- Portags combines drone detection and GNSS monitoring in single operational view
- RF sensors, passive radar and GNSS analysis integrated through sensor fusion
- 2025 Baltic Sea measurement campaign identified combined jamming and spoofing
- System modular and scalable for stationary or mobile deployment
- Follows Baltic Sea Security Summit agreement on information sharing
Hensec secure solutions has developed Portags, an integrated airspace and Global Navigation Satellite System monitoring platform designed specifically for ports to protect critical infrastructure against drones and GNSS manipulation. The system combines multiple detection technologies in one operational view, monitoring the airspace above a port for potential airborne objects while simultaneously checking whether satellite navigation signals are reliable or being disrupted. This enables security teams to centrally detect, assess and document drone activity and GNSS interference, addressing the growing threat of hybrid attacks against port infrastructure.
The system incorporates RF sensors that monitor relevant frequency ranges and detect active drone communication and control signals, including Remote ID data, telemetry and movement information. Passive radar complements this data by making non-transmitting and non-cooperative airborne objects visible, while the proprietary GNSS analysis systems monitor signal quality to detect interference and anomalies. During a 2025 measurement campaign in the southern Baltic Sea, a GNSS interference detector installed aboard a research vessel identified combined jamming and spoofing activity, with significantly stronger interference measured at sea than in the Port of Gdansk.
Portags brings together RF, radar, telemetry and GNSS data through sensor fusion, correlating and classifying information before displaying it centrally in a Common Operating Picture. The modular and scalable architecture can be deployed in stationary or mobile configurations across container terminals, tank farms, port entrances and automated terminals. Open interfaces allow integration into existing operations centres, with multiple sensor nodes connectable via a secure data network. The development follows the Baltic Sea Security Summit in late August, where Germany, Denmark, Estonia, Finland, Latvia, Lithuania, Poland, Sweden and Norway agreed to intensify information sharing and establish a joint task force.
