and Limitations of Counter-Drone Solutions for First Responders

Ensuring the Safety of Our Skies: Unleashing the Power of Cutting-Edge Technology for Emergency Operations

Leveraging drone technology for emergency operations takes a fine balance to strike. From staying ahead of the latest drone advancements to understanding the unique environments and limitations in which drones operate and minimizing human and environmental threats.

It has become obvious that while using drones for search or rescue purposes, it is necessary to protect live operations from being shut down due to unauthorized drones hovering above emergency sites. That's where counter-drone systems come in.

Counter-drone Technology Segments from a Thousand-Foot View

The types of counter-drone capabilities generally fall under two overarching aims:

- Detection, tracking, and Identification (DTI) on one end,

- Threat suppression or Mitigation on the other end

That said an "all-in-one" and more advanced type of counter-drone solution has started being developed in more recent years and is proving extremely effective: it falls under the "Integrated Counter-drone Solutions" category.

Unlike traditional DTI and mitigation technologies (which often try to stretch their functionalities to adapt to drone threats), Integrated Counter-drone solutions have - by designed - been developed to safely takeover commercial drones.

In the world of drone detection, traditional methods have relied on radar, acoustic, optical, and radio frequency sensors. When an Unmanned Aerial Vehicle (UAV) is identified, the gathered data is swiftly processed and analyzed to provide real-time information about its location, altitude, and trajectory. This information is used to track the drone and determine the best course of action for averting the threat.

Radars although reliable in challenging conditions like poor lighting or adverse weather, require highly skilled personnel to properly operate them. Moreover, most radars fall short when it comes to distinguishing between identical drones, rendering them ineffective in allowing authorized drones to operate during live operations. They also often struggle to detect very small drones and can generate false alarms when picking up signals from non-drone objects like birds or cars.

Optical cameras offer an alternative approach, leveraging high-resolution or thermal imaging technology to capture images and videos of drones in flight.

Nevertheless, they come with their own limitations. Their line of sight is restricted, and their detection range is relatively short. Additionally, they face challenges in identifying the serial number of a drone or differentiating between identical drones, one authorized and the other not. The frequency of false alarms also remains a significant concern.

Electronic signals such as Wi-Fi or radio frequency (RF) signals are used to communicate between a drone and its remote control. By detecting and analyzing these signals, it is possible to determine the presence and location of a drone in the airspace. One significant constraint is that RF scanners share the same limitations as their electro-optical counterparts.

To empower first responders in their mission, it is crucial to explore advanced technologies that overcome these limitations and enhance drone detection capabilities. By harnessing cuttingedge innovations, we can provide first responders with the tools they need to swiftly and accurately identify and neutralize drone threats, ensuring the safety and security of our communities.

When it comes to preventing or stopping the unauthorized or harmful use of drones, various technologies exist but their shortfalls make them problematic in a emergency scenarios.

Jammer signals can potentially interfere with other electronic devices in the area, including communication systems, navigation systems, and emergency services. This can result in unintended disruption of critical services and communication networks. When it comes to first responders or dealing in emergency situations, jammers should be avoided.

While jammers work by blocking RF frequencies, spoofers send fake GPS signals that mimic legitimate ones. Here again, spoofing can create interference with other communication signals and create invisible collateral damage. Therefore, the same recommendation applies.

Laser weapon systems are currently under development in 18 countries. Despite the hype, it's worth mentioning that lasers cannot avoid creating collateral damage as they destroy the drones they are directed at, therefore it is difficult to see how they could become a valid option for most firstresponder user cases, especially in urban environments.

Designed to entangle the target drone and its rotors, nets can be deployed to capture drones in flight. Similarly to lasers, a drone tangled in a net falling from the sky above critical infrastructure or a mass gathering is unideal and should be avoided.

Integrated Counter-drone Solutions - The Only Viable Option for First Responder Operations in Dense Environments

Integrated Counter-Drone Solutions offer an accurate and relible image by accurately locating both the drone and its operator, while effectively filtering out all false alarms. This eliminates operator fatigue, reduces unnecessary costs, prevents confusion and delays in responding to genuine threats, and upholds public trust in the solution's ability to safeguard against drone-related risks. These solutions also provide ample Detection, Tracking, and Identification (DTI) ranges tailored to operational requirements, typically ranging from over 1km to below 5km. With nearreal-time response times of just a few seconds, the effectiveness of Integrated Counter-Unmanned Aircraft System (Counter-UAS) solution is ensured.

These completely autonomous and userfriendly Integrated Counter-Drone Solutions operate seamlessly without the need for 24/7 supervision, or specialized expertise. They can be easily operated by anyone, eliminating the requirement for extensive training over months. Cost reduction encompasses not only the overall price but also factors in training time, ongoing maintenance, support, and lifetime replacement costs, such as software updates, licensing fees, and staff training.

Addressing diverse operational needs, Integrated Counter-Drone Solutions protect facilities, convoys, and large events. They offer remote operation capabilities and centralized management, allowing multiple systems to be controlled from a (potentially remote) single Command and Control (C2) center. Furthermore, they provide:

- Interoperability: Integration with existing security systems, such as cameras, radars, and command and control systems, to deliver comprehensive security solutions as required.

- Authorized Drone List: Recognition of authorized drones, ensuring regulatory compliance, reducing false alarms, and enhancing the user experience by allowing uninterrupted authorized drone operations. First responders can keep on using their own drones for emergency use cases, without any disruption.

- End-to-End Integration: Seamless integration of detection, tracking, and mitigation, eliminating the need for extensive customization and integration efforts.

These solutions can detect and identify unauthorized commercial drones, simultaneously track multiple drones, and locate their remote controls. They also possess the capability to safely override and land the drones in predefined zones, mitigating the risks associated with uncontrolled drone usage. The most advanced solutions are fully autonomous, requiring minimal training to operate. They are lightweight, enabling rapid deployment within minutes or even mounting on vehicles, ensuring readiness whenever needed. This flexibility allows for the protection of permanent or temporary perimeters, protest marches, or convoys.

Unlike traditional Counter-UAS mitigation technologies involving jamming or spoofing, these advanced Integrated Anti-UAS solutions employ protocol analytics technologies that are safe for any environment, be it civilian or otherwise. Key benefits include:

- Non-interference: No disruption to communication or Global Navigation Satellite Systems (GNSS), ensuring vital communication and coordination among crew members during first-response situations.

- Uninterrupted Authorized Drone Usage: Authorized drone serial numbers can be listed in the C-UAS software, allowing them to operate normally while unauthorized drones are detected, tracked, and mitigated.

- Safe Mitigation: Disconnection of drone communication with its remote control, flying the drone to a safe altitude, and either returning it to its designated 'Home' location or safely landing it in a predefined zone, facilitating easy retrieval by the crew.

However, ensuring a relevant and up-todate library of drones will be a crucial challenge to overcome, as the ability to swiftly support new drones entering the market becomes imperative.
