Long-Duration Fully Autonomous Operation of Rotorcraft Unmanned Aerial Systems for Remote-Sensing Data Acquisition
Danylo Malyuta, Christian Brommer, Daniel Hentzen +3
Recent applications of unmanned aerial systems (UAS) to precision agriculture have shown increased ease and efficiency in data collection at precise remote locations. However, furt…
Disturbance Estimation and Rejection for High-Precision Multirotor Position Control
Daniel Hentzen, Thomas Stastny, Roland Siegwart +1
Many multirotor Unmanned Aerial Systems applications have a critical need for precise position control in environments with strong dynamic external disturbances such as wind gusts…
On Flying Backwards: Preventing Run-away of Small, Low-speed, Fixed-wing UAVs in Strong Winds
Thomas Stastny, Roland Siegwart
Small, low-speed fixed-wing Unmanned Aerial Vehicles (UAVs) operating autonomously, beyond-visual-line-of-sight (BVLOS) will inevitably encounter winds rising to levels near or exc…
L1 guidance logic extension for small UAVs: handling high winds and small loiter radii
Thomas Stastny
L1 guidance logic is one of the most widely used path following controllers for small fixed-wing unmanned aerial vehicles (UAVs), primarily due to its simplicity (low-cost implemen…
Free LSD: Prior-Free Visual Landing Site Detection for Autonomous Planes
Timo Hinzmann, Thomas Stastny, Cesar Cadena +2
Full autonomy for fixed-wing unmanned aerial vehicles (UAVs) requires the capability to autonomously detect potential landing sites in unknown and unstructured terrain, allowing fo…
