German defense electronics firm HENSOLDT unveiled SkyBarrier at Eurosatory 2026 in Paris on June 16, positioning the system as a mobile broadband jammer for satellite-based navigation signals. The company describes the system as an electronic countermeasure intended for armed forces and government agencies seeking to deny adversaries the use of navigation-dependent systems.
SkyBarrier is designed to jam all four major global navigation satellite systems simultaneously: GPS, GLONASS, Galileo, and BeiDou. HENSOLDT states the jamming effect covers both civilian and military signal variants, including encrypted signals, across the full range of currently relevant frequency and coding variants.
The system is built around rapid deployment: HENSOLDT says two operators can complete setup — including mast assembly and cabling — within minutes, with activation via a mechanical front-panel switch requiring no software configuration. The complete system consists of a single portable electronics unit, an extendable telescopic mast, and associated accessories.
HENSOLDT designed SkyBarrier for incremental upgradability, stating that new signal types can be added by replacing individual components rather than the full system. The company also notes a minimal physical interface profile — three hardware interfaces with no external data communication pathways — as a deliberate cybersecurity measure.
