ADEX 2025 – Safran Electronics and Defense unveils Skydex NAVWAR, a software tool allowing third party integrators to build sovereign spoofing platforms

On Day 3 of the Seoul exhibition Safran Electronics and Defense unveiled Skydex NAVWAR, a software solution that can be used by other integrators to develop a national spoofing counter-unmanned air systems (C-UAS) solution using their hardware of choice

Not all customers want to acquire turnkey solutions from foreign providers to counter the UAS threat they are facing. Considering this, Safran Electronics and Defense decided to extract the spoofing element of its Skyjacker system, in use in the French forces and other international customers, making it a software product that can be provided to other integrators to generate an effective spoofing C-UAS national solution.

At ADEX 2025 this was exhibited on a hardware system provided by ETOBB, the Korean Safran partner. This included a tripod-mounted antenna, a high-power amplifier and a computer, the South Korean company being the first known customer/partner to develop what it calls SPG-S GNSS Spoofer. A Safran GSG-7 GNSS Simulator and a Safran SecureSync time server completed the system. EDR On-Line understood that the software product has been already sold to the US where it is in use by military customers. The system is fully secure and is antenna and hardware agnostic.

It is designed to be integrated in command-and-control suites, and can spoof signals of all known GNSS constellations, GPS, NavIC, Galileo, BeiDou-2 and -3, QZSS, SBAS, as well as low earth orbit positioning, navigation, and timing signals and custom signals, in all bands.

It has a 1,000 Hz simulation iteration rate, can work either on Windows or Linux operating systems. It can be monitored and controlled at distance, allowing remote spoofing operations without the need of an operator. A plug-in software development kit allows custom plug-in creation, adapting the tool to the user.

It can also be added to existing C-UAS and electronic warfare systems, improving their performances.

With the constantly increasing threat by drones, Safran Electronics and Defense is looking at the wide C-UAS market, as many nations still need to enhance operational readiness in that field with a real-time spoofing function, capable to undermine the UAS threat not only in the military world, but also in for law enforcement and critical assets protection missions.
