Regional Model-Based Computerized Ionospheric Tomography Using Gps Measurements: Ionolab-Cit
(Amer Geophysical Union, 2015)
Three-dimensional imaging of the electron density distribution in the ionosphere is a crucial task for investigating the ionospheric effects. Dual-frequency Global Positioning System (GPS) satellite signals can be used to ...
Regularized Estimation of Tec from Gps Data for Certain Midlatitude Stations and Comparison with the Iri Model
(Elsevier Sci Ltd, 2007)
Regularized estimation of Total Electron Content (Reg-Est) is a novel technique which can combine signals from all the satellites for a given instant and given station and estimate the vertical TEC (VTEC) values for any ...
Tomographic Reconstruction Of The Ionospheric Electron Density As A Function Of Space And Time
(Elsevier Sci Ltd, 2009)
Electron density distribution is the major determining parameter of the ionosphere. Computerized Ionospheric Tomography (CIT) is a method to reconstruct ionospheric electron density image by computing Total Electron Content ...
Online User-Friendly Slant Total Electron Content Computation From Iri-Plas: Iri-Plas-Stec
(Amer Geophysical Union, 2014)
Slant total electron content (STEC), the total number of free electrons on a ray path, is an important space weather observable. STEC is the main input for computerized ionospheric tomography (CIT). STEC can be estimated ...
Multipath Separation-Direction Of Arrival (Ms-Doa) With Genetic Search Algorithm For Hf Channels
(Elsevier Sci Ltd, 2009)
Direction-of-Arrival (DOA) defines the estimation of arrival angles of an electromagnetic wave impinging oil a set of sensors. For dispersive and time-varying HF channels, where the propagating wave also suffers from the ...
Investigation of Total Electron Content Variability Due to Seismic and Geomagnetic Disturbances in the Lonosphere
(Amer Geophysical Union, 2010)
Variations in solar, geomagnetic, and seismic activity can cause deviations in the ionospheric plasma that can be detected as disturbances in both natural and man-made signals. Total electron content (TEC) is an efficient ...
