IMPACT OF SENSOR DATA SAMPLING RATE IN GNSS/INS INTEGRATED NAVIGATION WITH VARIOUS SENSOR GRADES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022 The fast-growing small-size equipment requires robust navigation with low power consumption and high positioning accuracy. However, as the mainstream robust navigation method against different environments, GNSS/INS causes excessive power dissipation ...

High-rate GNSS techniques for the detection of large seismic displacements [PDF]
2009 IEEE International Geoscience and Remote Sensing Symposium, 2009 Measurement of co-seismic strong-motion displacements at sub-second temporal resolution is of great importance for earthquake studies. We have investigated the usage of highrate sampled Global Navigation Satellite System (GNSS) data to measure seismic motion by implementing an industrial robot simulating the displacements close to an earthquake ...

High-Rate Altimetry in SNR-Based GNSS-R: Proof-of-Concept of a Synthetic Vertical Array [PDF]
IEEE Geoscience and Remote Sensing Letters, 2021 Global Navigation Satellite System Reflectometry (GNSS-R) has emerged as a promising remote sensing technique for coastal sea level monitoring. The GNSS-R based on signal-to-noise ratio (SNR) observations employs a single antenna and a conventional receiver.

High-rate local sea level monitoring with a GNSS-based tide gauge [PDF]
2010 IEEE International Geoscience and Remote Sensing Symposium, 2010 We present first results from the analysis of high-rate observations with a GNSS-based tide gauge at the Onsala Space Observatory. The goal is to determine local sea level with high temporal resolution. The GNSS-based tide gauge makes use of right-hand circular polarized GNSS signals that are directly received and left-hand circular polarized GNSS ...

GPS Solutions, 2023 AbstractWe combine accelerometer and asynchronous high-rate GNSS data to retrieve dynamic displacements. The method adopts relative GNSS positioning with observations of different sampling rates at rover and reference stations. The objective is to examine the feasibility of downsampling GNSS data at reference stations and thus, verify whether permanent

Supervised Machine Learning of High Rate GNSS Velocities for Earthquake Strong Motion Signals
Journal of Geophysical Research: Solid Earth, 2022 Abstract High rate Global Navigation Satellite System (GNSS) processed time series capture a broad spectrum of earthquake strong motion signals, but experience regular sporadic noise that can be difficult to distinguish from true seismic signals.

First feasibility demonstration of GNSS-seismology for anthropogenic earthquakes detection
Scientific Reports, 2023 High-rate GNSS has been proven effective in characterising waveforms and co-seismic displacements due to medium-to-strong natural earthquakes. No application focused on small magnitude events like shallow anthropogenic earthquakes, where displacements ...
