CLEARSKY Drone Threat Management

Unmanned Aerial Vehicles (UAVs) have the capability to disrupt entire communications systems, business operations and cause catastrophic damage. 24×7 situational intelligence regarding these threats is critical to protect: National borders, major cities and critical assets and large public venues.

Multiple technologies, working in unison around the clock, are required to provide the level of protection required against these threats.

Although the majority of commercial UAVs operate in 2.4 and 5.8 MHz frequencies, drones can operate in any area of the spectrum. With slight modifications, multiple forms of communication can also be utilized for command and control (e.g., cellular). This makes wideband, automated signal recognition a foundational requirement for Drone Threat Management and Critical Asset Protection.

DGS CLEARSKY™ monitors from 40 MHz to 6 GHz, covering the standard communications spectrum utilized for command, control and reconnaissance of commercial UAVs.

Drone Monitor, Track & Classify

A major component required in any drone detection system involves automatic RF recognition and classification. The ability to identify a drone’s presence quickly enables appropriate responses prior to catastrophic damage.

DGS automatic detection and analysis capabilities enable the system to instantaneously perform locational direction finding and match drone profiles.

Signal Characterization Engines

Provide valuable information such as:

  • Location Information/Direction
  • Manufacturer Name
  • Drone Type
  • MAC Address

Actionable information enables swift resolution.

  • Long distance detection – Up to 2 km.
  • Speed of classification – Drones are detected and categorized using state-of-the-art machine learning, typically in under 2 seconds.
  • Easily integrated with 3rd party systems (radar, camera systems, etc.)
  • Wideband scanning- Detection anywhere from 40 MHz to 6 GHz.
  • Line of bearing to both drone and controller.

Drone Defend:

Drone intercession technologies typically focus on the RC link. The vast majority of drones are designed with a fail-safe protocol when communication with the operator is lost:

  1. Return to home (GPS location at launch) is the most common behavior.
  2. Descend gradually in place (controlled landing).

Because DGS CLEARSKY™ provides location information for both the drone and the operator, authorities can stop the drone from advancing while also locating the operator.

Many drones utilize advanced frequency hopping and encryption that will render some vendors’ counter-UAS systems ineffective. Additionally, some vendors require demodulation of the drone control protocol before classifying and defeating the drone. This demodulation takes valuable time, sometimes up to 30 seconds, allowing a high-speed drone to get too close to the protected asset or event. DGS CLEARSKY™ uses advanced machine learning to classify the drone signal, typically in under 2 seconds. This extra time, coupled with DGS long-distance detection, allows the drone to be stopped before it enters protected airspace.

DGS provides additional capabilities, subject to local regulatory restrictions, for disabling the first-person video of a drone, thereby forcing the operator to engage automatic return-to-home, and for disabling the drone’s GPS reception, which is useful for pre-programmed waypoint drones without an active operator.

Please note that regulatory restrictions for drone defend vary from country to country. DGS is actively involved in counter-UAS legislation and will adhere to current regulations.
