The possibility of increasing flight duration, particularly for small and micro fixed-wing Unmanned Aerial Systems (UAS), is typically hindered by the payload and size of the platform. In maritime missions, Atmospheric Energy Harvesting (AEH) near the Marine Atmospheric Boundary Layer (MABL), is a low-cost solution, with very promising results, that may allow drastic increases in flight duration by...
In this paper, different Guidance and Control (GC) methods for trajectory tracking are analyzed. This effort considers the ongoing research effort regarding wind features characterization and trajectory generation. The investigation of GC methods is contextualized for long duration missions of small Unmanned Aerial Systems (UAS). These are often hampered by the platform characteristics with cost and...
This paper proposes a solution to generate energy-efficient trajectories for small fixed-wing Unmanned Aerial Systems (UAS) to harvest energy available from the surrounding wind mass. The process of generating such trajectories consists of the identification of the wind field and the different wind features such as gusts and/or wind shear in order to generate on a waypoint-to-waypoint basis trajectories...
