel AI – eliminates complexity and significantly reduces setup time.

“Soon available as part of Safran’s Support offerings, Skydel AI can help customers drastically improve their development cycles by accelerating manual scenario tuning and reducing long test cycles within Skydel,” explains Pierre-Marie Leveel, Program Director for PNT at Safran. “Already established as the most flexible, robust, and accurate GNSS simulation engine, Skydel never stops innovating and delivering what the market requires – whether it is more realism, higher accuracy, more environment complexity, or ease of use”.

Building on these capabilities is the new AI-Powered Tropospheric Model, which enhances Skydel’s tropospheric simulation by using real-time weather data and AI predictions to improve wet delay accuracy. Integrated with the Open-Meteo API and Skydel’s system, it relies on a neural network trained on 14 million samples from 221 GNSS stations, delivering up to 88% more accuracy. This model will be available in a future release of Skydel.

This technical breakthrough reflects Safran Electronics & Defense’s commitment to redefining the future of GNSS simulation with intelligent, adaptable, and high-performance solutions for mission-critical applications.
