Elear Sonics

Elear Systems is a Polish defence technology brand based in Wrocław, developed by Elear Sonics Sp. z o.o. Founded in 2026, the company designs integrated systems for military and crisis-response teams working where cellular networks, satellite links or conventional infrastructure may fail. Its approach connects resilient communications, threat detection and command into a shared operational picture.

NODUS is a tactical MANET communications system intended to help field teams share data and coordinate when other links are unavailable. CUSTOS is a passive radio-acoustic detection system designed to identify radio-controlled, tethered and fiber-optic FPV drones. Legio is distributed command software that brings system data and field reports together for operational teams and headquarters, including in settings without internet access. Optio, currently at the concept stage, aims to provide integrated situational awareness across authorized users.

Elear Systems also applies its technology to municipal crisis management, supporting coordination during events such as floods, blackouts and network outages.
