Optimal deployment of unmanned aerial vehicles (UAVs) as communication relays is studied for fixed-rate variable-power systems. The considered setup is a set of ground transmitters (GTs) wishing to communicate with a set of ground receivers (GRs) through the UAVs. Each GT-GR pair communicates through only one selected UAV and have no direct link. Two different UAV selection scenarios are studie...

-UAV (unmanned aerial vehicle) has been widely used in both military and civilian fields in recent years. With the development of UAV, high quality training for the UAV operators on the ground is necessary and urgent, the fidelity of simulation training system is very important, the fidelity training system can simulate the flying environment on the sky, the flying simulation software is the co...

Unmanned Aerial Vehicles (UAV) enable the in-depth reconnaissance and surveillance of major incidents. Uncontrolled emissions of liquid or gaseous contaminants in cases of volcanic eruptions, large fires, industrial incidents or terrorist attacks can be analyzed by utilizing UAV. Hence, the use of cognitive Unmanned Aerial Systems (UAS) for distributing mobile sensors in incident areas is in ge...

In this paper, we present control systems for an unmanned aerial vehicle (UAV) which provides aerial support for an unmanned ground vehicle (UGV). The UGV acts as a mobile launching pad for the UAV. The UAV provides additional environmental image feedback to the UGV. Our UAV of choice is a Parrot ArDrone 2.0 quadcopter, a small four rotored aerial vehicle, picked for its agile flight and video ...

The past few years have witnessed a tremendous increase on the use of unmanned aerial vehicles (UAVs) in civilian applications, which increasingly call for high-performance communication between UAVs and their ground clients, especially when they are densely deployed. To achieve this goal, cellular base stations (BSs) can be leveraged to provide a new and promising solution to support massive U...

The theory and practice of unmanned aerial vehicle (UAV) capture and control via Global Positioning System (GPS) signal spoofing are analyzed and demonstrated. The goal of this work is to explore UAV vulnerability to deceptive GPS signals. Specifically, this paper (1) establishes the necessary conditions for UAV capture via GPS spoofing, and (2) explores the spoofer’s range of possible post-cap...

Despite the name Unmanned Aerial Vehicle (UAV), humans are integral to UAV operations. Since the UAV’s operator interface is the primary facilitator of human-vehicle communication and coordination, an effectively designed interface is critical for successful UAV operations. To design an effective interface, it is essential to first determine the information needs for both the human and UAV comp...

Unmanned aerial vehicles (UAVs) are an emerging technology with the potential to revolutionize commercial industries and the public domain outside of the military. UAVs would be able to speed up rescue and recovery operations from natural disasters and can be used for autonomous delivery systems (e.g., Amazon Prime Air). An increase in the number of active UAV systems in dense urban areas is at...

The development and final system architecture of the Missouri S&T AESS UAV Team UAV is described. The project follows the guidelines for the 2008 UAV Challenge – Outback Rescue which is an international aerospace competition held in Kingaroy, Australia. The design of the electrical subsystems and the overall architecture of the UAV is described. The selected systems are integrated into a standa...

Using base stations mounted on an unmanned aerial vehicle (UAV-BSs) is a promising new evolution of wireless networks for the provision of on-demand high data rates. While many studies have explored deploying UAV-BSs in a green field —no existence of terrestrial BSs (T-BSs), this paper focuses on the deployment of UAV-BSs in the presence of a terrestrial network. The purpose of this article is ...
