At the defense and security show Eurosatory 2026 in Paris, Hensoldt is presenting SkyBarrier, a mobile jammer for satellite-based navigation signals.
The system is designed as an electronic countermeasure. It is aimed at armed forces and government agencies that need to protect critical infrastructure and personnel from the use of enemy navigation-based systems.
The SkyBarrier is capable of simultaneously jamming all GNSS signals. The jamming effect extends to both civilian and military variants of these systems, as well as encrypted signal variants. The system thus covers the entire range of currently relevant frequency and coding variants.
A key feature of the system is its mobility and operational speed. Two people can set up SkyBarrier, including mast assembly and cabling, and have it ready for operation within a few minutes. Activation then takes place via a mechanical switch on the front panel in a matter of seconds — no software-based configuration is required. The complete system consists of a single portable electronic unit, an extendable telescopic mast and the associated accessories.
The system is designed for future expansion: new signal types can be retrofitted by replacing individual components without having to replace the entire system. In terms of security and cybersecurity, the SkyBarrier offers a high level of protection; the electronics have only three physical interfaces, which do not allow any external data communication.
