Improving the accuracy of low-cost GNSS by fusion with inertial and magnetic sensors in alpine ski racing

Kamiar Aminian, Benedikt Fasel

For analysing performance in alpine ski racing, an accurate estimation of the skier’s centre of mass trajectory and speed is indispensable. However, the sole use of low-cost GNSS might not be accurate enough to detect meaningful differences. The aim of thi ...

Instrumented shoes for daily activity monitoring in healthy and at risk populations

Christopher Moufawad El Achkar

Daily activity reflects the health status of an individual. Ageing and disease drastically affect all dimensions of mobility, from the number of active bouts to their duration and intensity. Performing less activity leads to muscle deterioration and furthe ...

Autonomous and non-autonomous dynamic model based navigation system for unmanned vehicles

Jan Skaloud, Mehran Khaghani

A navigation system including a vehicle dynamic model (VDM) that serves as the main process model within a navigation filter is described. When used in an unmanned aerial vehicle (UAV), the navigation system may work in communication with inertial measurem ...

Autonomous Vehicle Dynamic Model-Based Navigation for Small UAVs

Jan Skaloud, Mehran Khaghani

This paper presents a novel approach to autonomous navigation for small UAVs, with no extra sensor added to the conventional INS/GNSS setup. The proposed method significantly increases the accuracy and reliability of autonomous navigation, especially for s ...

An analysis of a gyro-free inertial system for INS/GNSS navigation

Mehran Khaghani, Davide Antonio Cucci

Although the concept of determining angular velocity out of the readings of multiple, displaced accelerometers is not new, apparently it has not yet matured into practical technologies. A new generation of low-cost MEMS accelerometers, which is expected to ...

A method for ego-motion estimation in micro-hovering platforms flying in very cluttered environments

Dario Floreano, Jean-Christophe Zufferey, Adrien Briod

We aim at developing autonomous miniature hovering flying robots capable of navigating in unstructured GPS-denied environments. A major challenge is the miniaturization of the embedded sensors and processors that allow such platforms to fly by themselves. ...
