Airborne sensor fusion: Expected accuracy and behavior of a concurrent adjustment

Jan Skaloud, Davide Antonio Cucci, Aurélien Arnaud Brun, Kyriaki Mouzakidou

Tightly-coupled sensor orientation, i.e. the simultaneous processing of temporal (GNSS and raw inertial) and spatial (image and lidar) constraints in a common adjustment, has demonstrated significant improvement in the quality of attitude determination wit ...

Wind Defiant Morphing Drones

Dario Floreano, Charalampos Vourtsis, Victor Casas Rochel, William John Stewart

Intense winds are a challenge for vertical take-off and landing drones with wings. In particular, in the hovering regime, wings are sensitive to wind currents that can be detrimental to their operational and energetic performances. Tail-sitters are particu ...

What determines the attitude-behavior link when voting on renewable energy policies? The roles of problem perception and policy design

Philippe Thalmann

This chapter sheds light on the paradox between the general perception of climate change related problems and resistance to measures addressing it, namely the support of renewable energy policies at the ballot box. Using conjoint analyses, we investigate t ...

Fusion of Photo with Airborne Laser Scanning

Jan Skaloud, Emmanuel Pierre Quentin Clédat

Photogrammetry and Laser-Scanning are usually considered as complementary. Integration of these two observation methods has the potential to blend their individual advantages. The resulting benefit is likely to be higher in drone airborne mapping, which pa ...

Developing Attitude Measures Based on Respondents’ Representations of Unfamiliar Objects

Stéphane Joost, Alain Clémence

A key challenge in the design of effective survey questionnaires is to write questions that respondents can understand consistently. Recommendations in the questionnaire design literature propose the use of respondents’ own terminology to facilitate compre ...

Bundle adjustment with raw inertial observations

Jan Skaloud, Davide Antonio Cucci, Martin Rehak

t is well known that accurate aerial position and attitude control is beneficial for image orientation in airborne photogrammetry. The aerial control is traditionally obtained by Kalman filtering/smoothing inertial and GNSS observations prior to the bundle ...

A Micro Aerial Vehicle with Precise Position and Attitude Sensors

Jan Skaloud, Martin Rehak, Romain Mabillard

This study shows the potential of navigation technologies in the field of position and orientation determination on a micro aerial vehicle (MAV), which weight does not exceed 5 kg. Although the MAV systems feature high flexibility and capability of flying ...

GNSS BASED ATTITUDE DETERMINATION SYSTEMS FOR NANOSATELLITES

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano

Attitude determination systems based on global navigation satellite systems (GNSSs) present several advantages, most of all, for very small satellites. GNSS receivers have low power consumption, limited mass, small volume, and are rel-atively inexpensive. ...
