Ionospheric Sounding and Tomography by GNSS
Studies of the ionosphere and the physics of the ionospheric processes rely on the knowledge of spatial distribution of the ionospheric plasma. Being the propagation medium for radio waves, the ionosphere significantly affects the performance of various navigation, location, and communication systems. Therefore, investigation into the structure of the ionosphere is of interest for many practica...
متن کاملWind Direction Signatures in GNSS-R Observables from Space
Wind speed and direction are important essential climate variables (ECVs). GNSS-R is an emerging remote sensing technique that can be potentially used to retrieve wind speed from space. However, few studies have addressed the wind direction retrieval from spaceborne GNSS-R observables, namely the Delay Doppler map (DDM). In this study, the feasibility of retrieving wind direction from the synth...
متن کاملWavelet Filtering of GNSS Network Data for the Detection and Identification of Ionospheric Disturbances Caused by Tsunamis
Disturbances Caused by Tsunamis Yu-Ming Yang, James L. Garrison, See-Chen Lee Purdue University 1 Problem Statement Acoustic-Gravity Waves (AGWs) in the neutral atmosphere can induce disturbances in the ionosphere that are subsequently observable in trans-ionospheric Global Navigation Satellite System (GNSS) measurements of Total Electron Content (TEC). Disruptive events on the Earth’s surface,...
متن کاملGNSS Array-Based Ionospheric Spatial Gradient Monitoring: Precision and Integrity Analyses
Integrity monitoring and reliable detection of the ionospheric spatial gradient is of importance for various fields including total electron content modeling, radio communication and radar, and differential GNSS applications such as landing, departure and surface operations at an airport. In this contribution, we investigate the precision and the integrity of the ionospheric spatial gradient es...
متن کاملOptimal Spatial Filtering for CV Estimation
Abstract— Muscle fiber conduction velocity (CV) can be estimated by the application of a pair of spatial filters to surface EMG signals and compensation of the spatial filter transfer function with equivalent temporal filters. This method integrates the selection of the spatial filters for signal detection to the estimation of CV. Using this approach, in this study we propose a novel techniqu...
