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 ...

Modeling of Long-Term Multipactor Evolution in Microwave Components Including Dielectric Layers

Apostolos Sounas

Multipactor is a resonant vacuum discharge occurring in microwave components of satellite systems as well as in particle accelerators. Due to its undesirable effects, multipactor analysis constitutes a mandatory step in the design of modern satellite compo ...

Deployment of a tensegrity footbridge

Ian Smith, Nicolas Willy Veuve, Seif Dalil Safaei

Deployable structures are structures that transform their shape from a compact state to an extended in-service position. Structures composed of tension elements that surround compression elements in equilibrium are called tensegrity structures. Tensegritie ...

Space charge effects for multipactor in coaxial lines

Michael Mattes, Francisco Edén Sorolla Rosario, Apostolos Sounas

Multipactor is a hazardous vacuum discharge produced by secondary electron emission within microwave devices of particle accelerators and telecommunication satellites. This work analyzes the dynamics of the multipactor discharge within a coaxial line for t ...

On-Board Human-Aware Navigation for Indoor Resource-Constrained Robots: A Case-Study with the Ranger

Alcherio Martinoli, Zeynab Talebpour, Inaki Navarro Oiza

Introducing simple robotic platforms into domes- tic environments is faced with the challenge of social accept- ability. Therefore human-aware navigation is a must for robots operating in environments shared with human users. In this work, we focus on the ...

Air-ground Matching: Appearance-based GPS-denied Urban Localization of Micro Aerial Vehicles

Davide Scaramuzza

In this paper, we address the problem of globally localizing and tracking the pose of a camera-equipped micro aerial vehicle (MAV) flying in urban streets at low altitudes without GPS. An image-based global positioning system is introduced to localize the ...

Fluctuation-driven neural dynamics reproduce Drosophila locomotor patterns

Dario Floreano, Pavan P Ramdya, Kyle Gustafson, Andrea Maesani

The neural mechanisms determining the timing of even simple actions, such as when to walk or rest, are largely mysterious. One intriguing, but untested, hypothesis posits a role for ongoing activity fluctuations in neurons of central action selection circu ...

Automatic and computationally efficient method for model selection in inertial sensor calibration

Jan Skaloud, Stéphane Guerrier

The identification and selection of a small set of models that are able to well describe and predict the error signals coming from IMU sensors is of utmost importance to improve the navigation precision of these devices. For this reason, in this paper we p ...

Calibration of the GNSS Signal Amplitudes in the Interference Pattern Technique for Altimetry

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix, Mohammed Benjelloun

Global Navigation Satellite Systems signals can be used in bi-static radar systems in order to get altimetric measurements. With a single classic GNSS ground-based receiver processing the combination of the signals coming directly and after one reflection ...
