The present invention relates to apparatus for providing surveillance and bi-directional communication capabilities to unmanned aircraft systems.
Small Unmanned Aircraft Systems (sUASs), commonly known as drones, have the potential to enable a broad range of capabilities for tactical operators across a wide array of missions and environments. However, many drones marketed towards law enforcement organizations (LEOs) are made for outdoor, search-and-rescue style mission sets, and therefore are not equipped with sensors and payloads suitable for more sophisticated reconnaissance and tactical missions. In addition, traditional drones for law enforcement are often large, expensive, and require a significant amount of operator training; and many have ground control systems that are not easily man-portable.
Commercial drones are relatively inexpensive with relatively good flight performance. However, existing commercial drones provide relatively limited policing, peacekeeping, and surveillance capabilities. While commercial drones may be modified to improve such capabilities, these modifications may be relatively expensive and may negatively affect the performance parameters of the drone. Further, modifications must be made individually to each drones, which is time consuming and expensive.
A need arises for techniques by which additional capabilities may be added to existing drones, with little or no modification of the drone required.
Embodiments of the present systems and methods may provide the capability to add capabilities to existing drones, with little or no modification of the drone itself.
For example, in an embodiment, apparatus for enhancing operation of an unmanned aircraft system may comprise a controller comprising a processor, memory, and program instructions stored in the memory and executable by the processor, lighting apparatus controllable by the processor, audio apparatus controllable by the processor, communication circuitry communicatively connected to the controller to provide communication between the apparatus and an operator, and a power source, wherein the apparatus is adapted to be mounted to an unmanned aircraft system and to operate independently of the unmanned aircraft system.
In embodiments, the lighting apparatus may comprise illumination lighting devices and distraction/diversion lighting devices. The illumination lighting devices may comprise at least one of: at least one wide-beam visible light LED lamp and at least one infrared LED lamp and the distraction/diversion lighting devices comprise at least one of: at least one narrow-beam colored LED lamp and at least one wide-beam LED lamp operating in a strobing mode. The audio apparatus may comprise at least one microphone and at least one speaker. The at least one microphone may comprise at least one omni-directional microphone and at least one directional microphone. The audio apparatus may be adapted to provide at least one of: bi-directional communication between the operator and a subject and audible distraction.
In an embodiment, a system may comprise an unmanned aircraft system comprising an apparatus mounted to the unmanned aircraft system and independently operable from the unmanned aircraft system, the apparatus may comprise a controller comprising a processor, memory, and program instructions stored in the memory and executable by the processor, lighting apparatus controllable by the processor, audio apparatus controllable by the processor, communication circuitry communicatively connected to the controller to provide communication between the apparatus and a control device, and a power source, and a control device comprising a processor, memory, and program instructions stored in the memory and executable by the processor to provide a user interface for controlling the apparatus and communications with the apparatus.
The details of the present invention, both as to its structure and operation, can best be understood by referring to the accompanying drawings, in which like reference numbers and designations refer to like elements.
Embodiments of the present systems and methods may provide the capability to add capabilities to existing UASs, with little or no modification of the UAS itself.
Embodiments of the present systems and methods may provide a solution to fill the need for a capable, cost-effective UAS for use in, for example, tactical situations. In embodiments, the present systems and methods may provide the capability to quickly capture, process, and distribute audio and video data to support tactical operations and decision making in a variety of environments and situations, as well as providing communication, tactical distraction and operational mapping capabilities.
Embodiments of the present systems and methods may provide audio sensors, radios, speakers, and emitters designed for audio surveillance and/or bi-directional communication with a target. Additional features may provide low-light video and photography operations. A tactical distraction mode may give operators the edge when engaging a perpetrator. The combined package gives tactical teams ultimate flexibility during all phases of operations.
Embodiments of the present systems and methods may utilize commercially available drones, such as the DJI™ Mavic Pro, which may lower the initial cost of the system, thereby reducing the financial risks and allowing greater flexibility in system employment.

Control device 106 may be used to control drone 104 as well as accessory payload 102 using a custom app or using a web app. In either case, the app may provide intuitive drone control and aerial data capture and delivery, designed to help drone users react quickly to changing conditions. The app may feature an intuitive drag-and-drop mission planning, auto takeoffs and landings, and point-to-point navigation that put the operator in complete control according to FAA guidelines. During flight, the app may display radio signal strength, 3D position, and various other flight information from drone 104. When used in conjunction with the drone 104 manual controller, the app can display real-time video and still images to provide instant information from a scene or operation. The app may feature cloud-based data processing, distribution and storage. It may photostitch individual image files into high-definition 2D orthomosaics and 3D models, sync the processed data to common industry software, distribute it to colleagues, store and index files according to date and worksite, and be used to markup and annotate files online.
