This document provides supplementary online material for the paper titled “Evolutionary coordination system for fixed-wing communications unmanned aerial vehicles” recently submitted to TAROS 2014. It mainly focuses on critical system components, namely the aerial vehicles kinematics model, link budget management and also addresses the issue of time synchronisation and algorithmic flow.
Stable imaging of an unmanned aerial vehicle (UAV) photogrammetry system is an important issue that affects the data processing and application of the system. Compared with traditional aerial images, the large rotation of roll, pitch, and yaw angles of UAV images decrease image quality and result in image deformation, thereby affecting the ground resolution, overlaps, and the consistency of the...
Unmanned aerial systems (UAS), commonly referred to as drones, are finding applications in several ecological research areas since remotely piloted aircraft (RPA) technology has ceased to be a military prerogative. Fixed-wing RPA have been tested for line transect aerial surveys of geographically dispersed marine mammal species. Despite many advantages, their systematic use is far from a realit...
In this paper we address the alignment of historical and present-day aerial photographs. Historical images refer to regions bombed during the second world war. In this regions the risk of unexploded bombs is still high, especially where the bombing were more frequent. The alignment is required to fill-in an unexploded bombs risk map. The task is challenging because a lot of features in the hist...
