Ultrafast optical ranging using microresonator soliton frequency combs

Tobias Kippenberg, Maxim Karpov, Martin Hubert Peter Pfeiffer, Arne Kordts

Light detection and ranging is widely used in science and industry. Over the past decade, optical frequency combs were shown to offer advantages in optical ranging, enabling fast distance acquisition with high accuracy. Driven by emerging high-volume appli ...

Stellar-to-halo mass relation of cluster galaxies

Jean-Paul Richard Kneib, Huanyuan Shan

In the formation of galaxy groups and clusters, the dark matter haloes containing satellite galaxies are expected to be tidally stripped in gravitational interactions with the host. We use galaxy-galaxy weak lensing to measure the average mass of dark matt ...

Breathing dissipative solitons in optical microresonators

Tobias Kippenberg, Maxim Karpov, Hairun Guo, Erwan Guillaume Albert Lucas

Dissipative solitons are self-localized structures resulting from a double balance between dispersion and nonlinearity as well as dissipation and a driving force. They occur in a wide variety of fields ranging from optics, hydrodynamics to chemistry and bi ...

Derivation of the Cramér-Rao Bound in the GNSS-Reflectometry Context for Static, Ground-Based Receivers in Scenarios with Coherent Reflection

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

The use of the reflected Global Navigation Satellite Systems’ (GNSS) signals in Earth observation applications, referred to as GNSS reflectometry (GNSS-R), has been already studied for more than two decades. However, the estimation precision that can be ac ...

An Efficient Time-frequency Algorithm for the Weak Signal Acquisition of Modernized GNSS Signals

Pierre-André Farine, Cyril Botteron, Jérôme Leclère, Vincenzo Capuano, Jia Tian, Yanguang Wang

The new GPS/Galileo/Compass signals use much longer code lengths and higher code frequencies than the GPS L1 C/A signal. As a result, they can provide improved ranging and anti-jamming performances. Unfortunately, their acquisition complexity is significan ...

CubETH: low cost GNSS space experiment for precise orbit determination

Volker Gass, Louis Antoine Masson, Anton Ivanov, Federico Belloni, Reto Wiesendanger, Stefano Rossi

CubETH is a project to evaluate and demonstrate possibilities of low-cost GNSS receivers on a nano-satellite by following the Cubesat standard. The development of this new Swiss cubesat mission is underway at the Swiss Polytechnical Schools, launch is plan ...

Automated approach for rigorous light detection and ranging system calibration without preprocessing and strict terrain coverage requirements

Jan Skaloud

Light detection and ranging (LiDAR) has demonstrated its capabilities as a prominent technique for the direct acquisition of high density and accurate topographic information. To achieve the potential accuracy of such systems, a rigorous system calibration ...

AUTOMATIC MAPPING FROM ULTRA-LIGHT UAV IMAGERY

Pascal Fua, Christoph Strecha, Olivier Küng

This paper presents an affordable, fully automated and accurate mapping solutions based on ultra-light UAV imagery, which is commercialized by Pix4D. We show interesting application in the field of UAV mapping, analyse the accuracy of the automated process ...

On Secure and Precise IR-UWB Ranging

Jean-Yves Le Boudec, Jean-Pierre Hubaux, Panagiotis Papadimitratos, Marcin Poturalski, Manuel Flury

To provide high ranging precision in multipath environments, a ranging protocol should find the first arriving path, rather than the strongest path. We demonstrate a new attack vector that disrupts such precise Time-of-Arrival (ToA) estimation, and allows ...
