Normalized GNSS Interference Pattern Technique

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

It is well known that water level and snow height can be monitored with the ground reflectometry GNSS-R approach [1, 2]. In this approach the antenna situated on a mast, receives a direct GNSS signal coming from the satellite and a nadir signal reflected b ...

Alignment of angular velocity sensors for a vestibular prosthesis

Silvestro Micera

ABSTRACT: Vestibular prosthetics transmit angular velocities to the nervous system via electrical stimulation. Head-fixed gyroscopes measure angular motion, but the gyroscope coordinate system will not be coincident with the sensory organs the prosthetic r ...

U-SBAS: A universal multi-SBAS standard to ensure compatibility, interoperability and interchangeability

Pierre-André Farine, Cyril Botteron, Aleksandar Jovanovic, Youssef Tawk

Several regional augmentation GNSS systems (like SBAS) are already fully operational and other are under development with new frequencies and signals on the way. Therefore, it becomes imperative to guarantee for all GNSS users the compatibility, interopera ...

The IceCube data acquisition system: Signal capture, digitization, and timestamping

Xiaoxia Bai

IceCube is a km-scale neutrino observatory under construction at the South Pole with sensors both in the deep ice (InIce) and on the surface (IceTop). The sensors, called Digital Optical Modules (DOMs). detect, digitize and timestamp the signals from optic ...

New time-dependent slip inversion of Slow Slip Events: application to the 2006 Guerrero SSE

Mathilde Edmée Lucette Radiguet de la Bastaie

The 2006 Slow Slip Event in Guerrero, Mexico, is one of the world's largest SSE observed up to now. Thanks to the development of the Guerrero GPS network, the 2006 event was recorded at 15 continuous GPS stations that allowed a detailed study of the surfac ...
