The unsteady and nonlinear aerodynamic characteristics of the Meridian unmanned aerial system in the presence of wind shear are investigated using the recorded test data during flights in Polar Regions. The Meridian UAS is designed to provide an aerial platform for ice-penetrating radar developed for research in Polar Regions. The Meridian Unmanned Aerial Vehicle (UAS) is a 499 kg (1,100 pounds...

This thesis presents the system architecture for landing an Unmanned Aerial Vehicle (UAV) from a hovering position without the intervention of a human operator. Through the use of feedback information from a height sensor, the UAV is commanded to perform controlled descent with the desired landing parameters by implementation of the flight control laws. The plant model of the system was determi...

The use of a UAS (Unmanned Aircraft System) was tested to survey large mammals in the Nazinga Game Ranch in the south of Burkina Faso. The Gatewing ×100™ equipped with a Ricoh GR III camera was used to test animal reaction as the UAS passed, and visibility on the images. No reaction was recorded as the UAS passed at a height of 100 m. Observations, made on a set of more than 7000 images, reveal...

During recent years there has been growing interest in unmanned aerial vehicles (UAVs). Moreover, the necessity to control and navigate these vehicles has attracted much attention from researchers in this field. This is mostly due to the fact that the interactions between turbulent airflows apply complex aerodynamic forces to the system. Since the dynamics of a quadrotor are non-linear and the ...

This project describes the implementation of a BDI architecture for solving problems of collaboration and coordination among aerial mobile robots used through Unmanned Aerial Vehicle (UAV). A Multi-Agent System is implemented in people search and it is developed on Jason software.The benefits of developing this model is diverse such as optimizing the collaborative work among intelligent agents ...

Communication networks and strategies for cooperative UAV swarms have received significant attention. The main problem in controlling autonomous vehicles needs some knowledge of its altitude angles. These angles can be measured in different ways, for instance, using a conventional inertial navigation system. A novel approach to deal these problems by modern Micro electro mechanical systems (MEM...
