Safran Skydel GNSS Simulation Software

The way the world thinks about Safran Skydel 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. Compared to traditional FPGA-based simulators, Safran’s advanced solutions are inherently more flexible, scalable, customizable, upgradeable and cost-effective. 

Safran’s Skydel Simulation Engine offers the best of both worlds: high-end performance you expect from a top-grade GNSS simulator, coupled with the economy of scale and flexibility of its software-defined architecture. 

Packed with a rich feature set including a 1000 Hz simulation iteration rate, remote control from user-defined scripts, and a software-defined architecture, Skydel offers unmatched flexibility and scalability. 

And all of this, packaged in a modern, streamlined user interface – with an almost unlimited number of signals. 

Skydel offers real-time GNSS simulation of the highest quality.

All Constellations, All Signals

A solution ready to scale with your needs, simulate all visible satellites for all constellations and all frequencies with a 1000 Hz iteration rate and ultra–high dynamics. Create scenarios and update them on-the-fly. 

Integrated Jamming & Spoofing

With no additional hardware required, advanced jamming and spoofing on Safran’s software-defined platform allows users to simulate multiple threats simultaneously. Skydel software automatically determines signal dynamics between each, saving you time. 

Open Source Plugins & Community

Safran's Skydel forum connects you directly with users like you across many industries and leading research universities. Safran's plugin Github is host to everything you need to tailor Skydel to your simulation needs. 

Powerful Automation

Easy to use and comprising hundreds of commands, Skydel’s API brings an unparalleled level of control over simulation, enabling you to build complex, elaborate and repeatable scenarios with open source client libraries for Python, C# and C++. 

Software-Based Design

With a software-based design, Skydel scales to match customer budgets and can quickly adapt to new signal types, constellations, and other nav sensors. Moreover, because performance leverages the latest COTS hardware technology, Skydel has lower lifecycle costs and faster time to market.
