An Unmanned Aerial System (UAS) is an uninhabited airplane, piloted by embedded avionics and supervised by an operator on ground. Unmanned Aerial Systems were designed to operate in dangerous situations, like military missions. With the avionics technological evolution, Unmanned Aerial Systems also become a valid option for commercial applications, specially for dull and tedious surveillance ap...

In this work an automated traffic analysis in aerial image sequences recorded by an unmanned aerial vehicle (UAV) has been developed, which provides the trajectories of the vehicles especially during overtaking. Methods of photogrammetry and image processing are used to detect the vehicles and to determine and track their positions. Camera calibration is necessary in order to transform image co...

Rapid present development of unmanned aerial vehicles is rather unstructured. Starting from general systems theory we formulate classification of unmanned aerial vehicles (UAVs) that properly groups diverse produced unmanned aerial vehicles, along with their currently unproduced, yet possible types. First we structure the context of applications of UAVs using systems thinking. Secondly, we divi...

Irrigated row-crop agriculture is contributing to declining groundwater in areas such as the Mississippi Delta region of eastern Arkansas. There is a need to move toward sustainable levels of groundwater withdrawal. Recent improvements in remote monitoring technologies such as wireless soil moisture sensors and unmanned aerial vehicles offer the potential for farmers to effectively practice sit...

This paper presents an idea-phase introduction of a tactical level communication system (battalion and below). The introduced communication system utilizes Unmanned Aircraft Systems to ensure the message throughput and to receive and transmit large quantities of data requiring wide bandwidth. The introduced communication system enables utilizing different waveforms and frequencies when communic...
