FPV Only

Consider a scenario where an unauthorized FPV drone attempting to access the restricted airspace. When the drone operates, a bi-directional connection is established between the drone and its controller. The downlink channel is a video stream sent by the drone to the controller, while the uplink channel carries control commands sent from the controller to the drone. Let’s assume that both channels are encrypted and the drone’s controller is out of the monitoring station’s detection range.

Traditional Detection for FPV

The control channel carries flight commands from the controller to the drone. Overall, the control channel comprises of two different network flows, periodic control packets and heartbeats packets. In case of controllers that receive a video stream over TCP, a flow of acknowledgments (ACKs) will be sent out back to the drone as well. Note that even if ACKs are encrypted, they can be easily identified by the packet size (20 bytes TCP header without options + 20 bytes IP header without payload). Some control applications embed heartbeat messages within the stream of periodic control packets. Both streams (heartbeats and control packets) have rather unique sizes and inter-arrival times. Therefore, a simple detection scheme can easily differentiate between the controller’s traffic and other background traffic.

The issue however comes when the drone controller is not present within the range of the detection system and their traffic cannot be captured and classified. Since the wireless channel is assumed to be encrypted, the standard detection methodology cannot identify drone FPV channels by simply inspecting the content of the intercepted packets. Therefore, the traffic profile of an FPV transmission must be identified based on understanding how video encoding and compression algorithms affect the network traffic pattern of a video streaming application.

A drone’s FPV channel is considered a channel of a video streaming application that transports compressed video frames from the drone to the controller. A video is a stream or a sequence of still pictures. In order to decrease the portion of channel capacity used to transport the video over wireless channels, almost all video encoders include a video compression algorithm.

Roark FPV Detection

Our FPV specific detection which is based on the concept of a pivot; a special packet found in the drone’s FPV traffic which will be utilized as an anchor for building drone features. The Drone Detection Framework is the composition of two main components: a Pivot Extraction Algorithm and a Classification Model . In short, the Pivot Extraction Algorithm takes a sequence of encrypted packets as an input, tracks the packets that belong to video frames based on the video compression analysis, extracts pivot fingerprints, and estimates the size of the pivot packet for each encountered WiFi device. The engine of the Classification Model uses the pivot size to construct a set of FPV features and feeds it to a binary classifier which outputs “YES” if the packets belong to an FPV drone and “NO” otherwise.

Bi-directional RSSI recording is used to accurately predict the drones proximity to the sensor.

Acoustic Detection

The Roark Acoustic detection sensor is an acoustic array that passively detects and tracks class I and II drones using advanced machine learning algorithms. The device has 5 sensor panels, each sensor covers up to a 120-degree field of view, looking for acoustic changes within a network of constantly monitored sectors. Change in any acoustic sector triggers high-resolution acoustic beams that collect the sound of that change. The system then analyzes this information, classifies drones and is able to separate them from any other sounds in the area. As the system is trained on the propeller sound, it will recognize any drone, both current and future fixed and rotary wing systems. Equally important, the algorithm will suppress sound that is not a target and provide close to zero false positives.

Operation and user interface is provided either on a browser enabled network connected device, or through machine-to-machine API interface. Upon positive classification of a drone, the alarm, along with precise bearing to target, is forwarded to the operator screen or to the API-connected system.
