VDM-based navigation for Delta-wing UAVs: Models, calibration, implementation
Autonomous navigation of small UAVs is typically based on the integration of inertial navigation systems (INS) together with global navigation satellite systems (GNSS). However, GNSS signals can face various forms of interference affecting their continuous ...
EPFL2024VDMNav: Software Architecture for Aerodynamically Constrained Navigation on Small Fixed-Wing Drones
Jan Skaloud, Gabriel François Laupré
Navigation of drones is predominantly based on sensor fusion algorithms. Most of these algorithms make use of some form of Bayesian filtering with a majority employing an Extended Kalman Filter (EKF), wherein inertial measurements are fused with a Global N ...
2024Aerodynamic modeling of a delta-wing UAV for model-based navigation
Jan Skaloud, Pasquale Longobardi
This study aims to identify an optimal, as well as practical, parametric structure for a delta-wing UAV aerodynamic model for the purpose of model-based navigation. We present a comprehensive procedure for characterizing the aerodynamics of this platform, ...
2024Identifying aerodynamics of small fixed-wing drones using inertial measurements for model-based navigation
Jan Skaloud, Gabriel François Laupré
The success of drone missions is incumbent on an accurate determination of the drone pose and velocity, which are collectively estimated by fusing iner- tial measurement unit and global navigation satellite system (GNSS) mea- surements. However, during a G ...

2023Calibration of Fixed-Wing UAV Aerodynamic Coefficients with Photogrammetry for VDM-based Navigation
Jan Skaloud, Gabriel François Laupré
Autonomous navigation is a crucial aspect for fixed-wing unmanned aerial vehicle operation when encountering disturbance or denial of GNSS signal reception. Vehicle dynamic model-based navigation improves the performance of methods based exclusively on int ...
2021X-ray pulsar-based GNC system for formation flying in high Earth orbits
Volker Gass, Camille Sébastien Pirat
In this paper, comprehensive pulsar-based Guidance, Navigation and Control (GNC) system is designed and applied to satellites formation flying. The complete autonomy of the X-ray pulsar navigation technology provides both absolute and relative positioning ...
PERGAMON-ELSEVIER SCIENCE LTD2020Doppler-based positioning using LEO augmented satellite constellation - Simulations of perspectives
The Global Navigation Satellite System (GNSS) refers to a constellation of satellites emitting signals from space, used to provide Position, Navigation and Timing (PNT) services to the receivers on Earth. Nowadays, the GNSS is exploited in a wide range of ...
2020Calibration Aspects of INS Navigation
The use of a Bayesian filter (e.g., Kalman filter) for the fusion of information from satellite positioning and inertial navigation is a common approach in many applications, where the knowledge of position, velocity, and attitude in space are of great int ...
EPFL2019Sensitivity to Time Delays in VDM-Based Navigation
Jan Skaloud, Gabriel François Laupré, Mehran Khaghani
A recently proposed navigation methodology for aerial platforms based on the vehicle dynamic model (VDM) has shown promising results in terms of navigation autonomy. Its practical realization requires that control inputs are related to the same absolute ti ...
