Mission Design and GNC for In-Orbit Demonstration of Active Debris Removal Technologies with CubeSats

Volker Gass, Muriel Richard, Camille Sébastien Pirat, Federico Belloni, Reto Wiesendanger, Christophe Dominique Paccolat

Within the frame of the ESA’s General Support Technology Programme, EPFL studied two In-Orbit Demonstration (IOD) missions using CubeSat technologies. These IODs aim at alleviating the technical risk inherent to new technologies required for Active Debris ...

ACTIVE MODEL ROCKET STABILIZATION VIA COLD GAS THRUSTERS

Gautier Marie Pierre Rouaze, Anton Ivanov, Xavier Collaud, Raimondo Pictet, Danylo Malyuta, Mikael Martins Gaspar

This paper describes the development and testing of a reaction control system (RCS) for a model rocket named FALCO-4. The rocket uses cold gas jets to keep itself perfectly vertical at low speeds. We first describe the mechanical layout of FALCO-4 and the ...

A Bayesian Approach for Pervasive Estimation of Breaststroke Velocity Using a Wearable IMU

Kamiar Aminian, Grégoire Millet, Farzin Dadashi

An ubiquitous assessment of swimming velocity (main metric of the performance) is essential for the coach to provide a tailored feedback to the trainee. We present a probabilistic framework for the data-driven estimation of the swimming velocity at every c ...

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. ...

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 ...

A robotic platform for lower limb optical motion tracking in open space

Hannes Bleuler, Mohamed Bouri, Jeremy Olivier, Amalric Louis Ortlieb

Characterization of gait is largely used for research on locomotion or for clinical improvement and follow up. There exists two main technologies for measurement of the kinematics of walking: IMU systems and optical tracking. Inertial measurement units are ...

Probing Absolute Spin Polarization at the Nanoscale

Klaus Kern, Markus Etzkorn, Matthias Alexander Eltschka, Maximilian Assig

Probing absolute values of spin polarization at the nanoscale offers insight into the fundamental mechanisms of spin-dependent transport. Employing the Zeeman splitting in superconducting tips (Meservey-Tedrow-Fulde effect), we introduce a novel spin-polar ...
