High accuracy GNSS based navigation in GEO

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano, Paul David Blunt, Endrit Shehaj

Although significant improvements in efficiency and performance of communication satellites have been achieved in the past decades, it is expected that the demand for new platforms in Geostationary Orbit (GEO) and for the On-Orbit Servicing (OOS) on the ex ...

Architecture-based Design: A Satellite On-board Software Case Study

Simon Bliudze, Joseph Sifakis, Anton Ivanov, Anastasia Mavridou

In this case study, we apply the architecture-based design approach to the control software of the CubETH satellite. Architectures are a means for ensuring global coordination properties and thus, achieving correctness of complex systems by construction. T ...

Study of laser-pumped double-resonance clock signals using a microfabricated cell

Nico de Rooij, Yves Pétremand

We present our microwave spectroscopic studies on laser-microwave double-resonance (DR) signals obtained from a micro-fabricated Rb vapor cell. This study focuses on the characteristics and systematic shifts of the ground-state 'clock transition' in Rb-87 ...

Long Term Real Trajectory Reuse Through Region Goal Satisfaction

Pascal Fua, Daniel Thalmann, Ronan Boulic, Stéphane Gobron, Mirko Raca, Junghyun Ahn, Horesh Beny Ben Shitrit, Quentin Silvestre

This paper is motivated by the objective of improving the realism of real-time simulated crowds by reducing short term collision avoidance through long term anticipation of pedestrian trajectories. For this aim, we choose to reuse outdoor pedestrian trajec ...

Ant-based Swarming with Positionless Micro Air Vehicles for Communication Relay

Dario Floreano, Jean-Christophe Zufferey, Sabine Hauert

Swarming without positioning information is interesting in application- oriented systems because it alleviates the need for sensors which are dependent on the environment, expensive in terms of energy, cost, size and weight, or unusable at useful ranges fo ...
