STATE-OF-THE-ART, PLATFORM-DESIGN COUNTER-UAS SOLUTION
The SIGN4L SKYSHIELD TM is a state-of-the-art counter-UAS solution in a platform design that combine jamming and spoofing for reliable point protection. This solution jams the full GNSS spectrum and spoofs the full commercial GNSS spectrum to protect a specified area of interest.
The typical jamming range for unprotected GNSS platforms is up to 10 km, while the solution also jams drone command and control channels with a typical jamming performance of 2:1 from a drone’s remote control.