An exemplary block diagram of an accessory payload 102 is shown in
Base station 214 may include or be connected to wireless radio frequency transceiver circuitry, for transmitting and receiving communications and control signals wirelessly with accessory payload 102.

Microphone array 206 may include one or more directional or omni-direction microphones for receiving sounds audible in the vicinity of the drone 104 to which accessory payload 102 is attached. Speaker 208 may include one or more speakers for transmitting sounds to the vicinity of the drone 104 to which accessory payload 102 is attached. Microphone array 206 and speaker 208 may be connected to controller 202 through analog and digital circuitry that may provide the capability to convert received digital signals into audio signals for transmission by speaker 208 and to convert audio signals from microphone array 206 to digital signals for transmission. Lighting 210 may include light sources, such as LED lamps to provide illumination, or additional illumination.
An exemplary schematic diagram of accessory payload 102 is shown in
In embodiments, microphone array 206 may include an omni-directional microphone 304 with noise-cancelling filters for capturing surround-sound audio from a site or crime scene while blocking the hum from drone motors and propellers. In embodiments, omni-directional microphone 304 may be mounted at the top of accessory payload 102 in order to enhance the omni-directional characteristics of the microphone. Microphone array 206 may also include a directional microphone 306 with noise filters for collecting more targeted audio from a specific location or individual. In embodiments, directional microphone 306 may be mounted at the front of accessory payload 102 in order to enhance the directional characteristics of the microphone. Speaker 208 may provide bi-directional communication between the operator using control device 106 and the subject under surveillance when traditional means of long-distance communication like phone or two-way radio are unavailable, or when otherwise desired. Further, speaker 208 may provide audible distraction of individuals and/or groups.
Accessory payload 102 may provide daylight and low-light photo and video surveillance capabilities. For example, typical drones include standard cameras. Accessory payload 102 may include lighting 210 to provide illumination, or additional illumination. In embodiments, lighting 210 may include illumination lighting 308, for example, one or more superbright LEDs to provide adequate light in any after-dark situation. In embodiments, illumination lighting 308 may include one or more Infrared (IR) LEDs to provide a light source that is imperceptible to the human eye and night-vision-like photo and video collection. In embodiments, lighting 210 may include distraction lighting 310, for example, one or more LEDs that may provide visual distraction of individuals and/or groups. In embodiments, the LEDs may be red, or other color, narrow beam LEDs that may be aimed at particular individuals. The LEDs may be high-intensity, narrow-beam, red LEDs that may be aimed to distract or disorient a person without blinding. This distraction feature may be used prior to approaching or engaging a target at critical stages of a standoff or other tactical operation. It is to be further noted, that, in embodiments, illumination lighting 308 may also be strobed in order to provide visual distraction or diversion of individuals and/or groups
In embodiments, further features of accessory payload 102 may include:
LOW-POWER OPERATION—Accessory payload 102 may operate independently from the main battery and power supply of the drone. Running on its own battery power, for example, a single, lightweight CRI23A 3V battery, accessory payload 102 may provide audio and video surveillance, bi-directional communication, illumination and tactical distraction at varying intervals for operations lasting more than 30 minutes.
TACTICAL MAPPING OPERATIONS—Accessory payload 102, in conjunction with the drone may provide the capability of quickly producing high-quality overhead maps and 3D models for use in tactical mission planning and execution. These maps may be imported into a variety of mapping and planning tools for integration with existing workflows.
INDOOR AND OUTDOOR OPERATIONS—The drone may typically be designed for both indoor and outdoor operations. It may fly GPS-guided pre-planned missions, as well as indoors using precision station-keeping cameras and manual controls through the bundled controller. The software system may allow users to pre-plan missions, as well as monitor the drone during manual flight operations.
LOWER SYSTEM COSTS—By creating a single upgrade module for an existing, affordable, commercially available drone, accessory payload 102 may reduce the acquisition costs to adopt this technology. A complete tactical operations package may be provided, including a mapping and modeling platform on a drone that can be used both indoors and outdoors. This means less equipment and user training, further reducing costs and time for implementation.
