An integrated geodetic and InSAR technique for the monitoring and detection of active faulting in southwestern Sicily [PDF]
, 2020 We present the results of the analysis of GNSS (Global Navigation Satellite System) and InSAR (Interferometric synthetic-aperture radar) data collected in the frame of a project financed by the “Struttura Terremoti” of INGV (Istituto Nazionale di ...

The Depositional Record, EarlyView.Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

Deep Learning of GNSS Acquisition
Sensors, 2023 Signal acquisition is a crucial step in Global Navigation Satellite System (GNSS) receivers, which is typically solved by maximizing the so-called Cross-Ambiguity Function (CAF) as a hypothesis testing problem. This article proposes to use deep learning models to perform such acquisition, whereby the CAF is fed to a data-driven classifier that outputs ...

Energy Science &Engineering, EarlyView.ABSTRACT Mountain climbing often involves sudden weather changes, group separation, and mobile device battery depletion, which can lead to life‐threatening emergencies. Enhancing survival and extending rescue time in such situations are crucial, making power supply and emergency equipment essential considerations.

Quantitative Analysis to the Impacts of IMU Quality in GPS/INS Deep Integration
Micromachines, 2015 In the Global Positioning System (GPS)/Inertial Navigation System (INS) deep integration system, the pure negative effect of the INS aiding is mainly the INS navigation error that is independent with the motion dynamics, which determine whether the INS ...

Phase Center Corrections for BDS IGSO and MEO Satellites in IGb14 and IGSR3 Frame
Remote Sensing, 2021 As pre-launch antenna calibrations are not available for GPS and GLONASS satellites, the high correlation between the terrestrial scale and phase center offset (PCO) prevents a reliable estimation of the terrestrial scale with GNSS (Global Navigation ...

Land Degradation &Development, EarlyView.ABSTRACT Soil disturbance resulting from forest harvesting activities can have significant and lasting environmental consequences, particularly in sensitive ecosystems such as Mediterranean forests. Skid trails, the routes used by machinery to extract timber, are among the most critical areas of impact, and their detection is critical for assessing ...

Integrating GPS with GLONASS for high‐rate seismogeodesy
Geophysical Research Letters, 2017 High‐rate GPS is a precious seismogeodetic tool to capture coseismic displacements unambiguously and usually improved by sidereal filtering to mitigate multipath effects dominating the periods of tens of seconds to minutes. We further introduced GLONASS (
