Unmanned Aerial Vehicles (UAVs), or drones, have recently emerged as a relatively affordable and accessible method for studying wildlife. Vertical Take-off Landing (VTOL) UAVs are appropriate morphometric, behavioural, abundance demographic studies of marine mammals, providing stable, nonintrusive highly manoeuvrable platform. Previous using VTOL been conducted on various mammal species, but sp...

Unmanned Aerial Vehicles (UAVs) are now becoming increasingly accessible to amateur and commercial users alike. An air traffic management (ATM) system is needed help ensure that this newest entrant into the skies does not collide with others. In an ATM, airspace can be composed of airways, intersec...

Trajectory tracking and connguration stabilization for the VTOL aircraft (vertical take oo and landing) in the literature has been only considered for the case of slight or zero input coupling. In this paper, our main contribution is to address global connguration stabilization for the VTOL aircraft with a strong input coupling using a smooth static state feedback.

Trajectory tracking and configuration stabilization for the vertical takeoff and landing (VTOL) aircraft has been so far considered in the literature only in the presence of a slight (or zero) input coupling (i.e., for a small ). In this note, our main contribution is to address global configuration stabilization for the VTOL aircraft with a strong input coupling using a smooth static state fee...

In this paper, an unmanned aerial vehicle (UAV) assisted cooperative communication system is studied, wherein a source transmits information to the destination through an energy harvesting decode-and-forward UAV. It is assumed that the UAV can freely move in between the source-destination pair to set up line of sight communications with the both nodes. Since the battery of the UAV may be limite...

The application scope of unmanned aerial vehicles (UAVs) is increasing along with commensurate advancements in performance. hybrid quadrotor vertical takeoff and landing (VTOL) UAV has the benefits both rotary-wing aircraft fixed-wing aircraft. However, vehicle requires a robust controller for takeoff, landing, transition, hovering modes because aerodynamic parameters differ those modes. We con...

This paper addresses the trajectory tracking problem for a remotely controlled quadrotor vertical take off and landing aircraft (VTOL), under the restriction that only the inertial coordinates are available for measurement. The problem is solved in two steps: first, a discretetime local exponential observer is designed which allows estimating the roll and pitching angles as well as all the velo...
