Uas Detection And Negation, Houbing Song, Yongxin Liu, Jian Wang

Publications

Unauthorized operation of a UAV may present privacy or security risks. A software-defined radio (SDR) or other receiver can be used to monitor a specified range of frequencies to provide detection of wireless communication signals suspected of relating to UAV operation. A protocol detector corresponding to a trained classifier can be applied to data packets demodulated by the SDR. A transmitter can then be triggered to provide warnings by injecting warning data into a video channel in response to the detected protocol. Control of the UAV can be established by transmitting simulated control commands that overwhelm the signals received from …

Unmanned Aerial Systems: Research, Development, Education & Training At Embry-Riddle Aeronautical University, Michael P. Hickey

Publications

With technological breakthroughs in miniaturized aircraft-related components, including but not limited to communications, computer systems and sensors, state-of-the-art unmanned aerial systems (UAS) have become a reality. This fast-growing industry is anticipating and responding to a myriad of societal applications that will provide new and more cost-effective solutions that previous technologies could not, or will replace activities that involved humans in flight with associated risks.

Embry-Riddle Aeronautical University has a long history of aviation-related research and education, and is heavily engaged in UAS activities. This document provides a summary of these activities, and is divided into two parts. The first part …

Ten Years Of The Real World Design Challenge, Robert W. Deters, Brent Terwilliger, S.C. Kleinke, Ralph K. Coppola, Jeff Coppola

Publications

Preparing students to be successful in STEM careers is important to foster continued growth in the US and the world. The Real World Design Challenge is a high school design competition focused on the area of aviation. Students work in teams to solve a real world problem using professional tools. The 2018 challenge marks the tenth anniversary of this program. The first students to compete in this competition are now in the work force. This paper describes the background of RWDC, the different challenges that have been used throughout its ten years, the current precision agriculture challenges using UAS, and …

Wide-Scale Small Unmanned Aircraft System Access To The National Airspace System, John Robbins, Brent Terwilliger, David Ison, Dennis Vincenzi

Publications

Expected revisions of federal policies and regulations for the operation and certification of small unmanned aircraft systems (sUAS) are anticipated to significantly increase the volume of traffic in the National Airspace System (NAS). By investigating critical needs of regulatory compliance and safety, as well as new advancements, it may be possible to identify strategies to address the most pressing concerns of sUAS integration. Findings and recommendations from this research are presented to highlight implications and possible solutions to urgent needs of UAS stakehold-ers, including industry, government, and academia.

Low Speed Re-Fuelling Of Unmanned Aerial Vehicles Using The Drogue System, Ian R. Mcandrew, Elena Navarro

Publications

Unmanned Aerial Vehicles (UAV) are being required to be used in more and more complex situations with larger payloads for extended periods of time. Increasing the expectations and operating ceiling requires increased amounts fuel, that thus limits the potential payloads. This dichotomy has led to the quest for more fuel efficient UAVs; however, when designs are improved then their expectations are increased further. In manned aircraft this can be achieved by in-flight re-fuelling. This research is focused on the process of re-fuelling a UAV at low speeds and the aerodynamics considerations and problems it potentially brings. Practical conclusions to these …
