The DroneNet System

The Drone Threat

A revolution is taking place these days as drones are being used to pivot the whole nature of warfare. The use of inexpensive, off-the-shelf drones by adversaries has skyrocketed in recent years, manifests a genuine threat to National Security.  

Non-state forces & resistance movements are using drones for a variety of intelligence gathering and/or attack missions. Drones are now a real, asymmetrical threat to the frontline forces which are now exposed not only on land, but also from the air. 

One of the greatest challenges when dealing with the drone threat is detection. Existing radar systems are designed to detect much bigger threats, with a stronger thermal & spectral signature. Most commercial drones are difficult to spot electronically because they’re small, fly low and don’t carry a transponder to signal their positions. 

Multi-Layered Counter Drone Defense 

Neutralizing such a fast-evolving, asymmetric threat requires a holistic approach. 

Netline’s DroneNet platform offers a multilayered, complete counter drone solution for Detection & Identification, localization and Mitigation of hostile drones, all monitored and controlled by a central C4I.  

The solution includes three layers defense system, to be customized according to the operational needs;

Detection & Identification

Drone Detection techniques are based on continuous analysis of the time & frequency domains by RF sensors. Preloaded spectral signatures of all commercially available drones are used as the system’s database.  During the detection phase, the DroneNet searches for activity patterns corresponding to the stored signatures and alerts once a match is found. The direction of the drone, as well as its type, are determined by the receiving RF sensors and indicated on the system’s C4I. 
When trying to detect drones in a spectral-saturated environment, detection time is of the essence. The DroneNet utilizes various SIGINT techniques in order to achieve a reliable yet rapid detection on the one hand and a low rate of false alarms on the other hand, presenting the first phase out of a three steps counter drone solution.


Direction Finder (DF) is a type of sensor used to locate the direction of unknown signals. 
A single DF sensor measurement provides the direction of the transmitter/ drone, whereas using measurements from a network of DF sensors from different locations, can determine a precise location of the drone.
By deploying several RF sensors, in accordance with the operational needs, the precise location of the threat will be located and displayed on the system’s C4I console. The accuracy of the estimated location is determined by the number of the deployed sensors and their location.  
Once the drone take-off, all signals transmitted by the drone will be detected, identified, and located. In some scenarios, the system can locate the drone even before take-off.  


When a drone is detected, the system alerts the operator and initiates mitigation procedures to neutralize the threat. Upon detection the RF jammers block the communication between the drone and its operator on ISM bands, as well as any GPS signals used by the drone.
Each band can be programmed to block either the entire frequency band (broadband) or to be limited to selected channels or active drones’ frequencies. Netline’s DroneNet jammer is composed of 5 bands that cover all potential drone frequencies (433MHz, 900MHz, GPS and Wi-Fi).  
The system’s modular design enables future upgrade and insertion of additional frequencies and threats.

Mission Control 

When a drone is detected, the classification of the drone, as well as its precise location, will be displayed on the map on the system’s console. 

The C4I segment allows full control of the mission and provides real-time display of the detected threats. The C4I segment was designed for easy and intuitive operation, by a single operator.

The C4I operator can decide in real time whether to initiate the mitigation process manually or automatically upon detection. 

DroneNet for Any Mission

The DroneNet platform offers a range of configurations, from large scale, fixed installation designs to rapid deployment and man-pack systems, designed to meet tactical mission requirements according to military standards.
