Counter‑UAS jammer systems use electronic warfare techniques to disrupt the control, telemetry, video, and navigation signals of unauthorized or hostile drones, forcing them into safety protocols or loss of control. These systems operate across multiple frequency bands, providing wide‑area coverage, continuous 24/7 operation, and rapid activation to protect critical infrastructure, sensitive sites, and high‑risk environments from aerial threats. By neutralizing command and GNSS links, counter‑UAS jammers are a key non‑kinetic layer of modern airspace security and defence.
