Skydel GNSS Simulation Software

Advanced Simulation with Modern, Software-based Flexibility

Safran’s advanced Skydel GNSS software is more flexible, scalable, customizable, upgradeable, and cost-effective compared to traditional FPGA-based simulators. The way the world thinks about GNSS simulation today is not the same as even a few years ago, thanks to leaps in technology with software-defined radios and COTS components.
